Motorola's Wireless Broadband CDMA 1X EV-DO Solution to Power ALLTEL's Axcess Broadband Service SCHAUMBURG, Ill., July 26 /PRNewswire-FirstCall/ -- Motorola Inc.'s (NYSE:MOT) CDMA 1xEV-DO wireless broadband solution is scheduled to be deployed by ALLTEL Inc. (NYSE:AT) later this year as it continues rollout of its Axcess Broadband service. "Axcess Broadband gives our customers mobile access to the Internet with speeds that rival wired broadband connections, allowing them to wirelessly and quickly download large, graphic-rich files and streaming video onto their laptops when connected to our network in select markets," said Chris Smith, executive vice president of Network Services, ALLTEL. "ALLTEL's deployment of Axcess Broadband service using Motorola-supplied CDMA infrastructure is an important endorsement of Motorola's wireless broadband technology that allows operators to offer new, high speed services with upgrades to their existing infrastructure," said Fred Wright, senior vice president, Motorola Networks. ALLTEL's Axcess Broadband service lets users access the Internet with bursts up to 2.4 Mbps and average speeds of 300 to 500 Kbps. ALLTEL is deploying the service using plug-in EV-DO carrier channel cards that are installed into existing Motorola CDMA 1X cell sites where broadband data service is to be offered. The network upgrade is coupled with installation of incremental Internet Protocol (IP) radio access call processing equipment in the mobility switching center. CDMA 1xEV-DO is the next step in CDMA data evolution, helping to reduce the cost of delivering data while increasing the typical data throughput speed for subscribers by up to 10X compared to the current CDMA 1X data solution and enabling new interactive software applications to run more efficiently at much faster speeds. Motorola's 1xEV-DO solution is being used by operators in North America, Latin America, and Asia Pacific.
