How are WiMAX and Mobile WiMAX related in the evolutionary history of WiMAX?
WiMAX is not a single technology; it is a family of interoperable technologies. In 2001, the original specification, IEEE 802.16, was completed and intended primarily for telecom backhaul applications in point-to-point line-of-sight configurations using spectrum above 10 GHz. This original version of IEEE 802.16 uses a radio interface based on a single-carrier waveform.
