GERMANTOWN, Md., Sep 18, 2003 (BUSINESS WIRE) --

DTI, a leader in wireless intelligence, today announced its new GSM scanning receiver. With co-channel interference (C/I) measurements, faster scanning speeds and spectrum analysis, the SeeGull^™ LX GSM scanning receiver provides crucial capabilities for carriers and service providers to test and optimize their wireless network. Additionally, this receiver improves channel-scanning rates and enables multi-tasking. DTI is a PCTEL (PCTI: Nasdaq) company.

Scanning receivers make network parameters visible to wireless carriers. Wireless carriers currently use DTI's scanners to acquire network performance data through drive tests, site surveys, base station monitoring, and network coverage analysis. The SeeGull^™ LX GSM scanning receiver enhances the carrier's visibility into their network, simplifying troubleshooting and network optimization. Critical features include reliable C/I measurements and the accurate identification of BSICs (Base Station Identification Codes). The SeeGull^™ LX GSM scanning receiver also establishes a new standard for the identification of critical system messages (including Cell ID, Mobile Country Code, Mobile Network Code, and Location Area Code). In comparison to mobile test phones, which provide these messages on the Best Server (one channel) only, DTI's GSM receiver can decode them on all channels. Wireless operators use these system messages to identify the origin of RF signals transmitted in their networks.

"We are very excited about providing the SeeGull^™ LX GSM scanning receiver to the wireless testing community. This high-speed receiver provides reliable C/I measurements and accurate spectrum analysis. The release of this product marks another example of our commitment to providing value added test solutions," said Paul Kline, DTI's president. "Service providers and carriers can now test and troubleshoot their GSM networks much more efficiently than was possible before. Our customers will realize better optimization of network performance, enhanced quality of service, and improved wireless coverage", added Kline.

DTI's latest GSM receiver has a scanning speed of 500 channel/second. The high-speed platform also provides the ability for the user to perform multiple functions simultaneously compared to other tools that only support one function at a time. In addition, this new receiver provides higher measurement accuracy and sensitivity, better immunity to interference, and increased sensitivity to BSIC decoding. The new built-in spectrum analyzer feature provides an effective means to detect and troubleshoot frequency-related problems. The available option of Distance Based Sampling (DBS) provides a complete solution for model tuning during network deployment and network optimization. The receiver has an optional built-in GPS, and is available as a single band (850, 900, 1800, or 1900 MHz) or a dual-band (850/1900 or 900/1800 MHz) receiver.

The SeeGull^™ LX GSM scanning receiver is available now and is sold to OEMs and cellular and PCS service providers worldwide.
