1. An indoor location awareness method comprising:
- performing access point (AP) communications in an infrastructure each time a new access point is added, an access point is deleted, or the access point is updated within the infrastructure, wherein each AP includes self describing information about its coverage and information about neighboring APs within each AP'"'"'s range;
enabling a client device to receive coverage descriptors from all observable APs within an RF (radio frequency) scanning range of the client device; and
enabling the client device to use the coverage descriptors to reconstruct an image of the AP coverage as the client device traverses the infrastructure.

Abstract
An indoor location awareness method for locating a device using device-observable signals of known proximity sensors and device-unobservable signals of known proximity sensors. The exclusion of the possibility that the device is within an unobservable proximity sensor'"'"'s range increases the knowledge of the device'"'"'s true location. In addition to defining the location of the device, the device can predict the arrival and departure of unobservable proximity sensors as it moves throughout the environment.

16. An article comprising:
- a storage medium having a plurality of machine accessible instructions, wherein when the instructions are executed by a processor, the instructions provide for performing access point (AP) communications in an infrastructure each time a new access point is added, an access point is deleted, or the access point is updated within the infrastructure, wherein each AP includes self describing information about its coverage and information about neighboring APs within each AP'"'"'s range;
enabling a client device to receive coverage descriptors from all observable APs within an RF (radio frequency) scanning range of the client device; and
enabling the client device to use the coverage descriptors to reconstruct an image of the AP coverage as the client device traverses the infrastructure. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
