A few days ago, the big news in the telecom world was that President Obama again ordered federal agencies to share and sell their spectrum to expand commercial mobile broadband use. This effort is premised on the fact that agencies use their gifted airwaves poorly while demand for mobile broadband is surging. While the presidential memorandum half-heartedly supports clearing out agencies from some bands and selling it off, the focus of the memo is shared access, whereby federal agencies agree to allow non-federal users to use the same spectrum bands with non-interfering technologies.
The good news is that there is no mention of PCAST’s 2012 recommendation to the president to create a 1000 MHz “superhighway” of unlicensed federal spectrum accessed by sensing devices. This radical proposal would replace the conventional clearing-and-auction process with a spectrum commons framework reliant on unproven sensing technologies. Instead of consumers relying on carriers’ spectrum for mobile broadband, this plan would crudely imitate (in theory) wifi on steroids, where devices would search out access over a huge portion of valuable spectrum, avoiding federal users. Its omission in the recent memo likely means the unlicensed superhighway won’t be pursued.
Still, this doubling-down on other forms of dynamic spectrum sharing is unfortunate for several reasons. Continue reading →
