Abstract
This paper presents a redundancy plan (1+1) based on millimetre wave (mmWave) backhaul links applied to a realistic network mimicking the Portuguese emergency communication system, in which the base stations (BSs) were selected according to favourable high ground elevation points with clear LOS between different BSs. The feasibility of establishing radio links between different BSs was analysed, not only in term of maximum range limited by the signal attenuation and system sensitivity, but also in terms of Fresnel Zones clearance. A shortest-path algorithm was then used to process all valid radio link and generate a redundancy plan in a tree topology. Finally, the shortest-path algorithm was used with specific constraints, to generate a redundancy plan (1+1).
