Abstract
A method and system of creating microlocation zones by defining virtual boundaries using a system of one or more transmitters and receivers with one or more spatially-correlated antennas.
Claims22
A system for establishing location information with respect to a portable device and a data access point, the system comprising:
- a master device disposed in a fixed position relative to the data access point, the master device capable of communicating with at least one of the portable device and one or more sensor devices;
- a plurality of antennas, each of the plurality of antennas configured to receive wireless communications and provide an antenna output corresponding to the wireless communications;
- wherein a characteristic signal is determined for at least one antenna output based on a plurality of time-spaced measurements of the at least one antenna output;
- wherein an output signal is determined based on a function of the characteristic signal, wherein a location of the portable device is determined relative to the data access point based on the output signal, whereby the function mitigates environmental effects in the at least one antenna output;
- wherein at least one sensor device of the one or more sensor devices is operably coupled to the plurality of antennas, wherein the at least one sensor device is configured to determine the output signal, and wherein the at least one sensor device communicates a signal characteristic of the output signal to the master device;
- and
- wherein a zone is determined based on a receive range of the plurality of antennas located in or near the data access point,
- wherein the master device is configured to identify presence of the portable device within the zone based on the output signal and to authorize to perform at least one service function between the portable device and the data access point,
- wherein the at least one service function includes a physical access to connection points, adjustment of access to data, and targeted marketing for a user of the portable device.

A method of establishing location information with respect to a portable device and a data access point, the method comprising:
- disposing a master device in a fixed position relative to the data access point;
- communicating between the master device and at least one of the portable device and one or more sensor devices;
- receiving wireless communications in a first antenna;
- providing first output corresponding to the wireless communications received in the first antenna;
- receiving wireless communications in a second antenna;
- providing second output corresponding to the wireless communications received in the second antenna;
- determining a characteristic signal for at least one antenna output of the first and second outputs based on a plurality of time-spaced measurements of the at least one antenna output;
- determining an output signal based on a function of the characteristic signal;
- determining a location of the portable device relative to the data access point based on the output signal, whereby the function mitigates environmental effects in the at least one antenna output;
- determining a zone based on a receive range of the first and second antennas located in or near the data access point;
- identifying presence of the portable device within the zone based on the output signal;
- and
- authorizing performance of at least one service function between the portable device and the data access point, wherein the at least one service function includes a physical access to connection points, adjustment of access to data, and targeted marketing for a user of the portable device.
