1. A method of reducing power consumption in a wireless network device, comprising:
- determining a duration prior to a beacon being periodically broadcast in the wireless network and received by the device;
comparing the duration against a predetermined value;
adjusting a duration of a sleep period in response to the comparing;
operating the wireless network device in a low frequency mode for the adjusted duration of the sleep period; and
in response to the adjusted duration of the sleep period expiring, operating the wireless network device in a high frequency mode and receiving the beacon while operating in the high frequency mode.

12. A wireless network apparatus, comprising:
-
a receiver for receiving a beacon periodically broadcast in a wireless network; and a processor configured and arranged to determine a duration prior to the start of the beacon being received, to compare the duration against a predetermined duration, to adjust a duration of a sleep period of the wireless network apparatus to operate the wireless network apparatus in a low frequency mode for the adjusted duration of the sleep period and, in response to the adjusted duration of the sleep period expiring, to operate the wireless network apparatus in a high frequency mode and receive the beacon while operating in the high frequency mode. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
