ABSTRACT:
The invention provides a method of mapping into tessellating triangles an area from a set of sample point spaced over the area. First, each point is connected to every other point to create a group of lines. Then the number of intersections of each line is counted. The line or lines with the greatest number of intersections is removed from the group. The counting and line removal steps are repeated until the group is confined to lines with no intersections, these lines defining triangles. The invention has particular application to the division into triangles of an area served by a wireless LAN, in order to display the variation of a radio signal parameter across the area.
