Perhaps spurred on by Verizon's rollout schedule -- or the increasingly present threat of Cingular's HSDPA coverage -- Sprint's decided to light a fire under its EV-DO Rev. A rollout plans, promising coverage for a population of 40 million by year end. The upgrade from their existing Rev. 0 network should offer average download speeds of 450-800kbps with a theoretical maximum of 3.1Mbps, up from 300-400Kbps and 1.8Mbps, respectively. Though the upgrade won't likely cause many folks to join the bandwagon, it's a welcome boost for existing subscribers looking to match (or surpass, depending on who you ask) HSDPA performance. Look for the rollout to complete in Q3 2007, with availability of Rev. A handsets and PC peripherals (including an ExpressCard flavor) this fall.
