Conquering many of the smaller markets already throughout the US, Sprint is expediting the roll out of its 4G WiMAX network into several markets by the end of 2010. At that point, Sprint's network will cover more than 120 million people with their next generation high speed data network – giving itself a leg up on some of its competitors who have yet to start. These markets include the cities of Boston, Denver, Kansas City, Houston, Minneapolis, New York, San Francisco and Washington, D.C. Many people might have questioned Sprint's move of not rolling the ball first thing in these markets, but to their credit, it's a wiser move to slowly branch out to the smaller markets first so they can slowly gather some techniques in perfecting their network. It would really have been a disaster if they did expand to these larger markets first and experienced some kind of catastrophic event that may cause some doubt in their capacity to compete in the market. With a rumored 4G handset in the works for Sprint, the outlook may seem a bit more appealing with the notion of potentially being the first to offer one.
