It is a PTP and PMP wireless technology which is based on IEEE 802.16 standard. WiMAX is a wireless technology that supports high speed data service, video and voice at the customer side. WiMAX technology could be used to overcome the problems like less coverage area, low data rate and less security. WiMAX technology has various versions that are 802.16d (fixed WiMAX) and 802.16e (mobile WiMAX). OFDM is an amalgam of multiplexing and modulation.
