As mobile network capacity demand increases rapidly, a lot of the operator's investments are directed to optical distribution networks for radio access network (RAN) transport. However, even with its high capacity, optical fiber networks are not always the best option due to its costs, and possible delay in the time required to build it. This paper explains the steps of planning and deployment of 5G radio-relay line. Firstly, a link budget and fading margin calculations are analysed. Secondly, a profile of individual routes are established. Finally, based on the experiments carried out we proposed the structure of the urban radio relay network.
