How Does Wireless Networking Work?

Have you ever asked yourself how does wireless networking work? The main principle that is involved in wireless networking is the usage of radio waves to our convenience. In fact, radio waves constitute the main medium through which information is transferred and received.

The transmission of data in computers happens through binary ones and zeros i.e. in simpler words in the digital format. The same communication mechanism is application to the movement of radio waves too. We are often not aware that these radio waves are all around us and we can hardly feel them or hear those transmitting data to that mobile phone or a wireless laptop that is beside you.

It is through a mechanism that is similar to Morse code which transmits information in the form of dots and dashes over a radio. The radio links come with a transmitter and a receiver. While the transmitter transmits the radio signals, the receiver in the range of the transmitter will grasp the signal and output what it has to. This is similar to something like infrared but for one small difference that infrared requires a line of sight to be maintained between the transmitter and the receiver and also the data transfer is in the form of IR radiation.

Also, a wireless network makes use of something called as frequency hopping technique which helps in transmitting different frequencies by simply switching between them. Also, each device has signals received in its own allotted spectrum. This is the reason why wireless networks are immune to the interfering radio signals from any other wireless device. The information in case of wireless networking is sent in very high frequencies, almost in the range of 2.4 GHz. This brief concept answers the question 'How does wireless networking work?'
