The increasing consumer demand for mobile data which will further accelerate with the introduction of 5G has obliged operators to upgrade their network capacity. To that end, one of the most effective approaches is to enhance the spatial reuse of limited spectrum through dense deployment of small cells to complement existing macrocellular networks. Small cells are low-powered radio access nodes which have a range from 10 meters to a few hundred metres. They are deployed on public and private infrastructure within the urban environment. Typical deployment sites include pole tops (e.g., street lighting, traffic lights, telco poles, etc.), bus stops, and building walls.
