WEST MELBOURNE, Fla., June 28, 2011 /PRNewswire/ -- RELM Wireless Corporation (NYSE Amex: RWC) announced today that it has provided ARINC's Interoperability Test and Demonstration Center (ITDC) with P25 digital portable trunked land mobile radios. The KNG P800 model has successfully completed Project 25 Trunked interoperability testing in accordance with the Project 25 Compliance Assessment Program (P25CAP). This testing was conducted by a National Institutes of Standards and Technology (NIST) recognized test laboratory and validates interoperability under the Project 25 (P25) standard established by the Telecommunications Industry Association (TIA) and the Association of Public-Safety Communications Officials (APCO). "RELM Wireless is excited to participate in this one-of-a-kind testing resource for our industry," stated RELM President and CEO David Storey. "Our KNG Series trunking radios address new customers who were previously outside the scope of our product line. We welcome this opportunity to document the performance, reliability, and interoperability of RELM radio products alongside the products of our industry peers." Today's land mobile radios continue to differ widely in their operational characteristics. Despite P25 Compliance Assessment Programs conducted by many LMR manufacturers, there are still questions about real-world operation and interoperability. The ARINC Interoperability Test and Demonstration Center (ITDC) enables independent, hands-on testing of LMR performance across multiple platforms, and objective performance evaluations. It is a unique, vendor-neutral platform where makers of Land Mobile Radio (LMR) equipment, their customers and technology partners can test performance characteristics and evaluate the interoperability of radio systems. "Purchasers of Land Mobile Radio systems today want more information about usability," said Marvin Ingram, ARINC Public Safety Systems Senior Director. "They ask whether a radio is easy to program, manage, and deploy. The ARINC lab works in areas that Compliance Assessment Programs may leave out—including product usability and actual interoperability across specific platforms in the real world." About APCO Project 25 (P25) APCO Project 25 (P25), which requires interoperability among compliant equipment regardless of the manufacturer, was established by the Association of Public-Safety Communications Officials and is approved by the U.S. Department of Homeland Security. The shift toward interoperability gained momentum as a result of significant communications failures during emergency events. RELM was one of the earliest manufacturers of P25-compliant products, and today remains a staunch supporter of the P25 standard.
