In this paper, the design, building, and functioning of a complete communication system with 16 antenna elements, software-defined radio, and beam-tracking capabilities for up to four users is reported. Since the design uses components off the shelf, it is relatively low cost, which makes it feasible to be used in high-volume commercial applications. A key feature is that all digital beamforming and advanced direction-of-arrival tracking algorithms are integrated into one segment-the multiple users beam tracker. Experimental results with regard to system performance, responding time, and efficiency illustrate the effectiveness of the concept.
