Reverse-beacon indoor positioning system using existing detection fields
First Claim
1. A method for locating a reverse-beacon in a detection field comprising:
- providing a reverse-beacon comprising a transceiver and a computer in communication with said transceiver;
providing a plurality of system nodes deployed to form a detection field;
moving said reverse-beacon into said detection field;
receiving at said reverse-beacon, first system node signals from a first system node in said plurality of system nodes at said transceiver;
receiving at said reverse-beacon, second system node signals from a second system node in said plurality of system nodes at said transceiver;
receiving at said reverse-beacon, third system node signals from a third system node in said plurality of system nodes at said transceiver;
converting at said computer said first system node signals, said second system node signals, and said third system node signals to a historical dataset comprising;
a first system node identifier and a first system node distance associated with said first system node; and
a second system node identifier and a second system node distance associated with said second system node;
a third system node identifier and a third system node distance associated with said third system node;
repeating said receiving first system node signals, said receiving second system node signals, said receiving third system node signals, and said converting a plurality of times to form a plurality of said historical datasets;
determining at said computer a location of said reverse-beacon relative to said detection field, based upon comparing each of said historical datasets in said plurality of historical datasets to calculate a location of said reverse-beacon within said detection field.

Abstract
Indoor positioning systems and methods including a reverse-beacon for location determination and presence sensing technology. The reverse-beacon is any device comprising a transceiver and a computer operating with system nodes and will generally be in the form of a smartphone or other mobile computer. The systems and methods utilize wireless signals of any device that adheres to a general-purpose communication protocol, such as Bluetooth™ and Wi-Fi, to provide location-based services such as location determination and acting as a ground-truth field for presence sensing systems. The systems and methods operate by passively licensing to wireless communications that take place during the ordinarily course of operation of a wireless network irrespective of the presence of the reverse-beacon.
