The reason for this hot and heavy battle has to do with the low-band 600MHz spectrum. Such low-band airwaves can travel for longer distances than higher band spectrum, and can more easily penetrate buildings. Verizon and AT&T control 74% of such low-band spectrum, while Sprint owns 12% and 2% belongs to T-Mobile.
AT&T's vice president of federal regulatory, Joan Marsh, wrote on the company blog on Wednesday that T-Mobile and Sprint should not be worried. Besides trying to persuade the FCC not to impose a cap on how much spectrum can be won by one carrier, AT&T does not want the government to set aside some of the valuable spectrum for smaller companies. Marsh wrote that based on the winning bids from the last auction, it would take $20 to 30 billion for one carrier to dominate the upcoming auction. The executive says that this is too high a price tag for one, or even two companies, to pay. As for the "set-aside," she says that holding spectrum for smaller carriers would only force AT&T and Verizon to bid against each other for a smaller amount of spectrum, raising costs in the industry. That could eventually lead to higher prices for consumers to pay for cellular service. She also wrote that by adding a cap on the amount of spectrum that can be won in the auction, the FCC would actually be minimizing the amount of revenue being raised by the government.
Kathleen Ham, vice president of federal regulatory affairs at T-Mobile, responded to Marsh's post by writing that only an auction with multiple bidders of every size will result in a competitive industry that benefits consumers. She added that AT&T continues to repeat the same message, which is that "sacrificing competition for duopoly is good public policy."
The FCC has a very tough decision ahead. No matter which way it decides, two carriers are going to feel like losers even before the auction starts.
