A wireless or wifi or wireless network uses radio waves, just like mobile phones and other similar communication devices. In fact, communication through one of these networks is very similar to a bidirectional radio communication.
Wireless Network – How Does a Wi-Fi Wireless Network Work? – Best Tips
What happens more or less, is that a wireless adapter of the computer translates the data into radio signals and transmits them using an antenna. On the other hand, a wireless router receives the signal and decodes it and sends the information to the Internet using a physical cable connection.
How Does a Wi-Fi Wireless Network Work?
The process in the wireless network also works in the reverse direction, where the router receives the information from the Internet, transforming it into a radio signal and sending it to the computer adapter.
The type of radio used in Wi-Fi communication in wireless network is similar to that used in walkie-talkies, mobiles and other devices. They can transmit and receive radio waves, and can convert ones and zeros to these waves and vice versa. However, wireless radio has a noticeable difference from other radios.
They can transmit at frequencies of 2.4 GHz or 5 GHz in the wireless network. This frequency is considerably higher than the frequency used in mobile phones or some televisions. This frequency difference allows the signal to carry more data. The standards it uses are in the family of 802.11 protocols, which come in several formats:
The Wireless, 802.11a protocol transmits at 5 GHz and can move up to 54 megabits of data per second. It also uses OFDM, which is a more efficient coding technique that splits the radio signal into several different signals before it reaches the receiver. This greatly reduces interference.
What Is 802.11b protocol in wireless network/WiFi?
The 802.11b protocol is the slowest and cheapest standard of all. For some time, the cost it had made it quite popular, but now it is becoming less common as the price is reduced in faster protocols. The 802.11b protocol transmits at 2.4 GHz and handles up to 11 megabits of data per second, using CCK coding.
Wifi Wireless Network Protocol In 802.11g:
The 802.11g protocol also transmits to 2.4 GHz, but is much faster. It can handle up to 54 megabits of data per second, and is faster because it uses the same OFDM coding as the 802.11a protozoon.
Wireless Network Protocol in 802.11n:
The 802.11n protocol is the newest protocol currently available. This standard significantly improves speed and use. To give an example, although 802.11g theoretically moves up to 54 mbps, it actually only moves up to 24 mbps due to network congestion. However, 802.11n can reach speeds up to 140 mbps.
Wifi in wireless network can stream in any of these three bands. They can also jump quickly between different bands. Frequency jumps help reduce interference and allow multiple devices to use the same wireless connection simultaneously.
Devices used to connect to the Internet over Wi-Fi, have some kind of wireless adapter to do so, and therefore can use a single router to connect to the Internet. This connection is virtually invisible and is usually quite reliable. However, users may experience interference or loss of connection.
