TECHNIQUES FOR EFFICIENT RF HEAT MAP REPRESENTATION

摘要

Techniques are described for aligning heat map information more efficiently to an actual geometry of an area of interest. A sequence is generated corresponding to consecutive runs of included and/or excluded grid points. The sequence is provided to a device in addition to heat map information corresponding to a number of grid points. The provided heat map information may be compressed and/or may be assigned to grid points in a reoriented area overlaying the area of interest. The device uses the sequence to map the heat map information to grid points in an area. In one technique, information corresponding to inaccessible locations are excluded from the heat map.

主权项

1. A method for providing access point (AP) vicinity information, comprising:
defining a rectangular array of grid points; determining a plurality of grid points based on the rectangular array of grid points, wherein the plurality of grid points overlay an area of interest and form a predefined shape; dividing the plurality of grid points into a plurality of included points and a plurality of excluded points, wherein the plurality of included points are proximate to the area of interest; determining a set of AP vicinity information for the plurality of grid points; compressing the set of AP vicinity information based on the rectangular array of grid points; and providing the compressed set of AP vicinity information and a sequence to a mobile device, wherein the sequence distinguishes the plurality of included points from the plurality of excluded points.
