Many hedge fund and telecom execs have bought up various bands of spectrum in hopes of converting it for wireless networks. The FCC has denied several requests, keeping its strident allotment for airwaves, but the commission recently gave the rare green light to Dish Network.

“Late Tuesday, the FCC unanimously approved [Dish Chairman Charlie] Ergen’s plan,” the Wall Street Journal reports. “Under the order, Dish would be required to not use a portion of its spectrum to avoid interference with neighboring airwaves, according to FCC officials. The company would also be required to cover at least 70 percent of the new network in each of its geographic license areas within seven years.”

Ergen started assembling the spectrum five years ago through government auctions and investments in flailing satellite companies, spending roughly $3 billion. “At a stroke, the FCC has now raised its value to as much as $12 billion, according to some analysts’ estimates. Mr. Ergen has to do the hard work of putting that spectrum to use or getting FCC approval to sell it,” the article states.

“Wireless service could give Dish an important new line of business in a mature U.S. pay TV market, where its cable TV rivals are able to sell popular ‘bundles’ of telephone, television, and high-speed Internet service.” Rather than building its own network, Dish could partner with a carrier like Sprint Nextel, or potentially even an outside company like Google, to offer wireless service with the spectrum.

“Consumers, meanwhile, could benefit whatever Dish decides, as the FCC’s decision frees up more bandwidth for data-hungry devices like smartphones and tablets,” explains WSJ. “The drawn-out process of converting that spectrum also highlighted how slowly regulators have moved to put much-needed airwaves to more valuable uses.”

A new spectrum sharing rule proposed by the Federal Communications Commission would be the biggest wireless regulatory change in decades and could prove a pivotal move in addressing ever-increasing data traffic. “Under the proposed rule, wireless carriers, corporate offices, or researchers could reserve pieces of that spectrum in different regions and at different times — a system managed by a central database,” Technology Review explains.

“The approach guarantees that the spectrum will be available and not subject to interference in certain areas by a crush of new users, as might happen if the new chunk of spectrum were made available with no regulation at all.”

The step “is a critical milestone,” says David Tennenhouse, Microsoft’s VP of technology policy. In addition to releasing more spectrum, the rule will enable “dynamic spectrum sharing that is particularly well suited for absorbing growing wireless data traffic,” he says.

“Cisco Systems estimates that mobile data traffic will grow by a factor of 18 by 2016, and Bell Labs predicts it will increase by a factor of 25,” notes the article. “Many more airwaves could eventually be shared with the help of cognitive radios, which sense available frequencies and shift between them.”

The rule applies to spectrum in the 3.550 to 3.650 gigahertz band, which is currently used by radar systems. At first, the “checked-out” spectrum might be free, but a pricing system may eventually be implemented to allow a wireless carrier to pay for priority access in times of extreme high demand.

“Whatever the details, the move spells the beginning of the end of a system in which spectrum is either exclusively owned by a private company, walled off for government and military use, or unlicensed and crowded,” suggests the article.
