Abstract
A system for managing data related to at least one leaf node device includes a location processing engine located on a server that is remote from the leaf node device, at least one point of interest (POI) device for collecting data via Bluetooth Low Energy (BLE) communication signals from the leaf node device on each of a plurality of channels and transmitting the collected data which includes phase angle information, a reader node device for receiving and transmitting the collected data to the location processing engine and a database of the known locations of a plurality of POI devices. The reader device or the location processing engine averages the collected data across the plurality of channels, and the known locations are used along with the averaged data as a basis for determining the location of the leaf node device.
