Abstract: 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.

Abstract: A method of powerline communications including a first node and at least a second node on a PLC channel in a PLC network. The first node sends a physical layer (PHY) data frame on the PLC channel including a preamble, PHY header, a MAC header and a MAC payload. The PHY header includes a destination address field having a destination address therein. The second node receives the data frame. The second node compares its network address to the destination address before decoding the MAC header and MAC payload, providing power savings by allowing the second node to not decode the MAC header or MAC payload if its network address does not match the destination address in the PHY header of the data frame.

Abstract: A method of powerline communications in a powerline communications (PLC) network including a first node and at least a second node. The first node transmits a data frame to the second node over a PLC channel. The second node has a data buffer for storing received information. The second node runs a flow control algorithm which determines a current congestion condition or a projected congestion condition of the data buffer based on at least one congestion parameter. The current congestion condition and projected congestion condition include nearly congested and fully congested. When the current or projected congestion condition is either nearly congested or fully congested, the second node transmits a BUSY including frame over the PLC channel to at least the first node. The first node defers transmitting of any frames to the second node for a congestion clearing wait time.
