Sprint unveils dual 3G/4G modem

Sprint has launched a dual 3G/WiMax (4G) modem in a necessary step that buys it some time as its next generation network is rolled out beyond Baltimore.

The telecom company said the Sprint 3G/4G USB Modem U300 will be available in stores--in the Baltimore area for now--Dec. 21. Given that WiMax is far from national today Sprint had to offer a dual mode modem to ensure wireless broadband coverage across the U.S.

Sprint launched WiMax service in Baltimore and plans to roll it out into other markets in 2009. The problem: Once you leave those markets you're out of WiMax and wireless service. Sprint's modem will solve that problem. Sprint is betting on WiMax to stop the subscriber churn.

Here's a look at the technical specs:

• 4G speeds (average download speeds of 2-4 Mbps) in Baltimore today, and soon in other major cities.
• 3G speeds (average download speeds of 600Kbps – 1.4 Mbps) across Sprint's nationwide network.
• Backwards compatible to the Sprint EV-DO/Rev 0 and 1XRTT networks.
• The modem will connect to the fastest network available.
• The modem will run you $149.99 with a two-year subscription and a $50 mail-in rebate.

For now, this modem is a Baltimore story. In January, Best Buy will also carry the modem. If you're in Baltimore you'll find the dual mode modem at Sprint's stores in Annapolis, Baltimore, Bel Air, Columbia, Glen Burnie, Owings Mills, Hanover and Towson.
