Adaptive beamforming for cellular base stations

This paper gives a general overview of the work of the Eindhoven University of Technology that is carrier out within PANAMA European project. This project addresses the future communication needs in Europe related to increased e??ciency and energy saving in applications such as cellular handsets, base stations and mobile satellite communications. Additionally, the paper describes the need for adaptive beamforming for downtilt in base transceiver stations and the novel approach to tackle this issue using phase shifters based on RF MEMS
