Mobile WiMAX 802.16 / m is the 'air interface' which offers a new spectrum efficiency and throughput in accordance with the requirements of ITU for 4G technology development kedepannnya. IEEE 802.16 / m is to standardize data transmission speed is higher on mobile devices. Data speeds up to 1Gbps and possible distribution via wireless broadband access is an alternative to cable, DSL, and 3G. Broadband spectrum that is used in the frequency range from 2.3 GHz-3.5 GHz and the use of OFDM / OFDMA (Orthogonal Frequency Division Multiplexing Access). With the use of OFDM / OFDMA is considered to bring efficiency gains in terms of frequency bandwidth, coverage areas, installation and cost. Development by the IEEE 802.16 standardization began in March 2007 and scheduled for completion around the year 2009.
