Heuristic occupancy and non-occupancy detection in a lighting system with multiple transmitters and a single receiver

A lighting system comprising:

• a light source;
• a plurality of wireless communication transmitters for wireless radio frequency (RF) spectrum transmissions in an area, including RF spectrum transmissions at a plurality of times;
• a wireless communication receiver configured to receive RF spectrum signals of transmissions from each of the plurality of transmitters through the area at the plurality of times, wherein the receiver is configured to generate an indicator data of a signal characteristic of the received RF spectrum signal from each of the plurality of transmitters at each of the plurality of times;
• and
• a control module coupled to the light source and coupled to obtain the indicator data of RF spectrum signals generated at each of the plurality of times from the receiver, wherein the control module is configured to:
• at each respective one of the plurality of times:
• apply one of a plurality heuristic algorithm coefficients to each indicator data from the receiver for the respective time,
• based on results of the applications of the coefficients to indicator data, generate an indicator data metric value for each of the indicator data from the receiver for the respective time,
• process the indicator data metric values to compute an output value;
• compare the output value at each of the plurality of times with a threshold to detect one of an occupancy condition or a non-occupancy condition in the area, and
• control the light source in response to the detected one of the occupancy condition or the non-occupancy condition in the area.
