This paper gives an overview about the various PHY and MAC layer specification which define the IEEE 802.16 standard and which define the Fixed WiMAX (Ver. 802.16d-2004) and Mobile WiMAX (Ver. 802.16e-2005) network scenarios. We also discuss about the various updates in the Advanced Air Interface update (802.16m – 2011), which aims at fulfilling the 4G requirements as put forward by the ITU IMT-Advanced requirements.
