What is clear with WiMAX?

WiMAX technology is one of the broadband wireless access (BWA) such as WiFi has a data transfer speeds higher (Max 75 Mbps) and reach a wider (Max 50 Km). WiMAX BWA is a technology based on the IEEE 802.16 standard. There are several technologies that support the WiMAX have the data rate and coverage of the BWA better than the others, namely technology, OFDM, OFDMA, SOFDMA, Smart antenna, power control, FEC, adaptive Modulation.

IEEE remove some of the WiMAX standard. The first is the IEEE 802.16 working at a frequency of 10-66 GHz. Standard is used only for the condition of LOS (Line of Sight) and regular communication is implemented for PTP (point to point). Standard IEEE 802.16a is the next dikeluaran that in 2003 the work at a frequency of 2-11 GHz and using OFDM technology so that it can be used for the NLOS conditions. Then issued a standard IEEE 802.16e Rev 2004 issued in 2004. On this standard OFDMA technology is used, also works at a frequency of 2-11 GHz. On this standard also allows the use for NLOS conditions and have the ability portable (not mobile). Development is the latest standard IEEE 802.16e 2005 working at a frequency of 2-6 GHz and the ability to have mobile. In the standard technology used to support the SOFDMA flexibility in dealing with government regulations and kebuthan service.

WiMAS predicted will dominate the market due to feature the broadband promise. WiMAX can be a competitor of 3G or mutual support to one another. The implementation of WiMAX are:
1. cellular backhoul
2. WiFi backhoul
3. Public safety
4. Banking
5. Other
