Wi-Fi Module
A small radio board in a smart appliance that connects to your home network for remote control and monitoring.
Definition
The Wi-Fi module is the small radio board inside a smart appliance that handles connection to your home wireless network. Most appliance Wi-Fi modules support only 2.4 GHz networks (not 5 GHz), so dual-band routers may need to broadcast a 2.4 GHz SSID separately for setup. The Wi-Fi module is typically a separate, replaceable board from the main appliance controller, so a Wi-Fi failure does not break the appliance's normal operation — and a failed Wi-Fi module can be swapped without affecting the rest of the unit.
