Today Sprint Nextel and Clearwire announced the official launch and availability of their WiMax wireless broadband network in a handful of markets. The largest two markets launched are Chicago, Illinois, and Dallas-Ft. Worth, Texas. A number of markets are now live in North Carolina as well, including Cary, Chapel Hill, Charlotte, Durham, Greensboro, High Point, Raleigh, and Winston-Salem. Residents of these markets will be able to purchase laptop dongles that can access the WiMax network and Sprint's EVDO 3G network in areas where WiMax isn't available.
From the posted numbers, I would assume so. Those depend on latency over raw bandwidth correct? won't be as quick as fiber optic, but it should be at least as good as DSL (heck 3g aircards are decent for latency)
