Understanding the kaleidoscope of unlicensed spectrum
These are exciting times for those trying to comprehend the whirlwind of expansion coming to unlicensed spectrum bands. The simple shared access model employed today in the unlicensed Industrial, Scientific and Medical (ISM) bands will not be a sufficient model when new targeted licensed bands start sharing their bandwidth. Not all bands can be treated equally; at least not from a policy perspective. A wide range of policies and restrictions will be forthcoming which will impact how, where, and when these new shared spectrum bands can be used and by whom. This white paper offers a brief overview of the situation and speculates on where it is likely headed.
