2. Wifi communications
Wifi (Wireless Fidelity) is a standardized wireless communication system designed to link a range of IT devices (computers, tablets, etc.) in a common network. The range is limited to around 300 m, and the autonomy of a device equipped with it is of the order of a few hours. In comparison, Bluetooth has a shorter range and a lower data rate than WiFi, but the electronic consumption of the device equipped with it is lower.
