Years ago, a wireless was a radio. Now, having a wireless doesn’t mean you sit around listening to a box and trying to imagine pictures. It means wireless internet.

One of the most popular and well known wireless technology standards is Wi-Fi (Wireless Fidelity), which allows users to access the internet over a wireless Local Area Network. The speed and range of Wi-Fi, however, is severely limited. There is another wireless connectivity standard, called WiMAX, which is considerably more advanced.

WiMAX is a protocol by which signals are sent to wireless broadband users. A WiMAX base station can theoretically beam a signal as far as 50km (31 miles), meaning that a single station could potentially cover an entire city (unlike Wi-Fi, which is only available in “hotspots”).

Wireless broadband can be seen as an extension of standard broadband. The provider sets up your regular service through your phone line, but also sets you up for access at special WiFi points outside the home. Similar idea to an internet caf, except you can use your own laptop and settings, and you can find them in places like motorway service stations, airports, train stations, and any other places that travellers frequent.

Although WiMAX has been a major technological achievement, wireless broadband certainly doesn’t stop there. There are a number of other cutting edge wireless protocols currently in development. The most notable of these is a new protocol called xMax, which is similar to WiMAX, but a lot more efficient. It can cover a broader range at a lower cost, by piggybacking on radio frequencies. Although xMax is not yet available to the public, it will most likely be launched within the next couple of years.
