   We are a leading developer and supplier of cost-effective, software-based
connectivity solutions for data transmission in a wide range of communications
environments. Our solutions enable high speed internet access and other
communications applications through emerging digital subscriber line, wireless
and other broadband networks as well as existing analog networks. Broadband
networks enhance voice and data capabilities beyond that which is offered by
the existing analog networks. Connectivity solutions refer to any method for
connecting one circuit, network or computer to another. We have developed a
proprietary software architecture that is easily upgradeable, minimizing the
risk of technological obsolescence and enables widespread internet access and
other communications applications through PCs and alternative internet access
devices.
 
   We are one of the pioneers in developing host signal processing technology,
a proprietary set of algorithms that enables cost-effective, software-based
digital signal processing solutions. Host signal processing technology and the
software architecture on which it is based utilize the computational and
processing resources of a host central processor rather than requiring
additional special-purpose hardware. Based on our own research and testing, the
reduction of hardware components in our host signal processing architecture can
reduce space requirements by up to 50% and power requirements by up to 70%
compared to conventional hardware-based solutions.
 
   We believe our 1999 soft modem shipments represented 85% of the worldwide
soft modem market based on projections from Cahners In-Stat Group. Various
original equipment manufacturers, including Acer, Compaq, Dell, emachines,
Fujitsu and Sharp, have integrated our soft modems into their products.
 
   In recent years, dramatic increases in business and consumer demand for
multimedia information, entertainment and voice and data communication have
resulted in a corresponding increase in demand for high speed remote access.
The accelerated growth of content-rich applications, which demand high
bandwidth, has changed the nature of information networks. High-speed
connectivity is now a commonplace requirement for business, government,
academic and home environments. These market trends have resulted in a
significant increase in the demand for connectivity devices. International Data
Corporation estimates that by 2003, the number of internet connectivity devices
in use will grow to over 722 million.
 
   Our host signal processing architecture, which involves running software on
a host computer rather than using dedicated processing hardware, allows us to
quickly and cost-effectively capitalize on this rapid growth in demand for
connectivity devices. We believe that we can use our intellectual property
portfolio to readily adapt to the speed and design requirements of emerging
connectivity technologies. For example, we have developed LiteSpeed, a host
signal processing architecture solution, in response to growing market
acceptance of G.Lite, a digital subscriber line technology that enables
downstream data transmission speeds of up to 1.5 Mbps and upstream data
transmission speeds of up to 512 Kbps over existing copper telephone lines.
Downstream transmission refers to the transmission of data from the central
office to the customer premise, and upstream transmission of data refers to the
reverse. By providing connectivity solutions that can be easily adapted to new
standards and protocols, we simplify purchasing decisions and accelerate
deployment times for original equipment manufacturers.
 
   We are also developing a G.DMT standard version of asymmetric digital
subscriber line customer premise equipment which will allow for full-rate data
transmission. Full-rate solutions can accommodate eight megabits per second
downstream and one megabit per second upstream.
 
   In February 2000, we acquired Voyager Technologies, a pioneer of short-range
wireless technology. We believe Voyager Technologies provides us with the core
wireless technology and the resources to allow us to accelerate our penetration
into emerging growth markets for wireless data networking, high speed internet
access through cellular handsets, shared broadband internet access through home
networks (commonly referred to as residential gateway solutions) and cordless
handsets.
 
   Our principal executive offices are located at 1331 California Circle,
Milpitas, California 95035. Our telephone number is (408) 965-2100.

                                  RISK FACTORS
 
   Before you invest in our common stock, you should carefully consider the
various risks, including those described below, together with all of the other
information included in this prospectus. Risks and uncertainties not presently
known to us or that we currently consider to be immaterial may also impair our
business operations. If any of these risks actually occur, our business,
financial condition or operating results could be adversely affected. In that
case, the trading price of our common stock could decline and you could lose
all or part of your investment.
 
                         Risks Related to Our Business
 
Our sales are concentrated among a limited number of customers and the loss of
one or more of these customers could cause our revenues to decrease.
 
   Our sales are concentrated among a limited number of customers. If we were
to lose one or more of these customers, or if one or more of these customers
were to delay or reduce purchases of our products, our revenues may decrease.
For the year ended December 31, 1999, approximately 79% of our revenues were
generated by five of our customers. Talent Trade Asia and Askey accounted for
47% and 13% of our revenues for the year ended December 31, 1999, respectively.
These customers may in the future decide not to purchase our products at all,
purchase fewer products than they did in the past or alter their purchasing
patterns, because:
 
  . we do not have any long-term purchase arrangements or contracts with
    these or any of our other customers,
 
  . our product sales to date have been made primarily on a purchase order
    basis, which permit our customers to cancel, change or delay product
    purchase commitments with little or no notice and without penalty, and
 
  . many of our customers also have pre-existing relationships with current
    or potential competitors which may affect our customers' purchasing
    decisions.
 
   We expect that a small number of customers will continue to account for a
substantial portion of our revenues for at least the next 12 to 18 months and
that a significant portion of our sales will continue to be made on the basis
of purchase orders.
 
We have significant sales and operations concentrated in Asia. Political and
economic instability in Asia and difficulty in collecting accounts receivable
may make it difficult for us to maintain or increase market demand for our
products.
 
   Our sales to customers located in Asia accounted for 99%, 76% and 77% of our
total revenues for the years ended December 31, 1999, 1998 and 1997,
respectively. The predominance of our sales are in Asia, mostly in Taiwan and
China, because our customers are primarily motherboard or modem board
manufacturers that are located there. In many cases, our indirect original
equipment manufacturer customers specify that our products be included on the
modem boards or motherboards, the main printed circuit board containing the
central processing unit of a computer system, that they purchase from board
manufacturers, and we sell our products directly to the board manufacturers for
resale to our indirect original equipment manufacturer customers, both in the
United States and internationally. Due to the industry wide concentration of
modem manufacturers in Asia, we believe that a high percentage of our future
sales will continue to be concentrated with Asian customers. As a result, our
future operating results could be uniquely affected by a variety of factors
outside of our control, including:
 
  . political and economic instability in Asia,
 
  . changes in tariffs, quotas, import restrictions and other trade barriers
    which may make our products more expensive than our competitors'
    products,
 
                                       6

<PAGE>
 
  . delays in collecting accounts receivable, which we have experienced from
    time to time, and
 
  . fluctuations in the value of Asian currencies relative to the U.S.
    dollar, which may make it more costly for us to do business in Asia which
    may in turn make it difficult for us to maintain or increase our
    revenues.
 
   To successfully expand our sales internationally, we must strengthen foreign
operations, hire additional personnel and recruit additional international
distributors and resellers. This will require significant management attention
and financial resources. To the extent that we are unable to effect these
additions in a timely manner, we may not be able to maintain or increase market
demand for our products in Asia and internationally, and our operating results
could be hurt.
 
Continuing decreases in the average selling prices of our products could result
in decreased revenues.
 
   Product sales in the connectivity industry have been characterized by
continuing erosion of average selling prices. Price erosion experienced by any
company can cause revenues and gross margins to decline. The average selling
price of our products has decreased by approximately 46% from October 1995 to
December 1999. We expect this trend to continue.
 
   In addition, we believe that the widespread adoption of industry standards
in the soft modem industry is likely to further erode average selling prices,
particularly for analog modems. Adoption of industry standards is driven by the
market requirement to have interoperable modems. End users need this
interoperability to ensure modems from different manufacturers communicate with
each other without problems. Historically, users have deferred purchasing
modems until these industry standards are adopted. However, once these
standards are accepted, it lowers the barriers to entry and price erosion
results. Decreasing average selling prices in our products could result in
decreased revenues even if the number of units that we sell increases.
Therefore, we must continue to develop and introduce next generation products
with enhanced functionalities that can be sold at higher gross margins. Our
failure to do this could cause our revenues and gross margins to decline.
 
Our gross margins may vary based on the mix of sales of our products and
services, and these variations may hurt our net income.
 
   We derive a significant portion of our sales from our software-based
connectivity products. We expect margins on newly introduced products generally
to be higher than for our existing products. However, due in part to the
competitive pricing pressures that affect our products and in part to
increasing component and manufacturing costs, we expect margins from both
existing and future products to decrease over time. In addition, licensing
revenues from our products historically have provided higher margins than our
product sales. Changes in the mix of products sold and the percentage of our
sales in any quarter attributable to products as compared to licensing revenues
will cause our quarterly results to vary and could result in a decrease in net
income.
 
Our future success depends on our ability to develop and successfully introduce
new and enhanced products that meet the needs of our customers.
 
   Our future success depends on our ability to anticipate our customers' needs
and develop products that address those needs. Introduction of new products and
product enhancements will require that we coordinate our efforts with those of
our suppliers to rapidly achieve volume production. If we fail to coordinate
these efforts, develop product enhancements or introduce new products that meet
the needs of our customers as scheduled, our revenues may be reduced and our
business may be harmed. We cannot assure you that product introductions will
meet the anticipated release schedules.

Our revenues may fluctuate each quarter due to both domestic and international
seasonal trends.
 
   We have experienced and expect to continue to experience seasonality in
sales of our connectivity products. These seasonal trends materially affect our
quarter-to-quarter operating results. Our revenues are typically higher in the
third and fourth quarters due to the back-to-school and holiday seasons as well
as purchasers of PCs making purchase decisions based on their calendar year-end
budgeting requirements. As a result, we generally expect revenue levels for the
first quarter to be less than those for the preceding quarter.
 
   We are currently expanding our sales in international markets, particularly
in Asia, Europe and South America. To the extent that our revenues in Asia,
Europe or other parts of the world increase in future periods, we expect our
period-to-period revenues to reflect seasonal buying patterns in these markets.
 
Any delays in our normally lengthy sales cycles could result in customers
canceling purchases of our products.
 
   Sales cycles for our products with major customers are lengthy, often
lasting six months or longer. In addition, it can take an additional six months
or more before a customer commences volume production of equipment that
incorporates our products. Sales cycles with our major customers are lengthy
for a number of reasons:
 
  . our original equipment manufacturer customers usually complete a lengthy
    technical evaluation of our products, over which we have no control,
    before placing a purchase order,
 
  . the commercial integration of our products by an original equipment
    manufacturer is typically limited during the initial release to evaluate
    product performance, and
 
  . the development and commercial introduction of products incorporating new
    technologies frequently are delayed.
 
   A significant portion of our operating expenses is relatively fixed and is
based in large part on our forecasts of volume and timing of orders. The
lengthy sales cycles make forecasting the volume and timing of product orders
difficult. In addition, the delays inherent in lengthy sales cycles raise
additional risks of customer decisions to cancel or change product phases. If
customer cancellations or product changes occur, this could result in the loss
of anticipated sales without sufficient time for us to reduce our operating
expenses.
 
We expect that our operating expenses will increase substantially in the future
and these increased expenses may diminish our ability to remain profitable.
 
   Although we have been profitable in recent years, we may not remain
profitable on a quarterly or annual basis in the future. We anticipate that our
expenses will increase substantially over at least the next three years as we:
 
  . further develop and introduce new applications and functionality for our
    host signal processing technology,
 
  . conduct research and development and explore emerging product
    opportunities in digital technologies and wireless and cable
    communications,
 
  . expand our distribution channels, both domestically and in our
    international markets, and
 
  . pursue strategic relationships and acquisitions.
 
   In order to maintain profitability we will be required to increase our
revenues to meet these additional expenses. Any failure to significantly
increase our revenues as we implement our product, service, distribution and
strategic relationship strategies would result in a decrease in our overall
profitability.
 
   To date, we have principally relied upon our distributor sales organization
for product sales to smaller accounts. Our direct sales efforts have focused
principally on board manufacturers and smaller PC original
 
                                       8

equipment manufacturers. To increase penetration of our target customer base,
including large, tier-one original equipment manufacturers, we must
significantly increase the size of our direct sales force and organize and
deploy sales teams targeted at specific domestic tier-one original equipment
manufacturer accounts. If we are unable to expand our sales to additional
original equipment manufacturers, our revenues may not meet analysts'
expectations which could cause our stock price to drop.
 
We must accurately forecast customer demand for our products. If there is an
unexpected fluctuation in demand for our products, we may incur excessive
operating costs or lose product revenues.
 
   We must forecast and place purchase orders for specialized semiconductor
chips, such as the application specific integrated circuit, coder/decoder and
discrete access array, or data access arrangement, components of our modem
products, several months before we receive purchase orders from our own
customers. This forecasting and order lead time requirement limits our ability
to react to unexpected fluctuations in demand for our products. These
fluctuations can be unexpected and may cause us to have excess inventory, or a
shortage, of a particular product. In the event that our forecasts are
inaccurate, we may need to write down excess inventory. For example, we were
required to write down inventory in the second quarter of 1996 in connection
with a product transition within our 14.4 Kbps product family. Similarly, if we
fail to purchase sufficient supplies on a timely basis, we may incur additional
rush charges or we may lose product revenues if we are not able to meet a
purchase order. These failures could also adversely affect our customer
relations. Significant write-downs of excess inventory or declines in inventory
value in the future could cause our net income and gross margin to decrease.
 
We rely heavily on our intellectual property rights which offer only limited
protection against potential infringers. Unauthorized use of our technology may
result in development of products that compete with our products which could
cause our market share and our revenues to be reduced.
 
   Our success is heavily dependent upon our proprietary technology. We rely
primarily on a combination of patent, copyright and trademark laws, trade
secrets, confidentiality procedures and contractual provisions to protect our
proprietary rights. These means of protecting our proprietary rights may not be
adequate. We hold a total of 40 patents, a number of which cover technology
that is considered essential for International Telecommunications Union
standard communications solutions, and also have 29 additional patent
applications pending or filed. These patents may never be issued. These
patents, both issued and pending, may not provide sufficiently broad protection
against third party infringement lawsuits or they may not prove enforceable in
actions against alleged infringers.
 
   Despite precautions that we take, it may be possible for unauthorized third
parties to copy aspects of our current or future products or to obtain and use
information that we regard as proprietary. We may provide our licensees with
access to our proprietary information underlying our licensed applications.
Additionally, our competitors may independently develop similar or superior
technology. Finally, policing unauthorized use of software is difficult, and
some foreign laws, including those of various countries in Asia, do not protect
our proprietary rights to the same extent as United States laws. Litigation may
be necessary in the future to enforce our intellectual property rights, to
protect our trade secrets or to determine the validity and scope of the
proprietary rights of others. Litigation could result in substantial costs and
diversion of resources.
 
   We have received, and may receive in the future, communications from third
parties asserting that our products infringe on their intellectual property
rights, that our patents are unenforceable or that we have inappropriately
licensed our intellectual property to third parties. These claims could affect
our relationships with existing customers and may prevent potential future
customers from purchasing our products or licensing our technology. Because we
depend upon a limited number of products, any claims of this kind, whether they
are with or without merit, could be time consuming, result in costly
litigation, cause product shipment delays or require us to enter into royalty
or licensing agreements. In the event that we do not prevail in litigation, we
could be prevented from selling our products or be required to enter into
royalty or licensing agreements on terms which may not be acceptable to us. We
could also be prevented from selling our products or be required
 
                                       9

<PAGE>
 
to pay substantial monetary damages. Should we cross license our intellectual
property in order to obtain licenses, we may no longer be able to offer a
unique product. Other than the ESS Technology lawsuit described elsewhere in
this prospectus, no material lawsuits relating to intellectual property are
currently filed against us.
 
   New patent applications may be currently pending or filed in the future by
third parties covering technology that we use currently or may use in the
future. Pending U.S. patent applications are confidential until patents are
issued, and thus it is impossible to ascertain all possible patent infringement
claims against us. We believe that several of our competitors, including
Lucent, Motorola and Texas Instruments, may have a strategy of protecting their
market share by filing intellectual property claims against their competitors
and may assert claims against us in the future. The legal and other expenses
and diversion of resources associated with any such litigation could result in
a decrease in our revenues.
 
   In addition, some of our customer agreements include an indemnity clause
that obligates us to defend and pay all damages and costs finally awarded by a
court should third parties assert patent and/or copyright claims against our
customers. As a result, we may be held responsible for infringement claims
asserted against our customers. If our financial reserves for potential future
license fees are less than any actual fees that we are required to pay, our net
income would be reduced.
 
If our financial reserves for potential future license fees are less than any
actual fees that we are required to pay, our net income would be reduced.
 
   We have established and recorded on a monthly basis a reserve for payment of
future license fees based upon our estimate as to the likely amount of the
licensing fees that we may be required to pay in the event that licenses are
obtained. We believe that it is typical for participants in the modem industry
to obtain licenses in exchange for grants of cross licenses rather than for
payment of fees and we have based our estimates on our understanding of the
license fee practices of other segments of our industry. Our reserves may not
be adequate because of factors outside of our control and because these license
fee practices in the modem industry may not be applicable to our experience.
 
Competition in the connectivity market is intense, and if we are unable to
compete effectively, the demand for, or the prices of, our products may be
reduced.
 
   The connectivity device market is intensely competitive. We may not be able
to compete successfully against current or potential competitors. Our current
competitors include 3Com, Conexant, ESS Technology, Lucent Technologies,
Motorola and SmartLink. We expect competition to increase in the future as
current competitors enhance their product offerings, new suppliers enter the
connectivity device market, new communication technologies are introduced and
additional networks are deployed.
 
   We may in the future also face competition from other suppliers of products
based on host signal processing technology or on new or emerging communication
technologies, which may render our existing or future products obsolete or
otherwise unmarketable. We believe that these competitors may include Alcatel,
Analog Devices, Aware, Broadcom, Efficient Networks, ITeX, Terayon
Communications, Texas Instruments and Virata.
 
   As a result of our February 2000 acquisition of Voyager Technologies, we
anticipate that we will enter the markets for wireless Internet connectivity
and wireless home networking. These markets are intensely competitive. We
believe that our future competitors in these markets may include Aironet,
Breezecom, Conexant, Lucent, Intersil, Motorola, Proxim and Symbol
Technologies.
 
   We believe that the principal competitive factors required by users and
customers in the connectivity product market include compatibility with
industry standards, price, functionality, ease of use and customer service and
support. Although we believe that our products currently compete favorably with
respect to these factors, we may not be able to maintain our competitive
position against current and potential competitors.

In order for us to maintain our profitability and continue to introduce and
develop new products for emerging markets, we must attract and retain our
executive officers and qualified technical, sales, support and other
administrative personnel.
 
   Our past performance has been and our future performance is substantially
dependent on the performance of our current executive officers and certain key
engineering, sales, marketing, financial, technical and customer support
personnel. If we lose the services of one or more of our executives or key
employees, a replacement could be difficult to recruit and we may not be able
to grow our business.
 
   We maintain "key person" life insurance policies on Peter Chen, our Chairman
and Chief Executive Officer, William Wen-Liang Hsu, our Vice President,
Engineering, and Han Yeh, our Vice President, Technology, in the face amount of
$1 million for each individual. However, these insurance policies may not
adequately compensate us for the loss of services of any of these individuals.
 
   We intend to hire a significant number of additional engineering, sales,
support, marketing and finance personnel in the future. Competition for
personnel, especially engineers and marketing and sales personnel in Silicon
Valley, is intense. We are particularly dependent on our ability to identify,
attract, motivate and retain qualified engineers with the requisite education,
background and industry experience. As of December 31, 1999, we employed a
total of 65 people in our engineering department, over half of whom have
advanced degrees. In the past we have experienced difficulty in recruiting
qualified engineering personnel, especially developers, on a timely basis. If
we are not able to hire at the levels that we plan, our ability to continue to
develop products and technologies responsive to our markets will be impaired.
 
Our acquisition of Voyager Technologies and any future acquisitions may be
difficult to integrate, disrupt our business, dilute stockholder value or
divert management attention.
 
   We acquired Voyager Technologies on February 24, 2000. We are in the initial
stages of integrating Voyager Technologies into PCTEL. We may encounter
problems associated with the integration of Voyager Technologies including:
 
  . difficulties in assimilation of acquired personnel, operations,
    technologies or products,
 
  . unanticipated costs associated with the acquisition,
 
  . diversion of management's attention from other business concerns,
 
  . adverse effects on our existing business relationships with our and
    Voyager Technologies' customers, and
 
  . inability to retain employees of Voyager Technologies.
 
   As part of our business strategy, we may in the future seek to acquire or
invest in additional businesses, products or technologies that we believe could
complement or expand our business, augment our market coverage, enhance our
technical capabilities or that may otherwise offer growth opportunities. These
future acquisitions could pose the same risks to our business posed by the
acquisition described above. In addition, we could use substantial portions of
our available cash to pay for future acquisitions. We could also issue
additional securities as consideration for these acquisitions, which could
cause our stockholders to suffer significant dilution.
 
We have experienced significant growth in our business in recent periods and
failure to manage our growth could strain our management, financial and
administrative resources.
 
   Our ability to successfully sell our products and implement our business
plan in rapidly evolving markets requires an effective management planning
process. Future expansion efforts could be expensive and put a strain on our
management by significantly increasing the scope of their responsibilities and
our resources by
 
                                       11

<PAGE>
 
increasing the number of people using them. We have increased, and plan to
continue to increase, the scope of our operations at a rapid rate. Our
headcount has grown and will continue to grow substantially. Our headcount
increased from 95 at December 31, 1998 to 144 at December 31, 1999. In
addition, we expect to continue to hire a significant number of new employees.
To effectively manage our growth, we must maintain and enhance our financial
and accounting systems and controls, integrate new personnel and manage
expanded operations.
 
We rely on independent companies to manufacture, assemble and test our
products. If these companies do not meet their commitments to us, our ability
to sell products to our customers would be impaired.
 
   We do not have our own manufacturing, assembling or testing operations.
Instead, we rely on independent companies to manufacture, assemble and test the
semiconductor chips which are integral components of our products. Most of
these companies are located outside of the United States. There are many risks
associated with our relationships with these independent companies, including
reduced control over:
 
 
  . delivery schedules,
 
  . quality assurance,
 
  . manufacturing costs,
 
  . capacity during periods of excess demand, and
 
  . access to process technologies.
 
   In addition, the location of these independent parties outside of the United
States creates additional risks resulting from the foreign regulatory,
political and economic environments in which each of these companies exists.
Further, some of these companies are located near earthquake fault lines. While
we have not experienced any material problems to date, failures or delays by
our manufacturers to provide the semiconductor chips that we require for our
products, or any material change in the financial arrangements we have with
these companies, could have an adverse impact on our ability to meet our
customer product requirements.
 
   We design, market and sell application specific integrated circuits and
outsource the manufacturing and assembly of the integrated circuits to third
party fabricators. The majority of our products and related components are
manufactured by five principal companies: Taiwan Semiconductor Manufacturing
Corporation, ST Microelectronics, Kawasaki/LSI, Silicon Labs and Delta
Integration. We expect to continue to rely upon these third parties for these
services. Currently, the data access arrangement chips used in our soft modem
products are provided by a sole source, Silicon Labs, on a purchase order
basis, and we have only a limited guaranteed supply arrangement under a
contract with our supplier. We are currently in the process of qualifying a
second source for our data access arrangement chips. Although we believe that
we would be able to qualify an alternative manufacturing source for data access
arrangement chips within a relatively short period of time, this transition, if
necessary, could result in loss of purchase orders or customer relationships,
which could result in decreased revenues.
 
Undetected software errors or failures found in new products may result in loss
of customers or delay in market acceptance of our products.
 
   Our products may contain undetected software errors or failures when first
introduced or as new versions are released. To date, we have not been made
aware of any significant software errors or failures in our products. However,
despite testing by us and by current and potential customers, errors may be
found in new products after commencement of commercial shipments, resulting in
loss of customers or delay in market acceptance.

                         Risks Related to Our Industry
 
If the market for applications using our host signal processing technology does
not grow as we anticipate, or if our products are not accepted in this market,
our revenues may stagnate or decrease.
 
   Our success depends on the growth of the market for applications using our
host signal processing technology. Market demand for host signal processing
technology depends primarily upon the cost and performance benefits relative to
other competing solutions. This market has only recently begun to develop and
may not develop at the growth rates that have been suggested by industry
estimates. Although we have shipped a significant number of soft modems since
we began commercial sales of these products in October 1995, the current level
of demand for soft modems may not be sustained or may not grow. If customers do
not accept soft modems or the market for soft modems does not grow, our
revenues will decrease.
 
   Further, we are in the process of developing next generation products and
applications which improve and extend upon our host signal processing
technology, such as a G.Lite modem solution and a remote access solution. If
these products are not accepted in our markets when they are introduced, our
revenues and profitability will be negatively affected.
 
Our industry is characterized by rapidly changing technologies. If we do not
adapt to these technologies, our products will become obsolete.
 
   The connectivity product market is characterized by rapidly changing
technologies, limited product life cycles and frequent new product
introductions. To remain competitive in this market, we have been required to
introduce many products over a limited period of time. For example, we
introduced a 14.4 Kbps product in 1995, a 28.8 Kbps product in 1996, a 33.6
Kbps product in late 1996, a non-International Telecommunications Union
standard 56 Kbps modem in the second half of 1997 and a v.90 International
Telecommunications Union standard 56 Kbps modem in early 1998. The market for
high speed data transmission is also characterized by several competing
technologies that offer alternative broadband solutions which allow for higher
modem speeds and faster internet access. These competing broadband technologies
include digital subscriber line, wireless and cable. However, substantially all
of our current product revenue is derived from sales of analog modems, which
use a more conventional technology. We must continue to develop and introduce
technologically advanced products that support one or more of these competing
broadband technologies. If we are not successful in our response, our products
will become obsolete and we will not be able to compete effectively.
 
Changes in laws or regulations, in particular, future FCC regulations affecting
the broadband market, internet service providers, or the communications
industry could negatively affect our ability to develop new technologies or
sell new products and therefore, reduce our profitability.
 
   The jurisdiction of the Federal Communications Commission, or FCC, extends
to the entire communications industry, including our customers and their
products and services that incorporate our products. Future FCC regulations
affecting the broadband access services industry, our customers or our products
may harm our business. For example, future FCC regulatory policies that affect
the availability of data and internet services may impede our customers'
penetration into their markets or affect the prices that they are able to
charge. In addition, international regulatory bodies are beginning to adopt
standards for the communications industry. Although our business has not been
hurt by any regulations to date, in the future, delays caused by our compliance
with regulatory requirements may result in order cancellations or postponements
of product purchases by our customers, which would reduce our profitability.

                       Risks Related to our common stock
 
Substantial future sales of our common stock in the public market may depress
our stock price.
 
   Our current stockholders hold a substantial number of shares, which they
will be able to sell in the public market in the near future. Sales of a
substantial number of shares of our common stock could cause our stock price to
fall.
 
Provisions in our charter documents may inhibit a change of control or a change
of management which may cause the market price for our common stock to fall and
may inhibit a takeover or change in our control that a stockholder may consider
favorable.
 
   Provisions in our charter documents could discourage potential acquisition
proposals and could delay or prevent a change in control transaction that our
stockholders may favor. These provisions could have the effect of discouraging
others from making tender offers for our shares, and as a result, these
provisions may prevent the market price of our common stock from reflecting the
effects of actual or rumored takeover attempts and may prevent stockholders
from reselling their shares at or above the price at which they purchased their
shares. These provisions may also prevent changes in our management that our
stockholders may favor. Our charter documents do not permit stockholders to act
by written consent, do not permit stockholders to call a stockholders meeting
and provide for a classified board of directors, which means stockholders can
only elect, or remove, a limited number of our directors in any given year.
 
   Our board of directors has the authority to issue up to 5,000,000 shares of
preferred stock in one or more series. The board of directors can fix the
price, rights, preferences, privileges and restrictions of this preferred stock
without any further vote or action by our stockholders. The rights of the
holders of our common stock will be affected by, and may be adversely affected
by, the rights of the holders of any preferred stock that may be issued in the
future. Further, the issuance of shares of preferred stock may delay or prevent
a change in control transaction without further action by our stockholders. As
a result, the market price of our common stock may drop. The board of directors
has not elected to issue additional shares of preferred stock since the initial
public offering on October 19, 1999.
 
Our stock price may be volatile based on a number of factors, some of which are
not in our control.
 
   The trading price of our common stock has been highly volatile. Our stock
price could be subject to wide fluctuations in response to a variety of
factors, many of which are out of our control, including:
 
  . actual or anticipated variations in quarterly operating results,
 
  . announcements of technological innovations,
 
  . new products or services offered by us or our competitors,
 
  . changes in financial estimates by securities analysts,
 
  . conditions or trends in our industry,
 
  . our announcement of significant acquisitions, strategic partnerships,
    joint ventures or capital commitments,
 
  . additions or departures of key personnel, and
 
  . sales of common stock by us or our stockholders.
 
   In addition, the Nasdaq National Market, where many publicly held
telecommunications companies, including our company, are traded, often
experiences extreme price and volume fluctuations. These fluctuations often
have been unrelated or disproportionate to the operating performance of these
companies. The trading prices of many technology companies continue to trade at
multiples of earnings or revenues which are substantially above historic
levels. These trading prices and multiples may not be sustainable. These broad
 
                                       14

<PAGE>
 
market and industry factors may seriously harm the market price of our common
stock, regardless of our actual operating performance. In the past, following
periods of volatility in the market price of an individual company's
securities, securities class action litigation often has been instituted
against that company. This type of litigation, if instituted, could result in
substantial costs and a diversion of management's attention and resources.
 
There May Be Sales Of A Substantial Amount Of Our Common Stock After The
Expiration of Certain Lock Up Periods, Including Our Executive Officers And
Directors, And These Sales Could Cause Our Stock Price To Fall
 
   Our current stockholders hold a substantial number of shares, which they
will be able to sell in the public market in the near future.
 
   As of October 19, 1999, our executive officers, directors and substantially
all of our stockholders, who held an aggregate of 10,128,057 shares of our
common stock, or approximately 93.54% of our total outstanding shares before
the initial public offering, had executed lock-up agreements that prevent them
from selling or otherwise disposing of our common stock for a period of 180
days from the date of our initial public offering, or October 17, 2000, without
the prior written approval of Banc of America Securities LLC. These lock-up
agreements will expire on April 14, 2000, and on April 17, 2000, the first day
of trading following the expiration of the lock-up period, an aggregate of
2,944,020 shares will be eligible for sale, in some cases subject only to the
volume, manner of sale and notice requirements of Rule 144 under the Securities
Act. In addition, the majority of our executive directors, officers,
significant shareholders and shareholders participating pursuant to the
offering have executed lock-up agreements that prevent them from selling or
otherwise disposing of our common stock for a period of 90 days from the date
of our follow on public offering, or April 17, 2000, without the prior written
approval of Banc of America Securities LLC. These lock up agreements will
expire on July 10, 2000, and on July 11, 2000, the first day of trading
following the expiration of the lock-up period, an aggregate of 5,054,691
shares will be eligible for sale, in some cases subject only to the volume,
manner and sale and notice requirements of Rule 144 under the Securities Act.
 
   Sales of a substantial number of shares of our common stock could cause our
stock price to fall. In addition, the sale of these shares could impair our
ability to raise capital through the sale of additional stock.

                              SELLING STOCKHOLDERS
 
   All of the shares of common stock owned by the selling stockholders were
issued under our 1995 Stock Option Plan, 1997 Stock Option Plan and 1998
Employee Stock Purchase Plan. Beneficial ownership calculations are determined
in accordance with the rules of the SEC and are based on 16,560,335 shares
outstanding as of December 31, 1999; in computing the number of shares
beneficially owned by a person and the percentage ownership of that person,
shares of common stock that are presently exercisable or that will become
exercisable with in 60 days of March 31, 2000 are deemed outstanding for such
person, but are not treated as outstanding for the purpose of computing the
percentage ownership of any other person. Until we satisfy the requirements for
use of Form S-3, which we anticipate will occur in October 2000, the volume
limitations specified in Rule 144(e) under the Securities Act concerning the
amount of securities to be offered by each person and any other person with
whom he or she is acting in concert for the purpose of selling PCTEL
securities, during any three-month period apply to the sale of the securities
registered hereunder. The following table shows the names of the selling
stockholders and the number of shares of common stock to be sold by them

                              PLAN OF DISTRIBUTION
 
   The selling stockholders may sell all or a portion of the shares from time
to time on the Nasdaq National Market for their own accounts at prices
prevailing in the public market at the times of such sales. The selling
stockholders may also make private sales directly or through one or more
brokers. These brokers may act as agents or as principals. The selling
stockholders will pay all sales commissions and similar expenses related to the
sale of the shares. We will pay all expenses related to the registration of the
shares.
 
   The selling stockholders and any broker executing selling orders on behalf
of the selling stockholders may be considered an underwriter under the
Securities Act. As a result, commissions received by a broker may be treated as
underwriting commissions under the Securities Act. Any broker-dealer
participating as an agent in that kind of transaction may receive commissions
from the selling stockholders and from any purchaser of shares.
 
   Underwriters, dealers and agents may be entitled to indemnification by us
against certain civil liabilities, including liabilities under the Securities
Act. Underwriters, dealers and agents also may be entitled to contribution with
respect to payments made by the underwriters, dealers or agents, under
agreements between us and the underwriters, dealers and agents.
 
   Any securities covered by this Prospectus that qualify for sale pursuant to
Rule 144 under the Securities Act may be sold under that Rule rather than
pursuant to this Prospectus. There can be no assurance that the Selling
Stockholders will sell any or all of the Shares of common stock offered
hereunder.

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
   Our certificate of incorporation limits the liability of directors to the
maximum extent permitted by Delaware law. Delaware law provides that directors
of a corporation will not be personally liable for monetary damages for breach
of their fiduciary duties as directors, except liability for:
 
  . any breach of their duty of loyalty to the corporation or its
    stockholders,
 
  . acts of omissions not in good faith or which involve intentional
    misconduct or a knowing violation of law,
 
  . unlawful payments of dividends or unlawful stock repurchases or
    redemptions, or
 
  . any transaction from which the director derived an improper personal
    benefit.
 
   The limitations of liability do not apply to liabilities arising under the
federal securities laws and do not affect the availability of equitable
remedies such as injunctive relief or rescission.
 
   Our certificate of incorporation and bylaws provide that we will indemnify
our directors and officers and may indemnify our employees and other agents to
the fullest extent permitted by law. We believe that indemnification under our
bylaws covers at least negligence and gross negligence on the part of
indemnified parties. Our bylaws also permit us to secure insurance on behalf of
any officer, director, employee or other agent for any liability arising out of
his or her actions in their capacity as an officer, director, employee or other
agent, regardless of whether the bylaws would permit indemnification.
 
   We have entered into agreements to indemnify our directors and executive
officers, in addition to the indemnification provided for in our bylaws. These
agreements primarily provide for indemnification of our directors and executive
officers for judgment, fines, settlement amounts and expenses, including
attorneys' fees incurred by the director, executive officer or controller in
any action or proceeding, including any action by or in the right of PCTEL,
arising out of the person's services as a director, executive officer or
controller of us, any of our subsidiaries or any other company or enterprise to
which the person provides services at our request. We believe that these
provisions and agreements are necessary to attract and retain qualified persons
as directors and executive officers.
 
   The limited liability and indemnification provisions in our certificate of
incorporation and bylaws may discourage stockholders from bringing a lawsuit
against our directors for breach of their fiduciary duty and may reduce the
likelihood of derivative litigation against our directors and officers, even
though a derivative action, if successful, might otherwise benefit us and our
stockholders. A stockholder's investment in us may be adversely affected to the
extent we pay the costs of settlement or damage awards against our directors
and officers under these indemnification provisions.
 
   At present, there is no pending litigation or proceeding involving any of
our directors, officers or employees in which indemnification is sought, nor
are we aware of any threatened litigation that may result in claims for
indemnification.
 
   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of us under the
foregoing provisions or otherwise, we have been advised that in the opinion of
the Securities and Exchange Commission this indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable.

<PAGE>
 
   We have entered into agreements to indemnify our directors and executive
officers, in addition to the indemnification provided for in our bylaws. These
agreements primarily provide for indemnification of our directors and executive
officers for judgment, fines, settlement amounts and expenses, including
attorneys' fees incurred by the director, executive officer or controller in
any action or proceeding, including any action by or in the right of PCTEL,
arising out of the person's services as a director, executive officer or
controller of us, any of our subsidiaries or any other company or enterprise to
which the person provides services at our request. We believe that these
provisions and agreements are necessary to attract and retain qualified persons
as directors and executive officers.
 
   The limited liability and indemnification provisions in our certificate of
incorporation and bylaws may discourage stockholders from bringing a lawsuit
against our directors for breach of their fiduciary duty and may reduce the
likelihood of derivative litigation against our directors and officers, even
though a derivative action, if successful, might otherwise benefit us and our
stockholders. A stockholder's investment in us may be adversely affected to the
extent we pay the costs of settlement or damage awards against our directors
and officers under these indemnification provisions.
 
   At present, there is no pending litigation or proceeding involving any of
our directors, officers or employees in which indemnification is sought, nor
are we aware of any threatened litigation that may result in claims for
indemnification.
 
   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of us under the
foregoing provisions or otherwise, we have been advised that in the opinion of
the Securities and Exchange Commission this indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable.
 
Item 7. Exemption From Registration Claimed
 
   The issuance of the Shares being offered by the Form S-3 resale prospectus
were deemed exempt from registration under the Securities Act in reliance upon
Section 4(2) of the Securities Act or Regulation D promulgated thereunder, or
Rule 701 promulgated under Section 3(b) of the Securities Act, as transactions
by an issuer not involving a public offering or transactions pursuant to
compensatory benefit plans and contracts relating to compensation as provided
under such Rule 701. The recipients of securities in each such transaction
represented their intention to acquire the securities for investment only and
not with a view to sell or for sale in connection with any distribution thereof
and appropriate legends were affixed to the share certificates and instruments
issued in such transactions. All recipients had adequate access, through their
relationship to PCTEL, to information about the Registrant.

Item 9. Undertakings
 
   (a)  The undersigned registrant hereby undertakes:
 
     (1) To file, during any period in which offers or sales are being made,
  a post-effective amendment to this registration statement to include any
  material information with respect to the plan of distribution not
  previously disclosed in the registration statement or any material change
  to such information in the registration statement.
 
     (2) That, for the purpose of determining any liability under the
  Securities Act, each such post-effective amendment shall be deemed to be a
  new registration statement relating to the securities offered therein, and
  the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof.
 
     (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
 
   (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange
Act (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in the registration statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
   (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted for directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

Re:  Registration Statement on Form S-8/S-3

Dear Ladies and Gentlemen:

          We have examined the Registration Statement on Form S-8/S-3 (the
"Registration Statement") to be filed by you with the Securities and Exchange
Commission on or about April 14, 2000, in connection with the registration under
the Securities Act of 1933, as amended, of an aggregate of 7,470,291 shares of
your common stock (the "Future Issuance Shares"), reserved for future issuance
pursuant to your 1995 Stock Option Plan, 1997 Stock Option Plan, as amended,
1998 Employee Stock Purchase Plan and 1998 Director Option Plan (collectively,
the "Plans") and an aggregate of 326,094 shares registered on behalf of certain
selling stockholders listed in the Registration Statement (the "Selling
Stockholder Shares").  As your legal counsel, we have reviewed the actions
proposed to be taken by you in connection with the issuance and sale of the
Future Issuance Shares and the sale of the Selling Stockholder Shares.

          It is our opinion that the Future Issuance Shares, when issued and
sold in the manner referred to in the Plans and pursuant to the agreements which
accompany the Plans, will be legally
 and validly issued, fully paid and
nonassessable. It is also our opinion that the Selling Stockholder Shares are
legally and validly issued, fully paid and nonassessable.

          We consent to the use of this opinion as an exhibit to the
Registration Statement and further consent to the use of our name wherever
appearing in the Registration Statement, including any Prospectus constituting a
part thereof, and any amendments thereto.

                                   Very truly yours,

                                   /s/ WILSON SONSINI GOODRICH & ROSATI

Purchase Plan and 1998 Director Option Plan, of our report dated January 24,
