  • Remote control system having a communication frequency lower than wireless fidelity signals
    Patent number: 8922353
    Abstract: A remote control system includes a control interface, a WiFi router, a bridge, and a low frequency control module. The WiFi router is linked to the control interface for communicating with the control interface via WiFi signals. The bridge is linked to the WiFi router for down-converting WiFi signals outputted from the WiFi router to low frequency signals and up-converting received low frequency signals to WiFi signals. The low frequency control module is linked to the bridge for communicating with the bridge via the low frequency signals.
