Cognitive Motion-Dynamic Tethering of a Phased Array to an Android Smartphone

An interactive framework for cognitive radio applications is proposed in which a user-equipped Android smartphone and a phased array controller are wirelessly tethered. Algorithms on the smartphone pull inertial, geolocation, and networking data to coordinate tracking and beamsteering, and the smartphone itself serves as a wireless communications bridge between the phased array´s control module and a remote network server which facilitates bi-directional communication of health monitoring data, state information, and control signals. The system architecture, algorithms, and measured results from beam-steering of a 4 × 4 micro strip patch array via the Android smartphone are discussed.
