# 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
Everything with computers is broken down into 1’s and 0’s and WiFi is no exception to this.
When two WiFi devices communicate with each other, they send radio waves that have different properties where the receiver can interpret the signal as a 1 or a 0. By changing properties of the radio wave such as the frequency or phase, the receiver uses that difference to determine if the signal being sent is a 1 or 0, and then creates a complete message from that information.
