Abstract

Systems and methods according to one or more embodiments are provided for routing wireless mobile communication signals using a phased array communication network. In one example, a system includes a plurality of phased array antennas configured to receive an RF modulated data packet. The RF modulated data packet includes a header and payload data. A demodulator circuit is provided to demodulate the header to identify route information while maintaining the payload data in RF modulated format. The phased array antennas are configured to transmit a high bandwidth narrow antenna beam comprising the RF modulated data packet in accordance with the route information. Maintaining the payload data in RF modulated format during the route provides for high bandwidth and high data rate transmission required of today'"'"'s wireless mobile communication networks.
