The Wireless Internet
Today's world has really advanced in our ways of transmitting data, and being able to read whatever we like, with just the click of a button. Did you ever stop to think, how is that done, and especially so fast, we went from the pony express, to the U.S mail Service, to Telegraphs, to modern technology.
Wireless internet has many advantages for both business, as well as residential users. Wireless internet provides excellent broadband speeds, Wireless internet is more reliable as compared to internet via cable or satellite. Initial cost to the service provider too are reduced as they do not have to lay out expensive cables or pay highly for satellite tramission., All that is required is the setting up of internet towers, which are very similar to mobile towers., The user will be connected to the internet as long as his laptop device receives a signal from the nearest tower.Let's use the WiMax network, it consist of base stations similar to mobile towers that are set up by service providers, and a receiving antenna, which is similar to a mobile phone antenna at the users end. The user pays the service provider for wireless acess, just as they would for a normalinternet connection via a cable network. The service provider provides the end user with the software for the unit to be WiMax compatible.
The service provider beams the internet signals from the base station. The antenna at the user end catch the signal, providing unintrupted internet as long as the signal is available. With a laptop equipped with an antenna you could be connected to the internet wherever the signal is available from thebase station. Once you move from one base station to another, your laptop receiver will hook up to the other base station of the same provider with a stronger signal.
Wireless internet is not limited to WiMax. Most of us have used some sort of wireless internet some time or the other. GPRS (General Packet Radio Seervice) is one. When a mobile user subscribed to GPRS service, the receiving mobile unit could receive voice as well as data signals. The only downfall, was the speed was very slow. This was replaced by EDGE ( Enhanced Data Rates for Global Evolution) technology.
EDGE was a enhancement overGPRS , able to provide more capacity for voice traffic and at the same time to have high-speed data transfer. 4-G arrived in it's anticipated time frame 2010-2012. Welcome to the world of advanced technology.
