Patent ID: 7245946

Claim:
A system for saving power in a wireless network, comprising: an access point having a priority queue; two or more stations with at least one station being a fixed wireless station; an Automatic Power Saving Delivery (APSD) frame having schedule information of a data transmission to the two or more stations; an algorithm in the access point for calculating a receiving power consumption of the data transmission for the two or more stations using a time of transmissions; determining a priority transmission ordering based on an increasing order of the receiving power consumption of the data transmission; and transmitting to the two or more stations the APSD frame of the schedule information using the priority transmission ordering so that the total power consumption of the network is minimized by transmitting in increasing order of the receiving power consumption of the data transmission, and wherein at least one of the two or more stations selectively awake from a sleep mode for the data transmission therewith based on the schedule.
