What is WiMAX

WiMAX is a wireless technology that optimizes IP centric services to a large area and a certification mark for devices conform to the IEEE 802.16 WiMAX also is a platfrom to build an alternative and a complement of broadband networks. In the sense of communication between several WiMAX devices of different vendors can still be made (no proprietary). With the large data rates (up to 70 MBps), WiMAX can be applied for broadband connection 'last mile', or backhaul.

WiMAX development is within the ability of sufficient width. Fixed WiMAX in principle developed from the system WiFi (Wireless Fidelity), so the limitations of WiFi can be equipped with this system, especially in terms of coverage or distance. While the Mobile WiMAX technology was developed to be able to offset the cellular such as GSM, CDMA 2000 and the three-generation or 3G abbreviated. The advantages contained in the Mobile WiMAX system configuration is much simpler as well as data transmission capability is higher.

Therefore the WiMAX system is very possible and easily organized by a new operator or service provider a small scale. Wireless communication network was initially only used for voice communication. Furthermore, wireless communication network developed for data communication, not only in the form of sound. Based on the amount of coverage, the wireless network can be divided into four types. Wireless network based on the size of the coverage area are:

1. Wireless Personal Area Network
The wireless network has a range of less than 10 meters. Usually used for connection equipment for one person. Example: Bluetooth, UWB, Zigbee.
2. Wireless Local Area Network
The wireless network has a range of about 100 meters. Typically used in area that is not too wide, like a house, one floor of the building, and a restaurant. Example: WiFi (Wireless Fidelity).

3. Wireless Metropilitan Area Network
The wireless network has a range of several kilometers. typically used to connect a campus and a small town. Example: WiMAX (Fixed WiMAX).

4. Wide Are Network
The wireless network has a very wide range, which is able to cover the continent. Example: 3G (three generation) and WiMAX (Mobile WiMAX).
