WiMAX is the worldwide interoperability for microwave access, to provide business and consumer world wireless broad band services in metropolitan area networks. It has a target range of 31 miles and a target transmission rate exceeding 100 Mbps. Mobile WiMAX is an OFDM based technology for deployment which allows multiple-antenna operations to be performed on vector-flat sub carrier. Fixed WiMAX, which is based on IEEE 802.16-2004, uses a 256 FFT- based OFDM physical layer. Mobile WiMAX, which is based on the IEEE 802.16e-2005 standard, uses a scalable OFDM-based physical layer. It integrates wireless technology specific functionally with IP networking equipment.
