High capacity digital radio relay systems for the 18 GHz band
Abstract
The paper presents a new high-capacity radio relay system family for the 18 GHz band designed for use in local and regional networks. Indirect modulation and advanced SAW filter technology permit up to 560 Mb/s per RF channel to be transmitted and enable up to 4480 Mb/s band capacities to be realized with maximum spectrum efficiencies of 6.8 b/s/Hz. The present system family is an attractive transmission concept for route extensions and frequency coordination in densely meshed networks.
