White Space refers to portions of licensed wireless spectrum that are designated as buffers between channels, for example, buffers between channels used for TV broadcasting. White Space, although is part of licensed wireless spectrum, can be redeployed for unlicensed use in areas where it is not actually used for the licensed service.  

The redeployment of White Space is expected to help meet the demand for spectrum in rural broadband, city-wide data networks, campus/hospital data networks and machine-to-machine communications.
