Components of Wi-Fi Working Process

• Radio Signals

Radio waves are the primary elements that make a Wi-Fi network smooth and effective. Wi-Fi uses radio frequencies to communicate with different devices through diverse frequency bands— 2.4 GHz and 5 GHz. 

Every Wi-Fi frequency band has multiple channels imbibed in it so the devices can send and receive data. The purpose of the Wi-Fi channels is to reduce interference and overlap between the different devices as it can lead to a reduction in speed and cause the internet to slow down. The less traffic, the less congestion. 

• Antenna

The digital device needs to have a wireless adapter that will translate data sent into a radio signal. This same signal will be further transferred through the antenna (external or internal) to a decoder which is our router. 

• Router

Once the signal is decoded, the data is forwarded to the Internet through a wired Ethernet connection. As the wireless network works in a two-way defined procedure, the data received from the internet will also transfer from the router to be further encoded into a radio signal that will be received by the computer’s wireless adapter. The information is then decoded and finally broadcasted onto the digital screens.
