Geolocationing system and method for use of same

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;
• each gateway device of the array including:
• a housing,
• a plurality of wireless transceivers associated with the housing, each of the plurality of wireless transceivers being part of a 2.4G multi-array of antennas,
• a processor located within the housing and coupled to the plurality of wireless transceivers,
• a memory accessible to the processor, the memory including processor-executable instructions that, when executed, cause the processor to:
• receive a beacon signal via the plurality of wireless transceivers from a proximate wireless-enabled personal locator device, the beacon signal including a personal locator device identification,
• measure phase differences between received incident of arrival of the beacon signal and a respective incident angle of departure of the beacon signal,
• transmit a gateway signal to a server, the gateway signal including the personal locator device identification, the gateway device identification, and angle of arrival measurement;
• and
• the server located within the multi-space environment and in communication with the array of gateway devices, the server receiving a plurality of gateway signals and measuring phase differences of the incident angles of arrival of each beacon signal and a respective incident angle of departure to determine estimated location of the proximate wireless-enabled personal location device.
