Nextel Brazil Selects Harris Microwave's TRuepoint(TM) Microwave Digital Radio To Expand Network RESEARCH TRIANGLE PARK, N.C., April 5 /PRNewswire-FirstCall/ -- Harris Corporation (NYSE:HRS), a leading global provider of wireless equipment and services, today announced that Nextel Brazil, a division of NII Holdings, Inc. (NASDAQ:NIHD) (formerly known as Nextel International) has selected its next-generation TRuepoint(TM) digital point-to-point radios to deliver voice and data services for Nextel Brazil's cellular network expansion, in addition to improving coverage within existing networks. "Our decision to select Harris' TRuepoint radios was based on both performance and Harris' track record of customer service," said Dushyant Gandhi, vice president and chief technical officer of Nextel Brazil. "TRuepoint's higher capacity and greater frequency range offers us the flexibility we need to extend our reach to even the most remote locations. In addition, Harris' responsive support allows us to quickly augment our network and reap the benefits of the TRuepoint platform." As a global partner of Nextel Communications Inc. (NASDAQ:NXTL), Harris has worked extensively with the carrier to install, engineer, manage and support its global network in markets around the world. In 1999, the Harris Microwave Communications Division signed a strategic relationship agreement with NII to support the delivery of digital wireless communications across its managed properties in Latin America. Harris Microwave has since served as the primary supplier of microwave radio to NII in Mexico, Brazil and Argentina. For this project, Nextel Brazil and Harris are working together to deploy TRuepoint 5000 radios across the entire Nextel Brazil network. While Nextel Brazil will be operating the TRuepoint on a PDH platform, the radio's SDH interface provides the option of migrating to a higher capacity capable of handling greater communication streams. The TRuepoint radios will be used alongside Nextel Brazil's existing Harris network, which is comprised of the Microstar(R) and Megastar(R) digital point-to-point radios and the NetBoss(R) network management platform. Combined, these products ensure a fully functional and cost-effective backhaul network capable of delivering voice and data communications to Nextel's subscribers in the region. "We're proud to have maintained such a strong relationship with Nextel Brazil," said Juan Diaz, Latin America managing director of Harris Microwave Communications Division. "Nextel Brazil's dedication to provide reliable cellular communications to their subscribers matches our dedication to provide superior products and services to the wireless industry."
