This report is the outcome of the project “BojKom”, financed by Trafikverket, and done at the department of Electro and Information Technology at Lund University. It has investigated the feasibilityof including a higher degree of wireless communication in Swedish Sjos¨ akerhetsanordningar ¨ (SSA), corresponding to the english Aids to Navigation (AtoN), and the possibilities that would come with such a development. The study has been done by a literature review, and interviews with organizations that have been identified. Further input was collected at a workshop at the end of the project. The report is organized to give an overview of the state of the art, and to outline how the developmentcan proceed from here. The aim of the study was to make an inventory of possible use cases, and toidentify the most interesting avenues to explore. In the report we are using the term buoy for floating AtoNs specifically. UAV stands for Unmanned Aerial Vehicle, which can be both of the type with multiple rotors, or having a fixed wing. USV for unmanned surface vehicle, or small boats, which typically in this context are smaller and not designedprimarily to transport persons or larger cargo. Both UAV and USV can have autonomous capabilities, such as autopilotsm, to various degrees on board.
