The Future of IoT Depends on ‘Software Defined Radio’

In 1992, Dr. Joseph Mitola proposed taking a "software intensive approach" to radio spectrum. Prior to this, spectrum allocation was viewed as "real estate" to be parceled out (or sold via auctions to the highest bidder), and radios operated on whatever frequency they were assigned. But since the early 90s, software defined radio (SDR)—sometimes called cognitive radio (it’s ALIVE!)—has automatically detected available spectrum and switched frequencies when needed. This will become increasingly important as more and more IoT devices come online; 20.4 billion by 2020, according to Gartner . Add to that the growth of military and commercial drones […]
