# We use Wi-Fi every day to connect our devices to the internet, but how does it actually work? How do our devices communicate with the router and what makes Wi-Fi different from other types of wireless communication?
In: Technology
wifi isnt different from other wireless communication.
All wireless communications have a protocol and a frequency range. For example, Morse Code is a protocol for wireless human communication that uses the visible light frequency range.
wifi is just a specific set of protocol and frequencies designed for short range internet traffic.
bluetooth is a set of protocols and frequencies designed for very short range HID device (keyboard, speaker, etc) communication
4G is a set of protocols and frequencies designed for long range high speed internet trafic
5G is a set of protocols and frequencies designed for VERY HIGH SPEED line of sight internet
And a TV remote is a set of protocols and frequencies designed for short range line of sight TV control
etc.
These arent fundamentally different from each other or from morse code. At the end of the day, they are all just blinky “lights” turning on and off.
