The 802.16m mobile WiMAX standard is a follow-on to 802.16e standard and is a candidate to the International Telecom Union's (ITU) consideration as an IMT advanced (4G) technology - specifically, providing downlink speeds of at least 100 Mbps in a wide area with high-mobility.

The new 802.16m standard will provide increased performance advantages over 802.16e.   From a technological perspective, 802.16m is capable of providing up to 120 Mbps down and 60 Mbps up in an urban setting, using 4x2 MIMO antennas on a single 20MHz-wide channel.   Even higher data rates can be achieved with additional spectrum resources or more complex antenna schemes.   Actual commercial performance will be considerably less based on spectrum used and other factors.

While 802.16m will provide increased performance for users, the main, driving factor for operators adopting the technology will be increased network capacity to accommodate the massive bandwidth increases driven by smartphones, tablets and other wireless devices.

In addition to capacity and performance advantages, 802.16m will be backward compatible with existing WiMAX networks, providing ease-of-mind for operators deploying networks today.   Most mobile WiMAX operators can easily convert from 802.16e to 802.16m by updating some circuit plate units and software in their bases stations.
