The IEEE 802.16 standard, including MAC layer and PHY layer specifications which defines the air interface and associated functions of the broadband wireless access system supporting multimedia services.IEEE802.16 (i.e. WIMAX) is designed basically for high range and high bandwidth wireless access, or Wireless Metropolitan Area Network (WMAN). The WIMAX having high bandwidth of 70 Mbps and radio range can access up to 50 km (31 miles). WIMAX provides multiple services with guaranteed different QoS. It is cost effective and as well as alternative idea to replace other network such as Wi-Fi and 3G/4G and easy to deploy for large miles (distance) access to public network.
