1. A phased array powered wireless gateway (“PWG”) device comprising:
a phased array configured to receive a plurality of received signals transmitted by two or more railcar-based communications management units (“CMUs”), and wherein each said railcar-based CMU is disposed on a respective railcar of a plurality of railcars;
a phase detector in communication with the phased array and configured to detect vector information from the plurality of received signals; and
a microprocessor that has a fixed position in a geographic area, is in communication with the phased array and the phase detector, and is configured to determine a location of each railcar-based CMU and to detect a direction of propagation of electromagnetic radiation emitted from each said railcar-based CMU, and determine an order of railcars in a train consist based on the directions of propagation which were detected.
