A coalition of broadcasters, wireless providers, and chip makers Thursday urged the FCC to adopt guidelines to minimize potential conflict between broadcasters and wireless companies as the agency strives to cope with rising stress on bandwidth. Because of ever-increasing demand for mobile devices, the FCC proposed in September that broadcasters voluntarily give up some of their allotted bandwidth in exchange for a share of the proceeds when that bandwidth is auctioned to wireless broadband providers. The National Association of Broadcasters initially worried that broadcasters in smaller markets would be more likely to give up spectrum than those in urban markets. But it has turned out that a number of broadcasters in larger markets are willing to sell spectrum rights. Coalition goals cover a range of technical issues that are intended to protect TV and wireless signals against interference from each other and for minimum and maximum size specifications for individual segments of spectrum. The coalition also specifically calls for the FCC to expedite spectrum coordination with Canada and Mexico. In addition to NAB coalition members include Intel, AT&T, Verizon, T-Mobile and Qualcomm.
