The agencies sign a memorandum of understanding intended to increase cooperation and promote more efficient use of spectrum.

As 5G mobile networks mature, everybody from the DOD to commercial companies wants a piece of the spectrum.

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.
