Beamforming antennas are an essential tool for mobile operators as they build out their networks for capacity and 5G NR. For radio planners tasked with developing 5G and capacity build-out strategies, it is critical to have a full understanding of beamforming antenna capabilities, including the variations and appropriate use cases for each type. Without this understanding, planners risk over- or under-engineering parts of their networks, resulting in unnecessary costs, insufficient performance, or both.
