Method for evaluating positioning parameters and system

A non-transitory computer readable medium that contains instructions that when executed in a computer having a memory and one or more processors causes the one or more processors to:

• assign an initial vector of positioning parameters to each anchor;
• capture and store a plurality of RSSI measurements within the defined area by receiving signals from the at least three stationary access beam points;
• cluster the plurality of RSSI measurements in a plurality of subsets, particularly wherein the number of subsets corresponds to the number of the at least two grids;
• associate each subset of the plurality of subsets to a respective one of the at least two grids;
• and
• update the initial vector assigned to the anchor of the respective one of the at least two grids based on the vector of initial positioning parameters and the subset of the plurality of subsets associated with the respective one of the at least two grids.

System for evaluating positioning parameters in a defined space, particularly in an indoor space, wherein the defined space is affected by at least three stationary access beam points and over which a grid pattern is laid with at least two grids, each grid having an anchor, and wherein the system comprises

• a memory;
• one or more processors, the one or more processors adapted to execute one or more instructions that:
• assign an initial vector of positioning parameters to each anchor;
• capture and storing a plurality of RSSI measurements within the defined area by receiving signal from the at least three stationary access beam point;
• cluster the plurality of RSSI measurement in a plurality of subsets, wherein the number of subsets corresponds to the number of the at least two grids;
• assign each subset of the plurality of subsets to a respective one of the at least two grids;
• and
• update the initial vector assigned to the anchor of the respective one of the at least two grids based on the vector of initial positioning parameters and the subset of the plurality of subsets associated with the respective one of the at least two grids.
