Where’s all this spectrum going to come from?
[Commentary] Predictably, spectrum was a hot topic at the Phoenix Center’s excellent policy symposium.
Blair Levin, the architect of the National Broadband Plan, was one of the speakers, and the Plan’s forecast for 500 MHz of new spectrum was reiterated by the speakers on the spectrum panel.
The issue has changed quite a lot since the Broadband Plan was written. Subsequent developments highlight the need for spectrum for non-Internet uses such as Medical Body Area Networks, car safety and navigation, and drones. Government is making small steps to reduce its spectrum footprint, but there’s no question that demand is growing much faster than supply and will continue to grow at the speed of imagination. So part of the problem is that we have three models of spectrum allocation (licensed, unlicensed, and dynamic), one of which is dysfunctional in the current state of technology. What would it take to make White Spaces and other dynamic spectrum allocation systems work? That’s the $64 billion question, but there’s a theoretical answer: technical systems that allow multiple transmissions at the same time, place, direction, and frequency without detectable interference.
