TRACKING OF AND COMMUNICATION WITH MOBILE TERMINALS USING BATTERY-POWERED WIRELESS NETWORK INFRASTRUCTURE Russian patent published in 2013 - IPC H04W4/00 

FIELD: radio engineering, communication.

SUBSTANCE: method comprises steps of: (a) turning a transmitter and a receiver of a network infrastructure node to a power-off state; b) powering-on the transmitter of the network infrastructure node for a limited transmission time frame; c) during the transmission time frame, transmitting a beacon message comprising an identifier of the network infrastructure node, channel characteristics of the network infrastructure node and a powering-on schedule of the receiver of the network infrastructure node, for allowing mobile terminal nodes in the network to communicate with the network infrastructure node; d) powering-on the receiver of the network infrastructure node during a limited reception time frame in accordance with the schedule, for enabling the receiver to receive messages transmitted by the mobile terminal nodes in the network.

EFFECT: low power consumption of network infrastructure nodes in a wireless network.
