New Technologies Allow More Flexible Use of Spectrum

Upcoming wireless technologies are changing how electromagnetic spectrum is viewed, as well as used. These new radio technologies can use transmit voice and data communications using parts of the spectrum that are unlicensed or underused. One technology from Mississippi-based SIGFX LLC uses a sliver of spectrum already used by TV stations to transmit cell phone calls. The company proposes that the lower costs and increased range of the product could bring reliable communications services to rural areas and developing countries.

Another upcoming technology, software defined radio, lets software determine the function that a device will execute. A user would just click on an icon to change a function from cell phone calling to garage door opening, for example. Other smart radio technologies would be able to sense what part of the spectrum is available and automatically switch to that area to avoid interference. These developments are giving rise to an "open spectrum" movement, and are changing how the Federal Communications Commission views the possibilities for allocating spectrum. Wireless carriers are interested in gaining more flexibility in using and trading the spectrum for which they paid billions. The open spectrum movement supports making available more unlicensed spectrum, as well as increased access to regulated spectrum bands. The ensuing discussions on how spectrum should be used are described as "the most interesting debate in spectrum governance taking place in America since the 1930s." (Source: AP) 

MobileInfo Comments and Advisory:  A scarce resource like radio spectrum needs all the help it can get. While we support an open spectrum and more of it, we urge the research community to figure out how to communicate within a noisy (spectrum) crowd when every one is trying to shout. Can we tune into only the conversation that we want to take part in? That is the challenge. Software models that exchange IDs and tune others out may help.
