Traditional Methods vs Geolocation Weighted “Land Use & Building Use” Map Poor accuracy since based on assumptions.
OMC Cell Statistic and Propagated Best Server Coverage Accuracy highly dependent on cell size.
2D Geolocation using billions of MRs from Real Subscribers.
3D Geolocation using billions of MRs from Real Subscribers.
Accuracy dependent on algorithm used. Hybrid algorithm usually used.
Best in class for accuracy which separates inbuilding floor by floor, and outdoors.
