WiMAX MIMO refers to the use of Multiple-input multiple-output communications (MIMO) technology on WiMAX, which is the technology brand name for the implementation of the standard IEEE 802.16. Background
WiMAX release 2.1, popularly branded as WiMAX 2+, is a backwards-compatible transition from previous WiMAX generations. It is compatible and interoperable with TD-LTE . Newer versions, still backward compatible, include WiMAX release 2.2 (2014) and WiMAX release 3 (2021, adds interoperation with 5G NR ).
[1] [2] MIMO has become an essential element of wireless communication standards including IEEE 802.11n (Wi-Fi 4), IEEE 802.11ac (Wi-Fi 5), HSPA+ (3G), WiMAX, and Long Term Evolution (LTE). More recently, MIMO has been applied to power-line communication for three-wire installations as part of the ITU G.hn standard and of the HomePlug AV2 ...
OFDMA is considered as highly suitable for broadband wireless networks, due to advantages including scalability and use of multiple antennas (MIMO-friendliness), and ability to take advantage of channel frequency selectivity. [1] In spectrum sensing cognitive radio, OFDMA is a possible approach to filling free radio frequency bands adaptively.
Also known as Mobile WiMAX Release 2 or WirelessMAN-Advanced. Aiming at fulfilling the ITU-R IMT-Advanced requirements on 4G systems. Superseded [2] 802.16-2012 IEEE Standard for Air Interface for Broadband Wireless Access Systems It is a rollup of 802.16h, 802.16j and Std 802.16m
IEEE 802.16 - called fixed WiMAX because of static connection without handover.; IEEE 802.16e - called mobile WiMAX because it allows handovers between base stations.; IEEE 802.16m - advanced air interface with data rates of 100 Mbit/s mobile and 1 Gbit/s fixed.
Wi-Fi uses multiple parts of the IEEE 802 protocol family and is designed to work well with its wired sibling, Ethernet. Compatible devices can network through wireless access points with each other as well as with wired devices and the Internet.
