1. A gateway device positioned within a space in a multi-space environment for providing awareness in the multi-space environment, the gateway device comprising:
a housing,
a wireless transceiver associated with the housing,
a processor located within the housing and coupled to the wireless transceiver,
a memory accessible to the processor, the memory including a gateway device identification providing an accurately-known fixed location, the memory including processor-executable instructions that, when executed, cause the processor to:
receive a beacon signal via the wireless transceiver from a proximate wireless-enabled personal locator device, the beacon signal including a personal locator device identification and transmitted signal strength identification,
measure received signal strength of the beacon signal,
transmit a gateway signal to a server, the gateway signal including the personal locator device identification, the gateway device identification, the transmitted signal strength identification, and the received signal strength measurement; and
an estimated location of the proximate wireless-enabled personal locator device determined by the gateway signal utilizing trilateration, received signal strength modeling, and transmitted signal strength modeling.
