1. A communications system, comprising a wireless access device and a plurality of wireless fidelity (Wi-Fi) devices connected to the wireless access device, wherein the wireless access device comprises a cellular transceiver and a Wi-Fi transceiver;
the wireless access device is configured to:
receive a cellular signal by using the cellular transceiver,
convert the cellular signal into a Wi-Fi signal,
send the Wi-Fi signal by using the Wi-Fi transceiver, and
upon determining that both a first preset condition and a second preset condition are met, reduce uplink transmit power of a cellular network, to reduce interference from the cellular signal to the Wi-Fi signal; and
each of the plurality of Wi-Fi devices is configured to: receive the Wi-Fi signal and access a Wi-Fi network, wherein
the first preset condition comprises: there is a Wi-Fi device whose received signal strength parameter and signal quality parameter are less than a first threshold in the plurality of connected Wi-Fi devices, the uplink transmit power of the cellular network is greater than or equal to a second threshold, and a received signal strength parameter and a signal quality parameter of the cellular network is greater than or equal to a third threshold, wherein a signal status parameter comprises a received signal strength parameter and a signal quality parameter, and
the second preset condition comprises: a Wi-Fi rate of a Wi-Fi device with a smallest received signal strength parameter and a smallest signal quality parameter among the plurality of connected Wi-Fi devices is less than a fourth threshold, and an air interface throughput of the cellular network is greater than or equal to a fifth threshold.
