Press Release: Sun/Sprint & PCS Vision Services

SUN MICROSYSTEMS WORKS WITH SPRINT TO POWER ENHANCED THIRD GENERATION NETWORK AND PCS VISION(SM) SERVICES


SANTA CLARA, Calif. and OVERLAND PARK, Kansas -- August 26,
2002 -- Sun Microsystems, Inc. today announced that Sun products and technologies provide valuable infrastructure and service delivery technology for Sprint's PCS Vision(sm) - the company's revolutionary Third Generation (3G) wireless
products and services - and the upgraded 3G 1X wireless network - that recently debuted nationwide.

Sprint, a pioneer in communications network technologies, and Sun Microsystems, an innovator of Internet systems and software, are delivering the first nationwide convergence of Internet services, wireless data and voice to consumers and business people. Both companies share the common
vision that next generation services must be based on open standards that support rapid innovation and faster time to market. This initiative builds on the existing alliance between Sprint and Sun to deliver integrated customer solutions.

Working end-to-end from the backend server system to the mobile handset, Sun's technologies, including Sun(tm)ONE software, Java (tm) technology and Sun servers, give Sprint a scalable, secure standards-based platform for the delivery of interactive wireless data services to Sprint's more than 15
million wireless customers.

"Sun Microsystems has played a pivotal role in our migration to next generation Network services," said William T. Esrey, Chairman and Chief Executive Officer of Sprint. "As the convergence of the Internet and wireless technology gains momentum in the market, we will continue to rely on Sun's technologies -- both hardware and software -- to provide the
scalability and reliability we need to successfully change the way Sprint wireless customers work, learn, play and communicate."

Initially, PCS Vision from Sprint will include services that allow consumer and business customers to use their Vision-enabled PCS Devices to take and receive pictures, check personal and corporate e-mail, play games with full-color graphics and polyphonic sounds and browse the Internet wirelessly with speeds comparable to a home computer's dial-up connection. Sprint plans to continue enriching the customer experience throughout the remainder of this year and into 2003 with an evolving set of applications, content and new capabilities such as streaming audio and video, and even faster data speeds.

"The shift to providing clarity you can see and hear has revolutionized virtually every aspect of wireless service from Sprint," said Esrey. "And Sun technology touches many areas."

Because Sprint required a high degree of service availability and uptime, the company chose Sun Netra (tm) and Sun Fire (tm) servers running Sun ONE software to build the foundation of their 3G network. Sprint's commitment to open standards has been further emphasized by the choice of the Java 2 Platform, Micro Edition(tm) (J2ME(tm)) as the content platform for the delivery of a vast array of applications and content to Sprint customers. Sun Professional Services and Java Engineering were also tapped by Sprint to provide consulting services for Sprint Vision Wireless Services.

"Sprint's 3G launch is a significant event both for the wireless industry and Sun," said Scott McNealy, Chairman, President and CEO, Sun Microsystems. "Sprint's approach is an example of end-to-end design in action. By choosing Sun's open-standards based architecture, Sprint is now able to rapidly expand their 3G Network in order to add services that will meet customer needs as they arise."
