Most Federal Communications Commission commissioners have voted to support the Consensus Plan proposal, but Nextel Communications will have to pay $1.3 billion to $1.5 billion more than it proposed in exchange for spectrum at 1.9 GHz, the Washington Post reported today.

Under the Consensus Plan, Nextel had agreed to pay $850 million to fund rebanding in the 800 MHz frequencies, which is designed to alleviate interference problems between cellular carriers and public-safety radio systems. Nextel did not propose to pay any additional money for the 1.9 GHz spectrum, but other commercial wireless operators have said such a deal would be a windfall to Nextel and that the FCC is legally obligated to auction the airwaves.
