Wireless control refers to the communication of signals between different devices using radio waves. An example of this technology is Wi-Fi, which connects devices such as computers, tablets, smartphones, and other gadgets to the internet and to each other.

The functioning of Wi-Fi relies on a wireless router, which sends signals to nearby devices. These signals contain data that allow users to control devices remotely. For instance, applications available on smartphones can manage home functions like lighting or heating without needing wired connections, enhancing convenience and flexibility.
