View Patent ↗An apparatus, method, and system, the apparatus including a housing; a light source, disposed in the housing, including at least one source of illumination; a radio frequency (RF) transmitter located on or in the housing; and at least one directional radiating element at least partially enclosed by the housing and coupled to RF transmitter, the at least one directional radiating element directing a RF signal transmitted by the RF transmitter in a predetermined direction away from the housing.
1. A method comprising:
receiving, by a processor of a mobile device located in a vicinity of a lighting fixture, a signal transmitted from a radio frequency (RF) transmitter co-located with the lighting fixture and coupled to a directional radiating antenna that radiates a RF signal transmitted by the RF transmitter into a predetermined shape that is not omni-directional;
determining, by the processor of the mobile device, a strength of the received signal;
determining an identity of the RF transmitter based on an indication of a unique identifier of the RF transmitter included in the received signal; and
determining a location of the mobile device at the time the signal was received based, at least in part, on the determined identity of the RF transmitter.
2. The method of claim 1 , further comprising displaying the indication of the determined location of the mobile device relative to the lighting fixture within an enclosed structure.
3. The method of claim 1 , wherein the mobile device comprises a display for displaying the indication of the determined location of the mobile device.
4. The method of claim 1 , further comprising providing a service based on the determined location of the mobile device at the time the signal was received by the mobile device.
