The Pentagon issued a request for information on innovative spectrum sharing solutions " to understand both the art of the possible, as well as current industry trends in spectrum utilization."

Under the first three solicitations released so far, work will take place at Marine Corps Logistics Base Albany, Georgia; Joint Base Lewis-McChord in Washington; and Naval Base San Diego, California.

Four companies spent over 97 percent of the total amount raised in the AWS-3 spectrum auction, which closed Thursday.

The result of the AWS-3 auction set a record for the FCC and nicely sets up the forthcoming broadcast spectrum auction.

The FCC commissioner says more unlicensed spectrum will only help foster innovation and add to the billions of dollars in economic activity that takes place wirelessly.
