Route diversity for microwave mesh network based on angular separation and link orientation

This paper discusses the rain attenuation experienced by a 26 GHz microwave link using real rainfall data and the route diversity of the mesh network based on the links´ angular separation and orientation. With the goal of optimizing the network configuration of mesh networks with the proper placement of relay nodes considering the rainfall attenuation, this study looks at how convergent path elements and a simple four-node square configuration of the mesh network will behave under rainfall conditions experienced at different locations. The rain data used in this study covers the whole country of Japan, making it possible to choose sites with climates that range from temperate to tropical. The link configurations studied showed significant diversity gain and gave insights about the area´s rainfall behavior.
