Wireless Networks: How Do They Work

Summary:

Wireless networking can be thought of as Morse code for computers.For all its complicated ability, is far simpler to use than you might expect.

Article Body:

Wireless networks use radio waves instead of wires to transmit data between computers. Here's how:

The Binary Code: 1s and 0s

It is well known that computers transmit information digitally through binary code: digital and zero. It translates well to radio waves because these 1s and 0s can be represented by different types of signals. These signals are so fast that they cannot exceed human hearing.

Morse Code: Dots And Dashes

It works like Morse code, a way to transmit the alphabet to radio waves using dots (short beeps) and dashes (long beeps). Morse code has been used for many years to manually transfer information from one place to another via the telegraph. More important for this example, though, is a binary system, like a computer system.

Wavelengths And Frequencies

You'd be surprised how fast computers can send and receive data. The key to wireless networking is how it solves this problem.

First, wireless transmissions are sent at very high frequencies, allowing more data to be sent per second. Most wireless connections use 2.4 GHz (2.4 billion cycles per second), a frequency similar to cell phones and microwave ovens. However, this high frequency produces a very short wavelength, so wireless networking is only effective over short distances.

Wireless networks also use the so-called "frequency cut" method. They use dozens of frequencies and switch between them regularly. This protects wireless networks from interfering with other radio signals if sent at the same frequency.

Internet Access Points

The final step in a wireless network is to provide Internet access to all the computers on the network. This is done by a special wireless device called an access point. Anaccess point is It is more expensive than a wireless card for 1 computer because it includes radios capable of communicating with about 100 computers and accessing the Internet between them. Dedicated access points are only needed for large systems. With only a few computers, 1 of them can be used as an access point or a wireless router.

Industry Standards

Wireless devices from different manufacturers can work together to manage these complex communications, as there are standards governing the production of all wireless devices. These standards are technically called 802.11. Because the industry meets these standards, wireless communication is now easy to use and affordable.

Wireless Is Simple To Use

If this frequency talk worries you - relax. Wireless networking equipment and software use all of this automatically, without the need for user interference. The wireless network, for all its complex capabilities, is easier than you expect.
