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.
Institute of Electrical and Electronics (IEEE) is developing the standardization of 802.16 / m, which is the latest version of the standardization of IEEE 802.16 (Wimax). This standardization development began in March 2007 and planned for completion by the end of 2009. Created with the aim to increase data transfer speed reaches 1 Gbps in quiet conditions and 100 Mbps on the condition of moving (mobile). Standardization 802.16 / m harmony with the requirements of the International Telecommunication Union (ITU) for the development of 4G technology. IEEE to develop a competitive radio access technology and has a significant advantage ("Gigabit Wimax") and be able to compete with ITU R / IMT Advanched. MIMO technology (Multiple In / Multiple Out) and a meruapakan SOFDMA modulasimulticarrier technique that uses subchanelisasi also be the basis for development of this standard.
Development of Wireless Broadband
Success in Wireline Broadband (Cable / DSL) and Wi-Fi Mobile Broadband impacted by the emergence of the Internet, and coupled with increasing demand. Consumers need a mobile internet, which has the ability to access the Internet anywhere and anytime. Therefore we need a standardization for mobile internet technologies, and also needed an IP-based wireless broadband network that has a quality similar to wireline broadband mobility with additional capabilities. In other words, it takes a mobile broadband technology in accordance with the requirements of mobile Internet. IEEE 802.16 answered those needs by developing 802.16 / m. The features found on 802.16 / m mobile wimax as contained in the following table:
802.16 / m is one of the candidates for IMT-Advanced Evaluation Process and also a New Advanced Water Interface that operates in licensed bands. Candidate other 4G technologies are considered for Long Term Evolution (LTE), and ultramobile broadband (UMB). The difference from a few candidate technologiessuch as the following:
Designed by 3GPP LTE, the developer of 3G from the group GSM. Proposed by the 3GPP2 UMB, development CDMA2000, and WiMAX II, or 802.16 / m by wimax forums. At first, IMT – Advanced Next Generation Mobile Network using a standard M-2072, which then 802.16-2004 replaced with, and 802.16e. 802.16 / m represents the next development of standardization 802.16 / e.
In IEEE 802.16 / m there is one and mobile wimax releases
mobile wimax release 2. The difference between R1 and R2
