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 was a superior technology in terms of speed (roughly 25 Mbit/s) for a few years (2005-2009), and it pioneered some new technologies such as MIMO. But the mobile version of WiMax (802.16m), intended to compete with GSM and CDMA technologies, was too little/too late in getting established, and by the time the LTE standard was finalized in ...
[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 ...
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 Superseded [2] 802.16-2012 IEEE Standard for Air Interface for Broadband Wireless Access Systems It is a rollup of 802.16h, 802.16j and Std 802.16m
Notes: All speeds are theoretical maximums and will vary by a number of factors, including the use of external antennas, distance from the tower and the ground speed (e.g. communications on a train may be poorer than when standing still).
2G (or 2-G) provides three primary benefits over their predecessors: phone conversations are digitally encrypted; 2G systems are significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS (Short Message Service) plain text-based messages. 2G technologies enable the various mobile phone ...
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.
