A wideband two-layer radio access network using DECT technology in the uplink

This article describes a novel architecture of a broadband radio access network using the two-layer network solution. The proposed downlink is compliant with the DVB-S standards, and a DECT custom solution is used in the return channel. The idea we present is based on the use of a "single carrier with equalization" system in order to directly link the end-user terminal, avoiding the most expensive part of the cabling network: the last mile. The article reports, some considerations concerning the advantages and disadvantages of the novel architecture. Successively, aspects such as frequency plan, architecture of the base station, local repeater, and user terminal, in combination with some practical studies, are discussed.
