A position management system 1 includes an identification information transmitting apparatus 10, a relay mobile terminal 20, and a management apparatus 30, wherein the identification information transmitting apparatus 10 includes a power generating unit 12, an identification side storage unit 13, and an identification side transmitting unit 14 that wirelessly transmits an identification side signal using the electric power generated by the power generating unit 12, wherein the relay mobile terminal 20 includes a terminal side communication unit 21 and a terminal side communication unit 21 that wirelessly transmits a relay side signal, and wherein the management apparatus 30 includes a management side communication unit 31 and a management side control unit 33 that is based on the relay side signal received by the management side communication unit 31.

Disclosed are embodiments for estimating risk associated with a user of a wireless device. In some embodiments, the risk relates to a risk of infection by a contagious disease. For example, in some embodiments, the contagious disease is Coronavirus 2019. In some embodiments, locations of multiple wireless devices are estimated based on signal strengths of signals associated with the devices. Neighboring devices are identified based on highest probability regions of the devices that are determined based on associated signals. A measure of proximity to other devices is then determined based on probabilities that each device is located in neighboring regions. The risk is then based on the measure of proximity. In some embodiments, a risk of a first user associated with a first wireless device is based, in part, on a risk of a second user within a proximity of the first user.

A geolocationing system and method for providing awareness in a multi-space environment, such as a hospitality environment or educational environment, are presented. In one embodiment of the geolocationing system, an array of gateway devices is provided. Each gateway device includes a gateway device identification providing an accurately-known fixed location within the multi-space environment. Each gateway device includes a wireless transceiver that receives a beacon signal from a proximate wireless-enabled personal locator device. The gateway devices, in turn, send gateway signals to a server, which determines estimated location of the wireless-enabled personal locator device with transmitted signal strength modeling.
