1. A system for providing awareness in a multi-space environment, the system comprising:
an array of gateway devices, each gateway device being positioned within a space in the multi-space environment, each gateway device having a gateway device identification providing an accurately-known fixed location;
a server in communication with the vertical and horizontal array of gateway devices, the server including:
a processor, and
a memory accessible to the processor, the memory including processor-executable instructions that, when executed, cause the processor to:
receive a plurality of gateway signals from a plurality of gateway devices of the array of gateway devices,
process the plurality of gateway signals, including a personal locator device identification and the gateway device identification for each of the plurality of gateway signals, with trilateration, the personal locator device identification originating from a wireless-enabled personal locator device,
process the plurality of gateway signals, including the personal locator device identification, the gateway device identification, and a received signal strength measurement for each of the plurality of gateway signals, with received signal strength modeling, and
determine an estimated location of the proximate wireless-enabled personal locator device.
