On Wednesday, FCC Chairman Julius Genachowski debunked various arguments against the FCC’s planned use of incentive auctions for relocating 120 MHz of broadcast TV spectrum to the wireless industry, as he affirmed that the FCC had finished work on a “baseline spectrum inventory that tells us more than enough to conclude that incentive auctions are . . . essential.” In a speech at a Washington, D.C. policy forum sponsored by Mobile Future, Genachowski addressed complaints, articulated by broadcasters and others, that (1) wireless carriers have been hoarding spectrum, (2) warnings of an impending wireless spectrum shortage are exaggerated, and (3) broadcasters will be adversely affected by the realignment of television spectrum in the wake of the incentive auction process. Citing expert projections that, by 2014, demand for mobile broadband and the spectrum needed to support such services “will be 35 times the levels it was in 2009,” Genachowski declared that “the looming spectrum shortage is real—and it is the alleged hoarding that is illusory.” Genachowski also argued against suggestions that the FCC should forego incentive auctions and instead allow broadcasters to sub-lease their spectrum to wireless carriers, asserting that sub-leasing “won’t free up contiguous blocks of spectrum over broad geographic areas which is what’s needed for mobile broadband.” With respect to channel realignment, Genachowski acknowledged the concerns of broadcasters as he noted that the FCC’s plan would “seek to minimize the number of stations affected.” Genachowski further noted that “broadcasters’ efforts to become multiplatform programming entities should be encouraged, and we should work together to remove barriers to such efforts.” Voicing appreciation for Genachowski’s admission that “hundreds of broadcasters are developing new and creative business models on multiple platforms to serve millions of viewers,” National Association of Broadcasters CEO Gordon Smith voiced hope that the FCC will undertake “a thoughtful process that in no way jeopardizes the digital promise that was made to 43 million Americans who rely exclusively on . . . programming offered by free and local broadcasters.”
