The National Telecommunications and Information Administration (NTIA), a department of the U.S. Department of Commerce, has issued a report, which clears the way for the US's proposed large-scale auction of wireless spectrum. According to the report the cost of transitioning government users out of 1710-1755 MHz spectrum will be about $935 million. The government expects to recover this cost through the auction. Wireless operators, which can bid for the spectrum in an auction, are either waiting for it in order to be able to launch 3G services or are interested in it as a way to expand their already launched 3G services.
