Spectrum reallocation
In the United States, spectrum reallocation mostly refers to the giving up part of the broadcast spectrum to make more room for wireless broadband, trunking or point to point microwave services.Spectrum reallocation is being done partly through auctions authorized by Title VI (The Spectrum Act) of the payroll tax cut extension passed by Congress on February 17, 2012. Many broadcasters oppose this plan, even though they have been assured stations will not be forced off the air.
