Most Fools don’t believe in Sprint Nextel (NYSE: S). More than 2,000 have rated the stock in our CAPS database, and their consensus opinion is that it deserves just two out of five possible stars. Ouch.

The few who do believe in Sprint are betting that its fourth-generation (4G) WiMAX network, built in concert with Clearwire (Nasdaq: CLWR), will fuel future revenue and profits.

“The wireless sector is poised to grow exponentially in the near future and live content that requires lots of bandwidth will necessitate a 4G platform,” Foolish investor surena wrote last month.

Uncork the Champagne, Fool.

Sprint and Clearwire this week announced its rollout schedule for WiMAX service in three of the country’s biggest cities: Los Angeles (Nov. 1), New York (Dec. 1), and San Francisco (late December). Comcast will partner with Sprint and Clearwire in lighting the San Francisco network.

Two things make this news interesting for investors. First, the timing. Verizon (NYSE: VZ) plans to light up a competing network based on its version of the long-term evolution technology in 38 cities by year's end.

Second, and more important, is the network itself. Although Verizon is reported to have struck a deal with Apple (Nasdaq: AAPL), these reports also note initial iPhone models built for its CDMA network won’t be able to take advantage of LTE service. AT&T (NYSE: T), meanwhile, doesn’t plan to offer LTE till mid-next year, according to industry news site Fierce Wireless. Throw in the fact that Sprint has tested 4G-ready phones while other carriers will be rushing to fill out a launch lineup, and Sprint could enjoy a few months of a monopoly on 4G phone service in three of the nation’s largest cities.

Sprint. Monopoly. How often have those two words met in the same sentence?

So far, Fools are more excited about infrastructure suppliers  such as Skyworks Solutions (Nasdaq: SWKS) and Qualcomm (Nasdaq: QCOM) than they are Sprint. So be it. Sprint Nextel may not be growing as fast as it once was, but at four times its free cash flow, the company is trading as if its WiMAX rollout is worthless. I doubt that very much.
