Solution Approach 1:

The patent divides the positioning space into multiple grids, with each grid containing position information and communication signal intensity data. By segmenting the environment into discrete grid units, the system can accurately determine position by matching detected signal intensities with pre-stored grid data, effectively overcoming signal interference in indoor environments.

Inventive Principle:

Solution Approach 2:

The system performs preliminary actions by pre-collecting and storing communication signal intensities from multiple radio stations for each grid location before actual positioning is needed. This pre-established database of signal intensities allows for rapid and accurate position determination when the electronic device enters the area, without requiring real-time complex calculations that would be affected by signal interference.
