To hear some of its more enthusiastic proponents you might conclude that WiMax, an emerging wireless-broadband technology, was about to take over the world. WiMax is akin to a long-range version of the popular Wi-Fi technology that allows computers close to a small base-station to surf the internet without wires. Whereas Wi-Fi’s range is limited to a few tens of metres, WiMax can, in theory, work over tens of kilometres, allowing huge areas to be blanketed with wireless coverage. Hence the claims that WiMax will bring internet access to the 5 billion people who currently lack it, or that it will render expensive “third-generation†(3G) mobile networks redundant.
