Abstract
Technologies directed to coordinated dynamic analog beamforming are described. One method includes receiving, by a digital controller of a first wireless device, a data packet, the data packet comprising a destination address of a second wireless device. The method further includes retrieving, from memory, beamformer configuration data associated with the destination address, the beamformer configuration data comprising a phase shifter angle value for a radiation pattern. The method sends, to a beamformer circuit, the phase shifter angle value, the beamformer circuit comprises a power splitter and a set of phase shifters (e.g., at least four). The method causes the set of phase shifters to steer the radiation pattern of electromagnetic energy, radiated by an antenna array of elements, at the phase shifter angle value and sends the data packet to the second wireless device via the antenna array.
