PCTEL CLARIFY CDMA Solution Evaluates Network Performance

New Orleans -- CTIA Wireless 2005 -- PCTEL announced today the introduction of a CDMA CLARIFY Interference Measurement Solution. CLARIFY provides a complete evaluation of an RF network's performance, providing visibility into difficult interference issues. PCTEL demonstrated its CLARIFY CDMA solution at the CTIA Wireless 2005 Show this week.

CLARIFY detects and measures interference in cellular networks. It enhances network optimization and simplifies technically difficult network problems without requiring network modifications, off-hours driving, continuous wave (CW) transmitters, or other expensive diagnostic methods. CLARIFY data are essential to cell planning and optimization.

"We are pleased to be able to respond to the many customer requests for CLARIFY CDMA by announcing the addition of CDMA to our CLARIFY product line," Larry Swift, general manager, PCTEL RF Solutions Group, said. "This new solution will be invaluable to operators as they grow their CDMA networks and manage deployment of overlay EVDO data networks."

In today's wireless networks, several radio frequency (RF) characteristics impact service quality and network efficiency. Understanding interference and the precise identification of base stations that are sources of RF propagation and pilot pollution in CDMA networks are crucial factors in cell planning and network optimization. Current methods use unreliable predictive models or expensive and time consuming drive testing data (either pilot or CW measurements). Network-wide measurements obtained with CLARIFY CDMA enhance the ability of network engineers to solve difficult interference problems, fine-tune propagation models, and to improve Automatic Cell Planning (ACP) results. The CLARIFY CDMA approach provides more sensitive measurements (CLARIFY CDMA has 30dB of dynamic range) and is less costly to operate than current methodologies.
