The wireless network uses radio waves instead of wires to transfer data between computers. To do this:

The Binary code: 1 and 0

It is well known that computers transmit digital information, using binary: ones and zeros. This translates well to radio waves, from 1 and 0 can be represented by different types of beeps. These beeps are so fast they are out of earshot of people.

Morse Code: Dots And Dashes

It works like Morse code, which is a way to communicate with the alphabet over radio waves using dots (short beeps) and dashes (long beeps). Morse code was used manually for years via telegraph to get information on one place to another very quickly. More importantly, in this example, even if it is a binary system, just as the computer system.
wireless network, then we can think of Morse code for computers. Connecting a combined radio transmitter and receiver, and the computer can send the corresponding points, and dashes (bits, computer-speak) so you can get information about this out there.

Wavelengths And Frequencies

One might ask how the computer can send and receive data at high speeds without being messed up nonsense. The key to the wireless network as it gets to this problem.

First, wireless transmissions are sent at very high frequencies, allowing more data sent per second. Most wireless connections use a frequency of 2.4 gigahertz (2.4 billion cycles per second) - a frequency similar to mobile phones and microwave ovens. However, this high frequency produces a very short wavelength, so that wireless networking only works over short distances.

Wireless networks also use a technique called frequency hopping. "They use dozens of frequencies, and constantly switch between them. This makes wireless networks more immune to interference from other radio signals if transmitted in a single frequency.

Internet Access Points

The final step to a wireless network to provide Internet access for each computer on the network. This is done using a special piece of equipment called a wireless access point. An access point is more expensive than a wireless card to a computer, which contains radio capable of communicating with nearly 100 computers, sharing internet access among them. Dedicated access points are necessary only for larger networks. With only a few computers, you can use one as an access point or using a wireless router.

Industry Standards

wireless equipment from different vendors can work together to handle these complex communications because there are standards governing the production of all wireless devices. These standards are technically known as 802.11. Because of the industry to meet these standards, wireless networking is both easy to use and affordable today.

Wireless Is Simple To Use

If all these stories of frequencies has you worried - relax. Wireless networking hardware and software handle all this automatically, without user intervention. Wireless networks, for all complexes of its capacity is much simpler to use than you might expect.
