Sprint's summer of WiMax - Telecom News Analysis

As expected, Sprint Nextel Corp. (NYSE: S) launched its 4G Now service -- running over the Clearwire LLC (Nasdaq: CLWR) mobile WiMax network -- today in Atlanta, Las Vegas, and Portland, Ore.

The operator is expected to track Clearwire's launches closely with its own 3G-to-4G roaming service throughout the remainder of 2009. Clearwire said last week that it will cover 25 markets and over 30 million users by the end of this year. (See Clearwire Promises Growth Spurt...)
