President Obama will unveil his Wireless Innovation and Infrastructure Initiative in a speech today (Feb. 9) at Northern Michigan University at Marquette, reports National Journal. The speech backs the idea of a voluntary spectrum giveback that could net the government a total of $27.8 billion over the next 10 years, $9.6 billion of which would go to deficit reductions, White House officials said. Those figures are estimates of what the government would have after giving broadcasters and others who relinquish spectrum a share in auction proceeds, and paying the costs of relocating or consolidating spectrum users into different bands.
