Free the Radio Spectrum
[Commentary] It's time to rethink the way we allocate spectrum.
Today radios that can share spectrum make such protections from interference unnecessary. Just as car drivers can change lanes to avoid congestion, these "smart radios," also called "cognitive radios," are transceivers that listen to available frequencies and communicate over any channels that are currently unused. These radios not only shift frequencies but can also be programmed with the necessary protocols for use in different bands, such as for speaking the "language" of various blocks of spectrum used for Wi-Fi, television, or cellphones. This means that vast swaths of spectrum no longer need be locked into single use, or left unused, as a hedge against interference.
Unfortunately, the Federal Communications Commission's policies still assume the use of antiquated technology, and therefore that license holders must maintain absolute control of spectrum space at all times. These regulations must be updated to reflect the technological realities of smart radios.
