Techopedia Explains Smart Antenna

Smart antennas can be part of systems like reconfigurable broadband and next-generation wireless systems. Solutions like beamforming help to direct signal transmission in specific ways. Two different types of smart antennas, switched beam smart antennas and adaptive array antennas, work in different ways. In general, smart antennas help to specialize signal transmissions for efficiency and other benefits. They "beam" signals in targeted ways, to make the generalized antenna output more precise.
