Wireless broadband is a general term used for the technology that is able to gain access to the internet wirelessly, and at high bandwidth speeds. Wireless broadband is available on virtually any digital device, so long as it has the proper connectivity hardware. Such hardware can easily be attached to most PDAs and laptop computers.
Wireless broadband works by using short-range radio waves to create a small area where your computers can be networked without wires - most wireless networks are no bigger than a house, although larger ones are possible.
In a Wireless network (WiFi) the computers within it can communicate with each other, and a password is set to prevent outside connection and interference. Firewalls are essential, and fortunately they are standard with most wireless routers. A network card fitted to every computer within the network is necessary too, and again, they’re usually standard in most newer PC’s and laptops. If one PC in your house doesn’t have a network card, it can still be connected to the WiFi network by means of cables.
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.
