CLIENT' DEVICE POWER REDUCTION IN WIRELESS NETWORKS HAVING NETWORK-COMPUTED CLIENT' LOCATION |
摘要 |
A method of reducing client power consumption in a wireless network including a network server which provides computed client' locations, at least one access point (AP), and a plurality of wireless stations (STAs) including a first wireless station (STA1). The AP periodically sends beacon frames that span a beacon period, wherein at least a first beacon frame is sent during the beacon period. The STA1 sends a location request frame to the AP requesting a STA1 location. During the beacon period the STA1 wakes up from a powersave (PS) mode or a sleep mode and sends a PSPoll frame to the AP. Responsive to the PSPoll frame, the AP replies with a priority response being a data frame including a location response packet including the STA1 location or a Null frame if the STA1 location is not available.
