1. A method of detecting user presence, comprising:
- registering a client associated with said user on a host associated with said user and setting up a wireless communication pairing, wherein while setting up said pairing, said client measures said host wireless communication beacon power and uses it as a calibration threshold for distance detection; and
wherein said client measures a beacon power of said host and when said beacon power is above a power threshold, said client is determined to be proximate to said host;
wherein when said user moves away from said host and said beacon power received by said client is decreased and when said client receives a beacon packet without an association Aid (Pre-agreed Aid) in a traffic indication map (TIM) field and said beacon power is lower than said power threshold, said Client sends a sleep packet to said host to turn off a display associated with said host.

Abstract
An embodiment of the present invention provides a method of detecting user presence, comprising registering a client associated with the user on a host associated with the user and setting up a wireless communication pairing, wherein while setting up the pairing, the client measures the host wireless communication power and uses it as calibration threshold for distance detection, and wherein the client measures a beacon power of the host radio and when the beacon power is above a threshold, the client is determined to be proximate to the host.

10. An apparatus, comprising:
- a mobile device adapted for wireless communications with a host and setting up a wireless communication pairing between said host and said mobile client, wherein while setting up said pairing, said mobile device measures said host wireless communication beacon power and uses it as a calibration threshold for distance detection; and
wherein said mobile device measures a beacon power of said host radio and when said beacon power is above a power threshold, said mobile device is determined to be proximate to said host; wherein when said user moves away from said host and said beacon power received by said client is decreased and when said client receives a beacon packet without an association Aid (Pre-agreed Aid) in a traffic indication map (TIM) field and said beacon power is lower than said power threshold, said Client sends a sleep packet to said host to turn off a display associated with said host. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An apparatus, comprising:
- a host adapted for wireless communication with a mobile device and capable of setting up a wireless communication pairing between said host and said mobile device, wherein while setting up said pairing, said mobile device measures said host wireless communication beacon power and uses it as a calibration threshold for distance detection, wherein the calibration threshold is a minimum beacon power at which said client is determined to be proximate to said host; and
wherein said mobile device measures a beacon power of said host radio and when said beacon power is above a power threshold, said mobile device is determined to be proximate to said host; wherein when said user moves away from said host and said beacon power received by said client is decreased and when said client receives a beacon packet without an association Aid (Pre-agreed Aid) in a traffic indication map (TIM) field and said beacon power is lower than said power threshold, said Client sends a sleep packet to said host to turn off a display associated with said host. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)

28. A non-transitory machine-accessible medium that provides instructions, which when accessed, cause a machine to perform operations comprising:
-
detecting user presence by registering a client associated with said user on a host associated with said user and setting up a wireless communication pairing, wherein while setting up said pairing, said client measures said host wireless communication beacon power and uses it as a calibration threshold for distance detection, wherein the calibration threshold is a minimum beacon power at which said client is determined to be proximate to said host; and
wherein said client measures a beacon power of said host radio and when said beacon power is above a power threshold, said client is determined to be proximate to said host;wherein when said user moves away from said host and said beacon power received by said client is decreased and when said client receives a beacon packet without an association Aid (Pre-agreed Aid) in a traffic indication map (TIM) field and said beacon power is lower than said power threshold, said Client sends a sleep packet to said host to turn off a display associated with said host. - View Dependent Claims (29, 30, 31, 32, 33, 34)
