Business Editors

GERMANTOWN, Md.--(BUSINESS WIRE)--May 6, 2003

Dynamic Telecommunications, Inc. (DTI), a PCTEL (Nasdaq:PCTI) company, announced the release of its Forward Dedicated Control Channel (FDCCH) Decoding Receiver for IS-136 wireless networks. This precise, DSP-based scanning receiver provides service-critical measurements of IS-136 wireless networks, enabling wireless service providers to optimize wireless network performance via drive testing.

The new IS-136 FDCCH Decoding Receiver will offer both commercial and government customers a new level of visibility into IS-136 networks, enabling them to perform protocol analysis functions and monitoring on both control channels and traffic channels. In contrast to other IS-136 monitoring products, the IS-136 FDCCH Decoding Receiver from DTI does not use a cellular handset to monitor control channels. This solution avoids the limitation of monitoring only one channel per handset. DTI's handset-free solution also eliminates the requirement for network registration, a long-standing burden for government-related applications (e.g., security, criminal investigations, etc.).

"The FDCCH Decoding Receiver for IS-136 demonstrates DTI's commitment to supporting all the important wireless protocols with industry-leading test and measurement tools," said Paul Kline, DTI's president. "These products improve network performance by effectively providing radio propagation measurement, protocol demodulation and statistical data for cellular, PCS, and other wireless networks. They also provide the flexibility required in non-commercial applications", added Kline.

The FDCCH Decoding Receiver for IS-136 decodes system identity (SID) and Dedicated Control Channel (DCCH) structure messages from the FDCCH, demodulating IS-136 layer 3 messages and Digital Verification Color Code (DVCC) messages on control and traffic channels, all in one receiver. DVCC decoding is used in identifying the transmitting base station, providing critical network performance information to wireless carriers.

The FDCCH Decoding Receiver for IS-136, which is available now, is sold through OEMs to cellular and PCS service providers worldwide. The list price for a single unit is less than $8,500.
