RF pattern-matching location engine for indoor and urban
This technology improves the ability to pinpoint where a mobile device is located by combining two types of evidence: how the device's radio signal compares to a pre-built map of expected signal patterns at known locations, and how the device's signal relates to other nearby mobile devices whose locations are also unknown. By fusing these two sources of information—infrastructure-based signal fingerprinting and peer-to-peer signal measurements—the system produces a more accurate location estimate than either method alone. This is especially useful in environments like indoor spaces or dense urban areas where GPS is unreliable and traditional cell-tower triangulation is imprecise.
What you could build
A location engine or SDK licensed to mobile network operators, public safety software vendors, or enterprise Wi-Fi/private LTE providers to enable accurate indoor and urban positioning without GPS. Primary buyers would be first-responder dispatch platforms, warehouse management system vendors, or smart building operators.
Who in Virginia should care
Northern Virginia's concentration of federal agencies, defense contractors (Booz Allen, Leidos, SAIC), and public safety technology firms creates natural buyers for indoor/denied-environment positioning systems.
Readiness: Lab validated
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
