Mobile Device Tag Data Aggregation via Signal Fingerprint Matching

The patent creates a virtual copy of the physical environment by generating signal fingerprints that represent radio signal characteristics at specific locations. Instead of directly triangulating signals in challenging environments, the system creates fingerprint copies of signal profiles at known locations and matches them against observed signals, enabling location determination where traditional triangulation fails.

The patent introduces signal fingerprints as an intermediary between the radio signal environment and location determination. Rather than directly using signal strength for triangulation, the system uses fingerprints as a mediator that captures environmental characteristics and enables location matching through comparison, bridging the gap between signal observations and location identification in complex environments.

The patent replaces complex triangulation calculations with a simpler fingerprint matching approach. Instead of performing complex mathematical triangulation to derive precise location coordinates, the system creates fingerprint copies of signal environments and matches them to identify locations, significantly reducing computational complexity while maintaining effectiveness in challenging environments.

The patent inverts the traditional approach by not trying to calculate location from signals, but rather by matching signals against pre-collected fingerprint profiles. Instead of deriving location through complex forward calculation, the system works backward by comparing observed signals against a database of known signal profiles, simplifying the determination process.

The patent converts the harmful effects of signal fade and multipath into beneficial information by capturing these characteristics in signal fingerprints. Instead of treating signal degradation as noise to be eliminated, the system uses the unique signal profile including fade and multipath effects as identifying characteristics for location matching, turning environmental challenges into location identifiers.

The patent creates fingerprints that copy the complete signal environment including harmful effects. By capturing signal profiles that include fade and multipath characteristics at known locations, the system preserves these previously harmful effects as useful identification data for matching and location determination.
