Wimax is basically an advancement of IEEE 802.16 standards for broadband wireless access (BWA) networks. Wimax is a benchmark solution for wireless Wide Area Network (WAN).WiMax is a second-generation protocol that allow for more efficient bandwidth use, interference avoidance, and is intended to allow higher data rates over longer distances.
Important components required for Wimax connection are:
* a base station which sends signals
* a Wimax hub for distribution of data
* access points or nodes ( computers ) and
* Wimax enabled devices like laptops, mobiles or Wi-Fi hotspot.
Wimax implementation is challenging as it is basically related with sending signals via air. Hackers or intruders are more likely to attack such networks. Another main challenge that must be faced by Wimax is about the choice of duplexing. It can be TDD (Time Division Duplexing) or FDD (Frequency Division Duplexing) . If it is a FDD structure, then two simultaneously operating complete radios must be required. Another choice could be TDD which requires only one radio and is cost effective too. Some European countries are generally following FDD technology.
Pakistan has a largest fully functional wimax network A telecom company Wateen Telecom installed the network throughout Pakistan using Motorola hardware.
There are many companies worldwide working for the promotion of Wimax technology. In May 2008, major companies like Intel, Google, Comcast and Bright House Networks jointly invest $3.2 billion dollars and works together on a project to create a new mobile broadband company by combining their Wimax business.
Wimax technology is an emerging technology in India and its future is bright in India. Although it is able to provide only fixed broadband connection, still according to recent studies, it is estimated that 6.9 million mobile and fixed Wimax connections would be there by the end of 2008. Wimax is the technology which is responsible for taking telecommunication technology to rural India. As we all know that India is fastest growing mobile market in the world and 7 millions subscribers are adding every month to the connectivity.
The biggest market for WiMAX is in China, where IEEE and the Chinese government are already in discussion to make WiMAX the national standard for fixed broadband wireless access at 3.5 GHz.
The expansion of Wimax technology can be estimated from the fact that the latest laptop Centrino from Intel is equipped with all the necessary requirements for Wimax and hence Intel is promoting Wimax indirectly.
