16e vs 16m-difference between WiMAX and WiMAX advanced

This page compares Mobile WiMAX(802.16e) vs WiMAX Advanced(802.16m) and describes difference between WiMAX(16e) and WiMAX Advanced(16m). The useful links to difference between various terms are provided here.

WiMAX standards have been specified in IEEE 802.16 series. IEEE standard specifies wimax PHY and MAC layer specifications. There are various versions of the wimax. The popular among them are fixed wimax(16d), mobile wimax(16e) and wimax advanced(16m).


The standard IEEE 802.16e is referred as mobile wimax standard. It is developed to provide broadband internet connectivity in mobile subscriber devices moving at the pedestrian and vehicular speeds. It uses OFDMA modulation scheme in the downlink and SC-FDMA modulation in the uplink. The frame structure follows TDD topology in which both downlink and uplink share the same frequencies at different time intervals.

There is a concept of zone in mobile wimax in the frame structure. Various zones are supported such as PUSC, FUSC and AMC2X3 depending upon subcarrier assignments in a frame. Refer 802.16e article.

WiMAX Advanced-802.16m

This standard version is amendment to existing 802.16-2009 standard. It has been developed to meet the requirement of IMT-Advanced system. The system has basic applications such as voice,gaming and mobile internet.

The requirement of IMT advanced system as are as follows:
• Max. data rate of about 1GBPS under low mobility scenario.
• Support for 100MHz bandwidth and 10ms round trip time.

To achieve above mentioned requirement of IMT-Advanced 802.16m has been introduced with following features. These will increase the data rates.
• MIMO support with increase in number of antennas
• Multi-carrier operation
• super-frame structure

Following table mentions major difference between WiMAX(16e) and WiMAX Advanced(16m) technologies. One can also read page on 16d vs 16e for difference between 16d and 16e.
