3Com Supplies Critical Wireless Technology for New Sprint Wireless Web Service.

SANTA CLARA, Calif.--(BUSINESS WIRE)--Aug. 24, 1999--

Sprint's wireless division today announced that 3Com Corporation (NASDAQ:COMS) is supplying an integral part of the underlying wireless data access technology for its new Sprint PCS Wireless Web service, announced earlier this month. 3Com's CDMA InterWorking Function (IWF) is the only circuit-switched wireless data access gateway solution for Code Division Multiple Access (CDMA) networks such as the all-digital, nationwide Sprint PCS network.

"3Com's CDMA IWF technology is part of the magic behind our new Sprint PCS Wireless Web offerings," said Keith Paglusch, senior vice president of operations, Sprint PCS. "3Com provides the network infrastructure platform that enables Sprint PCS' easy-to-use, breakthrough service. It helped enable Sprint PCS to take its place ahead of all its competitors in the wireless industry."

Unlike some wireless carriers that have announced wireless data products, the introduction of the Sprint PCS Wireless Web service is not a limited geographic trial or test launch. It will be launched full-scale and nationwide in late September to the nearly 4 million subscribers of Sprint PCS, the fastest-growing U.S. wireless carrier.

3Com's CDMA IWF platform serves as a gateway between wireless CDMA and wireline networks. Use of 3Com's patent-pending IWF QuickNet Connect feature eliminates the need for a network modem, providing mobile users with direct digital access to the Internet and corporate intranets. By bypassing the PSTN, mobile subscribers minimize toll charges and network setup time, establishing connections in as little as 5 to 7 seconds.

"Up to now, user adoption of wireless data technology has been inhibited by a number of key barriers, including high cost, spotty geographic coverage, slow transmission speed, and inadequate security. The Sprint PCS service is impressive because it addresses these key issues. Service prices are reasonable, nationwide coverage will be available immediately, transmission speeds of 14.4 kbps can be achieved, and the Sprint PCS digital network offers an inherent level of security," said Becky Diercks, director, wireless research, Cahners In-Stat Group. "3Com's CDMA IWF platform allows fast setup times and eliminates the need for wireless modems, which allows users to save hundreds of dollars. It is an important cornerstone of Sprint's Wireless Web solution."

The CDMA IWF equipment connects directly to wireless switches to provide the interworking and protocol conversions required to deliver circuit-switched data capabilities to mobile data users.

"3Com is the only company offering a complete CDMA IWF wireless data access solution in the industry today," said Ben Cardwell, director of wireless product management, 3Com Carrier Systems. "Our equipment provides transparent, high-speed, reliable CDMA data connections for a full spectrum of devices including Palm(R) Computing connected organizers, laptops, PDAs, and new smartphones, enabling Sprint PCS to offer mobile users data connectivity to the Internet and private corporate networks."

3Com's IWF technology is based on the company's award-winning Total Control(R) multiservice access platform, which provides telecommunications carriers and service providers a powerful and highly reliable networking solution, including support for remote access, carrier-grade IP telephony, IP fax, virtual private networking (VPN) and other converged voice, video and data applications.

3Com introduced the IWF technology last October as a new capability for its CDMA solution. 3Com is the world's leading maker of CDMA wireless data infrastructure equipment, with virtually 100 percent of the domestic U.S. market and an estimated 95 percent of the global market.
