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