Earlier that week, Sprint Nextel made good on its promise to introduce a device featuring dual-mode 3G/4G capability on Clearwire’s fledgling WiMAX (4G) network, which is up and running in Baltimore and slated to go on line in Portland, Ore., early next year.

“We promised the market that we would have a dual-mode device by the end of that year, and that’s what we delivered,” said Sprint spokesperson John Polivka.

But the new dual-mode U300 modem is

merely the first device to come out of the wireless carrier’s long-range plans for a device portfolio that will consist of single-mode 4G devices, embedded 4G laptops, and dual-mode 3G/4G devices. The advantage of the latter products, which will all be capable of delivering WiMAX downlink speeds of two to four Mbps, is that they can “fall back on 3G whenever they are beyond a WiMAX service area,” Polivka said.
