1. A method comprising, at a mobile device:
- determining a first variation between one or more electrical signals representing a baseline probability distribution and one or more electrical signals representing a first probability distribution for signals received from a first set of transmitters assigned to a first region of a structure;
determining a second variation between the one or more electrical signals representing the baseline probability distribution and one or more electrical signals representing a second probability distribution for signals received from a second set of transmitters assigned to a second region of the structure;
determining whether the mobile device is located in the first region or the second region based, at least in part, on a comparison of the first variation and the second variation; and
generating one or more electrical signals indicating a determined location of the mobile device with respect to the structure.

Abstract
Methods and apparatuses are provided that may be implemented in a mobile device to determine two or more variations between a baseline probability distribution and two or more probability distributions for signals received from two or more sets of transmitters assigned to two or more regions of a structure. The methods and apparatuses may be further implemented to determine whether the mobile device is located in at least one of the two or more regions based, at least in part, on a comparison of the two or more determined variations.

11. An apparatus for use in a mobile device, the apparatus comprising:
-
means for determining; a first variation between a baseline probability distribution and a first probability distribution for signals received from a first set of transmitters assigned to a first region of a structure; and a second variation between the baseline probability distribution and a second probability distribution for signals received from a second set of transmitters assigned to a second region of the structure; and means for determining whether the mobile device is located in the first region or the second region based, at least in part, on the first variation and the second variation. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A mobile device comprising:
-
a network interface; and a processing unit to; determine a first variation between a baseline probability distribution and a first probability distribution for signals received via the network interface from a first set of transmitters assigned to a first region of a structure; determine a second variation between the baseline probability distribution and a second probability distribution for signals received via the network interface from a second set of transmitters assigned to a second region of the structure; and determine whether the mobile device is located in the first region or the second region based, at least in part, on a comparison of the first variation and the second variation. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
