Solution Approach 2:

The system utilizes mobile devices already present in the network to self-provide location and timing information for antenna determination. By leveraging existing infrastructure and devices rather than requiring dedicated measurement equipment, the system achieves accurate antenna location determination while maintaining operational simplicity.

Inventive Principle:
Principle #25Self-service

Solution Approach 1:

The patent employs mobile devices that serve multiple functions: they act as both communication endpoints and location measurement instruments. By making the measurement system universal and leveraging existing multi-functional devices rather than dedicated specialized equipment, the system achieves high measurement precision while minimizing the addition of complex dedicated infrastructure.

Solution Approach 2:

The patent segments the mobile device population into different groups based on their suitability for measurement, processing data from selected devices rather than treating all devices uniformly. This segmentation allows the system to focus computational resources on the most valuable measurement sources, improving efficiency while maintaining accuracy.
