MELBOURNE, FL/BOSTON, MA May 25, 2011 — Harris Corporation (NYSE:HRS), an international communications and information technology company, has been selected to design and implement a Harris P25IP (Project 25 to the power of Internet Protocol) trunked simulcast radio system in Linn County, Iowa, which includes Cedar Rapids, the largest city in the state. The system will provide reliable, mission-critical voice and data communications for first responders who serve the county’s more than 200,000 residents over 724 square miles. The contract also includes Harris Unity XG-100P Full-Spectrum Multiband portable radios for improved communication on the VHF, UHF, 700 and 800 MHz frequency bands.

“Seeing the success experienced by neighboring Johnson County with its Harris P25 trunked radio system, it was an easy decision to implement a similar upgrade,” said Sheriff Brian Gardner, Linn County, Iowa. “Our new standards-based system will give our agencies exactly what we need — a highly-available, scalable radio solution for reliable voice and data communications that will support our first responders during both large-scale emergency situations and day-to-day operations.”

The Harris P25IP digital simulcast system will consist of six sites across Linn County. The system meets current P25 standard and is software upgradeable to P25 Phase 2 standards for future scalability. Harris partner and locally-based RACOM will provide technical services and support. Linn County’s system also includes 600 Unity XG-100P Full-Spectrum Multiband portable radios that will provide public safety officials with reliable and interoperable voice and data communications among agencies in the county as well as with first responders in surrounding counties. The Unity XG-100P radios provide Linn County with multimode interoperability to communicate across the VHF, UHF, 700 and 800 MHz spectrum.

“The unique geography of Linn County requires a highly available radio system with end-to-end IP connectivity to deliver reliable communications capabilities to first responders,” said Steve Marschilok, president, Harris Public Safety and Professional Communications. “By choosing our Harris P25IP system, Linn County will be able to meet these requirements, and more, for consistently secure, interoperable voice and data transmissions in both rural and urban locations.”

The Harris P25IP system includes the Harris VIDA^® network, which is a unified IP-based voice and data communication platform. VIDA delivers full IP management features, including interoperability without intervention of console operators, IP consoles, and other benefits inherent in open IP architecture systems.
