Spatial Location Indoors Using Standard Fluorescent Fixtures
WARF: P160310US01

Inventors: Xinyu Zhang, Chi Zhang

The Invention
A system for identifying the location of the mobile device uses standard fluorescent light fixtures commonly found in indoor environments and detects minor variations in the light output of those fixtures caused by normal manufacturing variation. These variations are catalogued as identifying fingerprints together with location of the light fixtures to provide for navigation.
