First Claim
1. A method for commissioning one of a plurality of RF communication devices, comprising:
- repeating for a number of iterations at indiscriminate locations within a service area, an iteration of the number of iterations, comprising;
moving a portable processor-controlled, radio frequency (RF) receiver-equipped device to an indiscriminate location within the service area for the iteration;
estimating the indiscriminate location of the portable device within the service area using a secondary location estimating system supported by the portable device, wherein each iteration produces a different estimated indiscriminate location at a different location within the service area;
storing the estimated indiscriminate location for the iteration in a memory as a ground truth position of the portable device;
collecting, by the RF receiver of the portable device, an RF communication device identifying signal transmitted by one RF communication device from among the plurality of RF communication devices in the service area, wherein the one RF communication device is being commissioned in a primary system network including the plurality of RF communication devices;
obtaining from the collected RF communication device identifying signal an RF communication device identifier of the one RF communication device; and
determining a received signal strength indication (RSSI) value of the collected, RF communication device identifying signal for the iteration; and
storing the RF communication device identifier, in the memory, in association with the respective RSSI value and the estimated indiscriminate location for the iteration; and
after the number of iterations, the commissioning comprises;
calculating, by a primary location determination service, a location in the service area of the one RF communication device being commissioned in the primary system network based on, from each of the number of iterations, the determined RSSI values and the estimated indiscriminate location of the portable device, using the secondary location estimation system, for the respective iteration stored in the memory in association with the RF communication device identifier of the one RF communication device being commissioned in the primary system network.

Abstract
A system includes radio frequency (RF) communication devices, for example, in luminaires, located in a service area offering a location determination service, and a portable device used in commissioning the communication devices. The communication devices transmit a primary location determination system'"'"'s RF signals for receipt by the portable device. The portable device determines its location using a secondary system. The RF communication devices'"'"' transmitted RF signals include an identifier. A received signal strength indication (RSSI) of each signal received by the portable device is measured, and stored with an estimate of the portable device'"'"'s corresponding location. The portable device is moved to another location to measure RSSI of RF signals. When the number of measurements or number of locations is sufficient, the locations of each of the respective luminaires or communication devices may be determined using the RSSI values and the portable device'"'"'s estimated indiscriminate location.
