Location services using multiple light fixtures

A system comprising:

• an object comprising a communication device, wherein the communication device of the object broadcasts a first radio frequency signal from a first location within a volume of space at a first time;
• a first light fixture disposed at a first light fixture location in the volume of space and comprising at least one first light source, a first antenna, and a first receiver, wherein the first receiver, using the first antenna, receives the first radio frequency signal, wherein the at least one first light source provides a first general illumination to the volume of space, wherein the first receiver receiving the first radio frequency signal is independent of the at least one first light source providing the first general illumination to the volume of space;
• a second light fixture disposed at a second light fixture location in the volume of space, wherein the second light fixture comprises at least one second light source, a second antenna, and a second receiver, wherein the second receiver, using the second antenna, receives the first radio frequency signal, wherein the at least one second light source provides a second general illumination to the volume of space, wherein the second receiver receiving the first radio frequency signal is independent of the at least one second light source providing the second general illumination to the volume of space;
• and
• a controller communicably coupled to the first light fixture and the second light fixture, wherein the controller:
• determines a first strength of the first radio frequency signal received by the first receiver;
• determines a second strength of the first radio frequency signal received by the second receiver;
• determines a difference between the first strength of the first radio frequency signal received by the first receiver relative to the second strength of the first radio frequency signal received by the second receiver based on a first distance between the first light fixture location of the first light fixture and the second light fixture location of the second light fixture and starting a time period;
• scales a location of the object in a first plane using the difference between the first strength of the first radio frequency signal and the second strength of the first radio frequency signal;
• scales a location of the object in a second plane using the difference between the first strength of the first radio frequency signal and the second strength of the first radio frequency signal;
• and
• determines a location of the object in the volume of space based on scaling the location of the object in the first plane and scaling the location of the object in the second plane.
