System for relative positioning of access points in a real time locating system
First Claim
1. A method for relative positioning of access points in a real time locating system, the method comprising:
- receiving layout information of a work area, wherein the layout information comprises architectural attributes and infrastructure attributes of the work area;
determining a number of a plurality of access points to position in the work area based on the architectural attributes of the work area;
determining, by a processor, a positioning of the plurality of access points in the work area, wherein the positioning promotes a coverage and an accuracy of locating at least one test radio frequency tag in the work area;
receiving an indication of an actual physical location of the at least one test radio frequency tag in the work area;
determining an expected location of the at least one test radio frequency tag based on readings of the plurality of access points;
determining the accuracy of locating the at least one test radio frequency tag by comparing the actual physical location of the at least one test radio frequency tag to the expected location of the at least one test radio frequency tag, anddetermining a repositioning of at least one of the plurality of access points when at least the accuracy does not satisfy a threshold, and providing a graphical representation of the positioning of each of the plurality of access points in the work area, relative to one another, when at least the accuracy satisfies the threshold.

Abstract
A system is described for relative positioning of access points in a real time locating system. The system may include a memory, interface, and processor. The memory may store layout information for a work area which includes architectural and infrastructure attributes. The processor may determine a number of access points to position in the work area based on the architectural attributes. The processor may determine a placement of a test tag in the work area based on the infrastructure attributes. The processor may determine a positioning of the access points in the work area which substantially maximizes coverage and accuracy of locating the test tag in the work area. The processor may determine a repositioning of one of the access points when the coverage and accuracy do not satisfy a threshold. The processor may provide a graphical representation of the positioning of the access points, when the threshold is satisfied.
