ComOpt Joins DTI's Teaming Program

Dynamic Telecommunications (DTI), a PCTEL (Nasdaq:PCTI) company, announced today that ComOpt has become the latest member of the DTI claRiFy(TM) Teaming Program. The Teaming Program promotes the use of empirical interference data to enhance the effectiveness of industry-leading planning and optimization tools. Participants also coordinate marketing efforts and accelerate product integration.

The DTI Teaming Program focuses on advanced network planning tools and techniques that are critically important to wireless carriers. These tools and techniques include Automatic Frequency Planning (AFP), Automatic Cell Planning (ACP), Propagation Modeling, Quality of Service (QoS) Prediction, and other areas of wireless network optimization. ComOpt, an established and recognized leader in the wireless industry, specializes in wireless network design and optimization and their products include solutions for automatic frequency planning, automatic cell planning and measured data handling. By integrating their products, ComOpt and DTI provide wireless operators and consultants enhanced network optimization through the combination of successful optimization tools with empirical and accurate drive test data. Carriers can now benefit directly from this product integration. Without additional investment in network infrastructure, they can expand network coverage and increase capacity, data throughput, and transmission quality by utilizing the output of the optimization tools that are populated with the empirical data provided by the claRiFy system. DTI and ComOpt will also undertake joint promotional and marketing efforts to support claRiFy(TM), CellOpt(R) AFP, CellOpt(R) ACP and CellOpt(R) MDA products.

"ComOpt is happy to partner with DTI as their new measurement data collection system claRiFy enhances the accuracy of our automatic wireless optimization applications though high-quality input data, even in cases where co-channel interference exists", says Joachim Samuelsson, President of ComOpt.

"Our Teaming arrangement with ComOpt demonstrates our commitment to providing best-in-class solutions to wireless systems engineers," said Paul Kline, DTI's President. "ComOpt is a respected leader in frequency and cell planning tools with an outstanding reputation for their tools. ClaRiFy data improves the heuristic accuracy of their tools and will benefit wireless carriers," added Kline.

About claRiFy

ClaRiFy is a novel measurement system that improves spectrum utilization and network quality, reduces capital cost, and increases network operator's efficiency by accurately measuring the propagation and interference of GSM, CDMA and WCDMA networks. ClaRiFy simplifies some of the most technically difficult network problems by identifying the contributing sources of power on a single channel (called "co-channel interference"). In addition, claRiFy provides complete ("key-up" level) data without any need to manipulate the wireless network. The propagation and interference data from claRiFy can be used as input to planning tools (AFP, ACP, or network modeling) and/or the troubleshooting process. ClaRiFy takes the guess work out of the network performance analysis and helps carriers meet targeted capacity levels while maximizing utilization of existing infrastructure.
