Yeah, the summer has been a little boring in the financial world. Inflation fears, a few blockbuster earnings reports, and downright weird behavior from a CEO haven't been enough to pique investors' interest. But what about a major collaboration between broadband giants to overthrow the status quo and bring lightning-fast mobile broadband to the masses?

Sounds good to me. And it sounded really good to investors in Clearwire (NASDAQ:CLWR), the new teammate of Sprint Nextel (NYSE:S) in a pact to accelerate deployment of WiMAX networks. Shares in Clearwire closed 34% higher on Thursday, giving the cash-bleeding, earnings-challenged firm a market capitalization greater than $5 billion.

The deal calls for the two companies to collaborate on developing and building a nationwide mobile broadband network based on WiMAX technology. Each company will be responsible for portions of the network, swapping some spectrum licenses in the process. The companies will also jointly market the new services, set to launch in the first half of 2008. I wonder what they'll call it -- SprintClearMax?

The partnership should accelerate the deployment of WiMAX networks and dramatically cut the costs each company would have shouldered individually. This is good news, particularly for Sprint Nextel, which has been under pressure from shareholders to fix internal operational issues before going on a big spending binge with next-generation WiMAX plans.

The news is bound to spur high-fives from fans on the sidelines as well -- Intel (NASDAQ:INTC) and Motorola (NASDAQ:MOT) are both big proponents of mobile WiMAX networks. But what's that? Do I hear a few boos coming from somewhere in the crowd?

Oh, that must be Qualcomm (NASDAQ:QCOM), or maybe an AT&T (NYSE:T) or Verizon (NYSE:VZ) fan in an oversized foam hat -- they're not big fans of Wi-Fi or WiMAX. Incumbents tend to be ardent home-team boosters, you know.

The announcement is only a letter of intent, and referees may blow the whistle on the play. The Department of Justice and the Federal Communications Commission will be reviewing the replay tape and could interfere with the deal. But I suspect the two new teammates will successfully break any tackles to make nationwide WiMAX mobile broadband a reality next year.
