WiMAX - WiMAX Introduction

WiMax is new technology in mobile computing. It is yet to be deployed on huge scale world wide unlike technologies like WiFi etc. WiMax is short form of Worldwide Interoperability of Microwave Access. It performs about similar to some extend like Wifi but at higher speed, at great distance and for greater number of users WiMax operates on 802.16 standards define by IEEE, Institute of Electric and Electronic Engineering. IEEE 802.16 standard is known to be WMAN, Wireless Metropolitan Area Network.

WiMAX technology was developed in earlier 2000 and it was named by WiMax Forums. In year 2004 this technology started to groom and eventually gets into lots of talk’s and  discussions around the world among major international institutes, in year 2004 advancements, enhancements were deployed to some extend. As mentioned above WiMAX has not yet deployed to its full potential and still lot and lots of room to use this technology to its potential. It is not yet put to use as commercialized technologies like Wifi, GPRS, and 3G.

WiMax technology and its potential advancements are recently realized. Using WiMax technology broadband access can be provided to more rural and urban areas where internet can not be provided by other sources like fiber optics or by other regular telephonic cables. There are so many plus points of this technology out of which one is range, it ranges starts from minimum 30 miles, if we look in past, about 30 feet wireless connectivity is provided by Wifi technology. WiMax range depends upon connectivity, if the connection is with Line of Sight (LoS) it can increase from up to 75 miles. WiMAX offers a solution called “Last mile” it can be used as alternative of cable and DSL internet access.

WiMAX can provide data rate up to 70Mbps from larger distances which be can be reached up 30 miles. WiMax operates on two frequencies. IEEE 802 is very flexible standard and provides standard addresses frequencies ranges from 10 GHz to 66 GHz. IEEE 802.16 standard frequency stats that it will also support low latency applications like internet, video, voice all together.

WiMAX technology is quite new, therefore few vendors are trying to develop infrastucture to develop the technology. Vendors like Intel and Fujtsu are leading providers for WiMax Chipset, chip is called SoC. Customer premise equipment (CPE) are manufactured by using these WiMax chips SoCs, this enable the equipment to access WiMAX base station or Wireless Broadband Access (WPA).
