Systems, methods and devices for asset status determination

A system for determining a real time location of a leaf node device, the system comprising:

• at least one battery-powered Bluetooth Low Energy (BLE) enabled leaf node device, wherein the at least one leaf node device is associated with a corresponding monitored asset, wherein the at least one leaf node device transmits data via BLE communication signals on each channel of a plurality of channels, wherein each channel comprises a different frequency band;
• and
• at least two beam forming reader nodes in communication, via BLE communication signals, with the at least one leaf node, each of the reader nodes including a corresponding plurality of antenna elements for producing a corresponding specific radiation pattern of a plurality of sectorized beams in a corresponding plurality of sectors, wherein each of the reader nodes is enabled to receive communication signals in each sector of its corresponding plurality of sectors on each of the plurality of channels, and wherein each of the reader nodes collects, in at least one sector common to both of the corresponding plurality of sectors, corresponding signal strength data from the at least one leaf node device in the at least one common sector from at least two different sectorized beams of its corresponding plurality of sectorized beams at the same time,
• wherein a location processing facility determines the presence of the at least one leaf node device in the at least one common sector and the real-time location of the at least one leaf node device in the at least one common sector based on the corresponding signal strength data from the corresponding at least two different sectorized beams collected by each of the at least two beam forming reader nodes and based on a triangulation calculation.
