# 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
It isn’t different. WiFi is radio frequency. Your router is a radio transmitter – receiver, your phone is a radio transmitter receiver. Instead of talking, “Hey, y’all, this is Pea Packer on the Interstate, come back now, over”, or pounding out morse code, “dit dit dah dit” your transceivers are sending streams of zeros and ones, which the computers inside the transceivers turn into Tik Toks and advertisements for sneakers.
