Sticking to its word, Sprint has lit up its first EV-DO Revision A mobile broadband network today, covering San Diego to start with 20 additional markets set to launch before year's end. The upgraded Sprint Power Vision network boosts real-life upload speeds to the 300-400 kbps level, kicking the current 50-70 kbps transfer rates back to 1995 where they belong. Observed download speeds also get a shot in the arm, albeit a more modest jump to 450–800 kbps, up from 400-700 kbps. While San Diegans get all the bragging rights for the time being, folks in New York, Los Angeles, Washington, D.C., and seventeen other markets can rest easy knowing that they'll be able to bask in some Rev. A goodness by the end of the year -- check the link below for the complete list. And if you're not on that list, Sprint says it should have its network completely upgraded by the third quarter of 2007.
