Understanding How Wireless Networks Work

Wireless networks are extremely popular these days. A wireless network is when radio waves instead of cables are used to transmit data between computers. Understanding how these networks work is important for anybody in the web hosting business, more so these days when all sorts of rumors and half-truths are circulating about various new technologies.

Actually transmitting of computer data via radio is very easy because already computer data is usually transmitted digitally. The digital system used is a binary one, meaning that ones and zeros are used. This translates easily and very well into radio waves.

Actually the way it works is quite similar to the legendary Morse Code, used widely during the second world war. So it is in fact all very simple when you think of it in this way. It is just a matter of connecting a radio receiver and transmitter in a computer and the computer will be able to send out and receive digital information.

The fact that wireless transmissions are usually sent at very high frequencies (most use a frequency of 2.4 gigahertz) meaning that a lot of data can be sent every second. However the disadvantage of transmitting in high frequency means that data can only reach within a very small area.

When it comes to computers sharing Internet access, an access point is used. This is a piece of special wireless equipment. Access points are usually very powerful and are capable of exchanging data with 100 other computers at the same time and even sharing out access to the Internet between them.

There is little doubt that wireless networks will continue to be increasingly popular in this country and beyond.
