SOMA Networks Increases Speed and Capacity of Macro Base Station Using New Motorola Single-Board Computer

XIP68 CompactPCI Single-Board Computer Improves Economics of the SOMA™ Solution with Increased Processor and Memory Capabilities

SAN FRANCISCO, Calif., July 8, 2003 – SOMA Networks, Inc., and Motorola Computer Group, a part of Motorola, Inc. (NYSE: MOT), today announced SOMA Networks has chosen the new XIP68 CompactPCI single-board computer for use in the SOMAä macro base station. The XIP68, with its increased processing power and memory, contributes to improved economics for the SOMA solution due to its increased system capacity and advanced application features. Motorola will supply the XIP68 CompactPCI single-board computer as SOMA Networks scales up production for large-scale commercial deployments of its innovative all-IP, fully converged, end-to-end broadband wireless solution, which cost-effectively delivers high-speed Internet access and landline-quality voice services to the residential and small office market.

The SOMA macro base station is the network infrastructure component of the SOMA solution, which also includes the SOMAportä subscriber terminal and the SOMA SoftAirä platform. The SOMA macro base station works in tandem with the advanced SoftAir platform to create a next-generation wireless IP service node that communicates with intelligent subscriber terminals to provide broadband data, landline-quality voice and other advanced applications. A single SOMA macro base station can support thousands of subscribers receiving megabit per second data rates.

To manage the voice, data and multimedia applications, the SOMA macro base station uses the XIP68 CompactPCI single-board computer with an Intel® Pentium® III processor running at 1 GHz. The increased speed and throughput of the Motorola XIP68 CompactPCI single-board computer, combined with up to 1 GB of ECC-enabled SDRAM memory, results in increased system capacity for the SOMA macro base station. The Motorola XIP68 CompactPCI single-board computer also has "universal slot" functionality, which means it can function as a host slot controller, a peripheral slot processor and a bus-free slot operator. The flexibility of the XIP68 CompactPCI allows SOMA to use just one type of board where previously a number of different single-board computers were required. This consolidation simplifies supply chain management, software upgrades, and field service of the base station. All of these advantages add up to significant improvements in the overall economics of the SOMA solution.

"In today's rapidly changing technology arena, communications service providers require a robust broadband network that profitably delivers reliable, high-speed data services and landline-quality voice, and easily accommodates the rapid deployment of new revenue-generating applications and features," said Tom Flak, Vice President of Product Marketing, SOMA Networks. "We found that the standards-based Motorola XIP68 CompactPCI single-board computer meets our stringent requirements by providing the enhanced performance and flexibility that enables our macro base station to function as a powerful, software-driven service node for the quick and profitable delivery of next-generation services."

"The new XIP68 CompactPCI single-board computer is designed to give the optimum balance of performance, functionality and flexibility so our customers can use it as a common platform across their applications," said Harry Weber, Senior Product Manager, Motorola Computer Group. "Additional features such as an Ethernet packet-switched backplane help to future-proof and reduce costs in a next-generation solution such as SOMA's last-mile wireless broadband system. The embedded intelligence and flexibility of the XIP68 CompactPCI single-board computer contributes to improved economics for our customers."
