Wireless control refers to the communication of signals between different devices via radio waves. A prime example of this technology is Wi-Fi, which connects various devices like computers, tablets, and smartphones to the internet or to each other without the need for physical wires.

The Wi-Fi signal is transmitted from a wireless router to compatible devices, translating those signals into data that can be utilized to control various functions, such as managing home heating or lighting systems remotely. Additionally, many smartphone applications facilitate the control of these systems wirelessly, offering convenience and flexibility in device management.
