Sprint seems ready to take its WiMAX network to the next level. If you want fast mobile broadband you should either move to Baltimore where the service is active or wait for 2009 and to 2010 for WiMAX to arrive in your city. This year Atlanta, Charlotte, Chicago, Dallas, Ft. Worth, Honolulu, Las Vegas, Philadelphia, Portland and Seattle will get the 4G upgrade while next year Boston, Houston, New York, San Francisco and Washington D.C. will receive the WiMAX. And according to Sprint “several new 4G devices planned for 2009 and 2010, including a single-mode 4G data card, embedded laptops, a small-office-home-office broadband modem and a tri-mode phone.”
