How WiFi works

Comms, Information

Wifi is everywhere.  From Coffee shops to Office Buildings.  Your home and even now on an airplane.

Wireless networks (aka WiFi) is a wireless network of radio waves (just like you have for your mobile phone) that connects your computer/smart phone/devices to a wireless router which takes the signal received, decodes it and then sends that information onto the world wide web using a physical ethernet wired connection.

The system works both way so you can send and receive wireless information using WiFi.  Similar to how a walkie-talkie works, WiFi signal is transferred in radio waves and then converted into 1s and 0s.  WiFi signal is generally transmitted at a frequency of 2.4GHz of 5 GHz (you may even have a WiFi box at home that produces both signals though these are being phased out as they carry lower data speeds).  This signal frequency is a lot higher that what you find on a mobile phone and the higher the frequency, the larger amount of data needs to be carried.
