1. A method for transmitting beacon frames for a wireless data link from an access point, comprising:
- determining that an electronic device associated with the access point supports a power save mode;
based on a highest common factor of a listen interval for the electronic device and a delivery traffic indication message interval for the access point, determining a beacon frame interval; and
transmitting the beacon frames at the beacon frame interval.

Abstract
A method and apparatus are described for transmitting beacon frames to an electronic device over a wireless data. In the described embodiments, a processing subsystem is coupled to a transceiver and is configured to determine a beacon frame interval based on a highest common factor of a listen interval for the electronic device and a delivery traffic indication message interval, and to control the transceiver to transmit a beacon frame each beacon frame interval.
