LOW POWER CONTROL FOR WIRELESS LAN COMMUNICATION

摘要

A wireless networking device includes a transceiver that transmits and receives communications over a wireless local area network (WLAN), and a processor cooperatively operable with the transceiver. The processor transmits over the transceiver one WLAN frame of a file transfer to a receiving networking device and then transitioning from transmit power level down to a state of receive power level while waiting for an“ACK”signal to the transmitting. The processor also receives over the transceiver the“ACK”signal from the receiving networking device, and the“ACK”signal triggers going into a doze state of a low power level for a predetermined period of time. The predetermined period of time expires and triggers transitioning the processor to a state of receive power level for an inter-frame space while waiting to transmit a next WLAN frame. The low power receive power level is lower than the receive power level.
