What is the technology behind wireless broadband services?
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 is 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").
Although WiMAX are networks are available in several major metropolitan areas in the US, base stations are very expensive to build, and aren t cost effective in less densely populated areas. Because of this limitation, WiMAX technology is not yet available in most non-urban regions.
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.
