Abstract

Methods, systems, and apparatus are provided for power management. The methods include detecting a triggering event at a sensor device of a security system; activating a wireless transmitter/receiver from a low power mode; detecting a broadcast beacon frame from an access point device; transmitting a probe request frame that includes triggering event data; and returning the wireless transmitter/receiver to a low power mode.

Claims

1. A method comprising:

receiving, at an actuator device of a security system, a radio frequency (RF) wake-up signal from a security management device of the security system, wherein the RF wake-up signal is received at a radio frequency module of the actuator device;

activating a wireless transmitter/receiver from a low power mode in response to the received RF wake-up signal, wherein the wireless transmitter/receiver is distinct from the radio frequency module;

establishing communication with the security management device using the wireless transmitter/receiver;

receiving actuation instructions from the security management device; and

performing actuation of the actuation device.

2. The method of claim 1, wherein the actuator device is a door actuator and performing actuation includes opening an associated door.

3. The method of claim 1, wherein the radio frequency wake-up signal is an RF signal and wherein the wireless transmitter/receiver transmits and received data using one or more 802.11 wireless protocols.

4. The method of claim 1, further comprising returning the wireless transmitter/receiver to the low power mode after receiving the actuation instructions.

5. The method of claim 1, wherein establishing communication with the security management device includes using a modified form of 802.11 wireless protocols to initiate communication with the security management device.

6. A security system comprising:

an actuator device and a security management device, wherein the actuator device is configured to perform operations including;

receiving, at the actuator device of a the security system, a radio frequency (RF) wake-up signal from the security management device, wherein the RF wake-up signal is received at a radio frequency module of the actuator device;

activating a wireless transmitter/receiver from a low power mode in response to the received RF wake-up signal, wherein the wireless transmitter/receiver is distinct from the radio frequency module;

establishing communication with the security management device using the wireless transmitter/receiver;

receiving actuation instructions from the security management device; and

performing actuation of the actuation device.

7. The system of claim 6, wherein the actuator device is a door actuator and performing actuation includes opening a corresponding door.

8. The system of claim 6, wherein the radio frequency wake-up signal is received at a radio frequency module of the actuator device configured to transmit and receive radio frequency signals, wherein the radio frequency module is distinct from the wireless transmitter/receiver.

9. The system of claim 6, further comprising returning the wireless transmitter/receiver to the low power mode after receiving the actuation instructions.

10. The system of claim 6, wherein establishing communication with the security management device includes using a modified form of 802.11 wireless protocols to initiate communication with the security management device.
