This frequency range has been set aside by the FCC, and is generally labeled the ISM (Industrial, Scientific and Medical) band. A few years ago Apple and several other large corporations requested that the FCC allow the development of wireless networks within this frequency range. What we have today is a protocol and system that allows for unlicensed use of radios within a prescribed power level. The ISM band is populated by Industrial, Scientific and Medical devices that are all low power devices.
