WiMAX

WiMAX(Worldwide Interoperability for Microwave Access), is a technology that can potentially revolutionize the way internet is being accessed. Wi max can be used for mobile internet and offers high speed,wireless access to the internet anywhere within the WiMAX network. It provides a uplink speed of 35 mbps and downlink speed of 144 mbps. The cost of using wi max is cheaper than the USB internet that uses the EDGE or the EVDO technology.But on the other hand the initial cost of installing wi-max networks is huge.Wi-max has just made its mark in India. Recently companies in India like TATA BSNL and Reliance have made investments to create wi-max networks in India.A problem with WiMAX is that it is prone to interference with frequency bands that are used for ground to satellite communication when common channels are used for both.Tests have also found that WiMAX can deliver only one of the two promised advantages,high bitrates over large distances.The bit error rate ncreases as distance is more leading to lower bitrates but the bitrate becomes high if the distance is reduced.There are two sides to a coin.. and despite all the cons, the advantages are plenty in using WiMAX and all indcations point to WiMAX replacing other wireless technologies in the future if companies are willing to invest in it.
