The present invention relates to the reduction of power consumption of wireless access points. In accordance with an embodiment of the invention, a wireless access point (10) comprises:
- a first radio transceiver (120) for operating a first radio communication channel (40) at a first power level, which first radio communication channel conveying user traffic (user_traffic) from or towards a wireless device (20),
- a second radio transceiver (140) operating a second radio communication channel (50) at a second lower power level, which second radio communication channel conveying control traffic (ctrl_traffic) from the wireless device,
- a controller (130) for monitoring the receipt of wake-up messages (wake_up) from the wireless device through the second radio communication channel, and for switching off the first radio transceiver in the event of no wake up message being received within a pre-determined time interval. The present invention also relates to a method for saving power consumption of a wireless access point. |
