Abstract

Embodiments of an apparatus and methods, for monitoring an environment using a wireless network and sending a signal if movement is detected, are generally described herein. Other embodiments may be described and claimed.

Claims

1. A method comprising:

determining baseline conditions corresponding to a wireless communications link within a physical region;

monitoring subsequent conditions corresponding to the wireless communications link;

determining a difference profile for a comparison between the baseline conditions and the subsequent conditions; and

transmitting a command signal if the difference profile corresponds to a security breach condition in the physical region.

2. The method of claim 1, wherein the wireless communications link is a wireless local area network.

3. The method of claim 1, wherein the conditions are radio frequency energy signals received at an energy level.

4. The method of claim 3, further including specifying the energy level of the conditions when transmitting a request for baseline conditions over the wireless communications link.

5. The method of claim 1, wherein the conditions are received signal strength indicator signals.

6. The method of claim 1, further including periodically measuring a background noise signal.

7. The method of claim 6, further including forming ratios of the conditions by the background noise signal.

8. The method of claim 1, wherein the conditions are packet error rate data.

9. The method of claim 1, wherein transmitting the command signal over the wireless communication link.

10. The method of claim 1, wherein transmitting the command signal through an interface to a modem or an autodialer.

11. The method of claim 1, wherein the command signal is sent in response to a movement by an intruder in the physical region.

12. A wireless communications apparatus comprising:

transmitting circuitry to transmit a request for baseline conditions over a wireless communications link;

receiving circuitry to receive baseline conditions and subsequent conditions over the wireless communications link;

a controller to convert the baseline conditions to baseline data and the subsequent conditions to subsequent data;

a memory to store the baseline data and a security breach condition; and

the controller to determine a difference profile between the baseline data and the subsequent conditions and to generate a command signal if the difference profile corresponds to a security breach condition.

13. The wireless communications apparatus of claim 12, wherein the transmitting circuitry and the receiving circuitry comprise an antenna, a power amplifier, a low noise amplifier, and a filtering device.

14. The wireless communications apparatus of claim 12, wherein the controller comprises a cache memory, a baseband subsystem, a media access control processor, an analog to digital controller and a digital to analog controller.

15. The wireless communications apparatus of claim 12, wherein the memory is a separate volatile or non-volatile memory device.

16. The wireless communications apparatus of claim 12, further including an interface to send a command signal through a modem or an autodialer.

17. The wireless communications apparatus of claim 12, wherein the transmitting and receiving circuitry is used to send a command signal.

18. A machine-accessible medium that provides instructions, which when accessed, cause a machine to perform operations comprising:

determining baseline conditions corresponding to a wireless communications link within a physical region;

monitoring subsequent conditions corresponding to the wireless communications link;

determining a difference profile for a comparison between the baseline conditions and the subsequent conditions; and

transmitting a command signal if the difference profile corresponds to a securing breach condition in the physical region.

19. The machine-accessible medium of claim 18, wherein the wireless communications link is a wireless local area network.

20. The machine-accessible medium of claim 18, further including specifying the energy level of the conditions when transmitting a request for baseline conditions over the wireless communications link.
