Communication across a WiFi network is a lot like two-way radio communication.

  • A computer’s wireless adapter translates data into a radio signal and transmits it using an antenna.
  • A wireless router receives the signal and decodes it. The router sends the information to the Internet using a physical, wired Ethernet connection.

The process works also in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer’s wireless adapter.

The Process explained briefly:

WiFi network makes use of radio waves to transmit information across a network. The computer should include a wireless adapter that will translate data sent (Which will be 1’s and 0’s)converted into a radio signal by some analog to digital converters.

This converted Radio signal will be transmitted, through an antenna, to a decoder known as the router. Once decoded, the data will be sent to the Internet through a wired Ethernet connection.

As the wireless network works as a two-way traffic, the data received from the internet will also pass through the router to be coded into a radio signal that will be received by the computer’s wireless adapter.

If having several computers networked in your home, just create a wireless network with a wireless access point.
