Distributed Network Configuration with Multiple Antenna Beams: A New Concept for Secure, Distance-Selective Wireless Communications

This paper introduces a novel network configuration that is based on a digital modulation where each bit is transmitted to a different spatial direction at the same or different intervals of time. In order to receive the signal, the receiving antennas need to be placed at proper distances from each other. These distances are proportional to the distance from the transmitting antenna, referred to as the distance of operation. The distance of operation can be selected as desired, within physical constraints, and is a function of the isolation between the lobes. A case example is discussed to illustrate the new configuration in conceptual form, and security issues currently under study are briefly addressed
