WiMAX Wireless Broadband Info

[Md. Mir Hossain]

WiMAX stands for World Interoperability for Microwave Access that enables the   actual broadband wireless network with high speed. WiMAX operate same like WiFi but WiFi operate with some limitation like it is base band technology and cover only 100 feet radius with slow speed. WiMAX covers a radius of 50 Km and work with the speed of 70 Mbps. WiMAX is the replacement of the wired broadband. In wired broadband connection,  we can transmit data with 512 Kbps to 10 Mbps speed and more, for example DSL broadband and cable broadband. In future all new desktop and notebook computers will be   incorporated with  WiMAX technology. With this technology you will be connected to the internet even you are driving your car with the speed of 120 Km.

Objective of WiMAX

    *  Superior Performance
    *  Flexibility
    *  Advanced IP-Based Architecture
    *  Attractive Economics

IEEE 802.16 Specifications

    * Range 30 mile radius from the base station for LOS (line-of-sight).
    * Range 4-6 miles radius from the base station for NLOS (Non-line-of-sight)
    * Maximum data speed supported as 70 Mbps.
    *  Licensed frequency band: 2- 11 GHz
    *  Un-licensed frequency band: 10- 66 GHz
    *  Line of sight is not needed between user and the base station unless very high date rates are required at the user premises.
