Abstract

A wireless network that may include one or more access points, one or more wireless controllers and one or more appliances. The one or more access points include, or may be coupled with, a server location agent that operates to determine or estimate the locations of the one or more wireless controllers. Upon determining the location of the one or more wireless controllers, the server location agent may determine a proximity of one or more appliances to the wireless controllers and may cause the wireless controllers to display a customized user interface that may be configured based on proximity to one or more appliances as well as policies and/or historical data. In addition, the appliances in the user'"'"'s proximity may be automatically switched on and controlled to serve the user.

Claims

1. An article comprising one or more computer-readable medium having stored thereon content that, when executed, cause one or more processors to:

estimate a location of a wireless controller based, at least in part, on a detected signal strength of the wireless controller in relation to retrieved previously generated location-signal strength information, wherein the wireless controller comprises a wireless control device for at least one of the one or more network appliances;

select one or more of the network appliances based, at least in part, on the estimated location, device policies associated with the wireless controller, and historical data corresponding to previous use of the wireless controller,

wherein the selected one or more network appliances share a wireless local area network, and the appliances comprise one or more of;

one or more televisions, one or more radio receivers, one or more compact disc (CD) players, one or more video cassette recorders (VCRs), one or more digital video disc (DVD) players, one or more satellite decoders, one or more cable television decoders, one or more set top boxes, one or more computer systems, and one or more electronic mail appliances; and

present a customized user interface with the wireless controller corresponding to the selected one or more network appliances to control one or more appliances wherein the customized user interface is based, at least in part, on the estimated location of the wireless controller, the proximity of the wireless controller to one or more appliances, previous selections made with the wireless controller, and environmental conditions including time of day, day of the week and month.

2. The article of claim 1 wherein the content that causes the one or more processors to use the retrieved location-signal strength information to estimate the current location for the wireless controller comprises content that, when executed, causes the one or more processors to:

select location-signal strength information having a signal strength closest to the determined signal strength; and

estimate the current location of the wireless controller to be a location from the selected location-signal strength information.

3. The article of claim 2 wherein the content that causes the one or more processors to select location-signal strength information having a signal strength closest to the determined signal strength comprises content that, when executed, causes the one or more processors to:

select location-signal strength information associated with one or more of the network appliances sharing the wireless local area network.

4. The article of claim 1 wherein the content that causes the one or more processors to estimate the location of the wireless controller comprises content that, when executed, causes the one or more processors to predict the location of the wireless controller.

5. The article of claim 4 wherein the content that causes the one or more processors to predict the current location for the wireless controller comprises content that, when executed, causes the one or more processors to:

retrieve location-signal strength information corresponding to multiple signal strengths; and

interpolate the current location of the wireless controller using at least two of the retrieved location-signal strength information.

6. The article of claim 4 wherein the content that causes the one or more processors to predict the current location for the wireless controller comprises content that, when executed, causes the one or more processors to:

retrieve location-signal strength information corresponding to multiple signal strengths; and

extrapolate the current location of the wireless controller using at least two of the retrieved location-signal strength information.

7. A method comprising:

estimating a location of a wireless controller based, at least in part, on a detected signal strength of the wireless controller in relation to retrieved previously generated location-signal strength information, wherein the wireless controller comprises a wireless control device for at least one of the one or more network appliances;

selecting one or more of the network appliances based, at least in part, on the estimated location, device policies associated with the wireless controller, and historical data corresponding to previous use of the wireless controller,

wherein the selected one or more network appliances share a wireless local area network, and the appliances comprise one or more of;

one or more televisions, one or more radio receivers, one or more compact disc (CD) players, one or more video cassette recorders (VCRs), one or more digital video disc (DVD) players, one or more satellite decoders, one or more cable television decoders, one or more set top boxes, one or more computer systems, and one or more electronic mail appliances; and

presenting a customized user interface with the wireless controller corresponding to the selected one or more network appliances to control one or more appliances wherein the customized user interface is based, at least in part, on the estimated location of the wireless controller, the proximity of the wireless controller to one or more appliances, previous selections made with the wireless controller, and environmental conditions including time of day, day of the week and month.

8. The method of claim 7 wherein using the retrieved location-signal strength information to estimate the current location for the wireless controller comprises:

selecting location-signal strength information having a signal strength closest to the determined signal strength; and

estimating the current location of the wireless controller to be a location from the selected location-signal strength information.

9. The method of claim 8 wherein selecting location-signal strength information having a signal strength closest to the determined signal strength comprises:

selecting location-signal strength information associated with one or more of the network appliances sharing the wireless local area network.

10. The method of claim 7 wherein estimating the location of the wireless controller comprises predicting the location of the wireless controller.

11. The method of claim 10 wherein predicting the current location for the wireless controller comprises:

retrieving location-signal strength information corresponding to multiple signal strengths; and

interpolating the current location of the wireless controller using at least two of the retrieved location-signal strength information.

12. The method of claim 10 wherein predicting the current location for the wireless controller comprises:

retrieving location-signal strength information corresponding to multiple signal strengths; and

extrapolating the current location of the wireless controller using at least two of the retrieved location-signal strength information.
