DTI Demonstrates Advanced Wireless Testing Solutions at ITU Telecom in Geneva

DTI Showcases its claRiFyTM Interference Measurement System, Segue™ Analyzer Wi-Fi Tester, SeeGullTM LX Scanning Receiver, and Model Tuning Solution

Germantown, MD - October 10, 2003 - DTI, a leader in wireless intelligent solutions announced yesterday that it unveiled claRiFy™, a breakthrough propagation and interference measurement solution, and will demonstrate it at the upcoming ITU Telecom trade show in Geneva, Switzerland (October 12th - 18th) in booth 5250. DTI is a PCTEL (PCTI: Nasdaq) company.

In addition, DTI will demonstrate its advanced wireless testing solutions, including: the Segue™ Analyzer, a hand -held Wi -Fi (802.11a/b) test tool; the SeeGull™ LX GSM/WCDMA Scanning Receiver, used for network optimization; and its DBS (Distance -Based Sampling) system, a Model Tuning solution.

claRiFy™'s breakthrough technology improves network performance and increases capacity by providing GSM Wireless Operators with a complete evaluation of their network's RF environment. Network -wide RF measurements obtained with claRiFy™ enable carriers to rigorously evaluate co -channel and adjacent channel interference issues. This results in more effective fine -tuned propagation models, which improve Automatic Frequency Planning (AFP) and Automatic Cell Planning (ACP) applications, and allow carriers to optimize network performance without investing in additional infrastructure. This intelligence translates directly into the bottom line savings, as capital spending for network infrastructure is reduced. "Co -channel interference is a complex problem that has vexed wireless carriers for many years," said Paul Kline, President and Co -Founder of DTI. Using DTI's proprietary technology, claRiFy™ provides carriers with a powerful tool to improve coverage, service quality and customer satisfaction."

DTI's Segue Analyzer™ is a handheld test and security verification tool for Wi -Fi (802.11a/b) networks. This state -of -the -art device was designed with the network administrator/MIS person in mind to analyze and optimize 2.4 GHz and 5.6 GHz WLAN and WWANs. Segue Analyzer™ monitors traffic, identifies regions and sources of interference, detects unwanted subscribers and access points, reports throughput, and measures network and radio parameters.

The SeeGull™ LX scanning receiver is used by wireless carriers to obtain network performance data through drive tests, site surveys, base station monitoring, and network coverage analysis. The SeeGull™ LX receiver features dual mode/dual band operation, layer 3 decoding, a built -in spectrum analyzer, and rapid demodulation of signals. These features provide increased analysis capabilities for RF performance, and enhance the carrier's visibility into their network, dramatically simplifying troubleshooting and network optimization.

DTI's DBS (Distance -Based Sampling) solution is used for propagation model tuning during the various stages of the network lifecycle. The rapid and accurate measurements of this easy -to -use system enhance network deployment and network optimization. This cost -effective product also supports Lee Criteria, a sampling methodology that improves the reliability of estimating signal strength in RF predication tools.
