Detailed explanation-1: -Explanation: WiMAX supports a variety of modulation schemes such as binary phase shift keying modulation, quadrature phase shift keying modulation, and quadrature amplitude modulation and allows for the scheme to change on a burst-by-burst basis per link, depending on channel conditions.
Detailed explanation-2: -The WiMAX physical layer (PHY) is based on orthogonal frequency division multiplexing, a scheme that offers good resistance to multipath, and allows WiMAX to operate in NLOS conditions.
Detailed explanation-3: -WiMax comprises of a tower and a receiver holding a remote station, Connectivity Service Station, and Access Service Network.
Detailed explanation-4: -Worldwide Interoperability for Microwave Access (WiMAX) is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide physical layer (PHY) and media access control (MAC) options.
