Our continuing mission is to increase interest in the Radio Communication Series, and make sure that our readers are presented with relevant and timely material in a tutorial style. As radio communications are encompassing such a wide variety of technical topics, we are looking into contributions and technical activity in all relevant areas, and are seeking contributions from throughout the community of researchers and practitioners. To ensure that we are looking into the most significant topics, among other things, the editors have ventured into conferences and workshops to be in direct touch with potential and current readers.
