1. An indoor location identification system, comprising:
- a communications processor configured to receive a measurement package from a mobile device in an indoor area, wherein the indoor area is associated with a plurality of zones;
a location database for storing a first model associating a plurality of measurement packages with the plurality of zones; and
a location processor in communication with the communications processor and the location database, wherein the location processor is configured to;
calculate a first plurality of probabilities based on a first measurement package and the first model, wherein the first measurement package is received by the communications processor and wherein each probability in the first plurality of probabilities is associated with a zone of the plurality of zones, andidentify a zone corresponding to the first measurement package based on the first plurality of probabilities.

Abstract
Many indoor location services do not require precise knowledge of the position of a mobile device, but simply whether a mobile device is within a particular zone of an indoor area. Existing signals in an indoor space may provide enough information to distinguish between different zones of an indoor area, allowing a server to provide indoor location services without requiring the installation of new signal sources in the indoor area.
