Wireless networks use radio waves instead of cables for data transfer between computers. Here’s how:
The Binary Code: 1s and 0s
It is known that computers transmit digital information, with the binary: ones and zeros. This also leads to radio waves, since these 1s and 0s can be represented by different tones. These beeps are so fast they are out of earshot of the man.
Morse code dots and dashes
It works like Morse code, a way to transfer the alphabet over radio waves using dots (beeps), and dashes (long beeps). Morse code was manually used for years by the telegraph for information from 1 Place to another go very fast. More importantly for this example, if a binary system, such as a computer system.
The wireless network can then be viewed as a Morse code for computers. They put in a combined radio receiver and transmitter, and the computer is able to send the equivalent of dots and dashes (bits, in computer language), your data from here to there.
The wavelengths and frequencies
One wonders how the computer can send and receive data at high speed without distorted nonsense. The key for wireless networks, as it overcomes this problem.
First, wireless transmissions at very high frequencies, more data can be transmitted per second are sent. 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 wavelength is very short, which is why wireless networking only works over short distances explained.
Wireless networks also a technique called “Frequency Hopping”. You use dozens of frequencies, and constantly switch between them. This makes wireless networks more immune to interference from other radio signals than if they transmitted on a single frequency.
Internet Access Points
The final step to a wireless network is to provide Internet access for each computer on the network. This is done by a special device called a Wireless Access Point. An access point is more expensive than a wireless card for a computer, because it can communicate with radios that contains about 100 computers, sharing Internet access between them. Dedicated access points are required for large networks. With only a few computers it is possible to use one of them as an access point, or use a wireless router.
Industry standards
cooperate wireless devices from different manufacturers can do to address these complex communications because there are standards that guide the production of all wireless devices. These standards are technically called 802.11. Because of the industry to meet these standards, wireless networking is to use both simple and affordable today.
Wireless is easy to use
If all these stories of frequencies has you worried relax -. Hardware and software for wireless networking address all problems automatically, without user intervention. The wireless network, for all its ability, complicated, is much easier than you might expect to use.
