Current wireless broadband technologies have now been providing omnipresent broadband access to wireless subscribers which were only confined to the wire line users till sometime ago. Traditionally, the wireless technologies have been categorized based on their area of coverage. The IEEE 802.11 and ETSI HiperLAN standards are the de facto standards of wireless access in local areas. Whereas IEEE 802.16 and 802.22, ETSI HiperACCESS and HiperMAN, WiBro, and HAP technologies has been predominantly used for providing service in metropolitan and cosmopolitan areas.
There have been many papers written in the recent past covering various types of wireless broadband access technologies, ranging from WLANs to satellite communications. But the study carried out previously never captured the entire spectrum of all such technologies, and even if one particular family of the wireless broadband access technology was scrutinized, the authors somehow concentrated only on certain aspects. In this paper, we aim to bridge that gap by summarizing one of the emerging wireless broadband access technologies i.e. IEEE 802. 16: WiMAX family in detail. Though some of the earliest versions of this family date back to the early decade and some are even out of practice, still we have included them in our study for the sake of completeness and a sense of insight.
