Sprint today announced that it has upgraded the Sprint Power Vision Network, with the faster EV-DO Revision A technology in the San Diego market - making it the first market in the country to have the technology commercially available. With the upgraded mobile broadband network, customers in San Diego will ultimately be able to utilize richer applications and services such as high-speed video telephony, music on demand, video messaging and large file uploads.

San Diego is the first of 21 markets where Sprint will roll out EV-DO Revision A this year with coverage expected to reach more than 40 million people. Sprint Power Vision users in these markets should experience significantly faster average upload speeds of 300-400 kbps (compared with 50-70 kbps of current EV-DO networks). Average download speeds should also increase to 450 - 800 kbps from 400-700 kbps. By 3Q 2007, Sprint's Power Vision network is expected to be completely upgraded to the faster EV-DO Revision A.

The other markets scheduled to launch this year are:

• Baltimore
• Boston
• Buffalo, N.Y.

Sprint's customers will be able to use the upgraded network to utilize applications such as all IP video telephony, high-performance push-to-talk (walkie-talkie service), multi-user video conferencing, real-time gaming and video streaming of both content and live web cams simultaneously as they become available.
