• Network simulation – Coverage, interference, quality • Capacity Planning – Cell dimensioning, load balancing • Parameter planning – Neighbor list optimization, code planning (e.g., PCI, PRACH, RSI) • Design optimization – What-if scenario simulations and network design optimization based on traffic and ROI At the very highest level, planning tools need to fulfil 4 key use cases:
To achieve these use cases, requires a planning tool which has the following core capabilities at least:
1. What-if scenario planning and automatic site selection: When deploying mmWave, contiguous coverage is not the primary aim. The aim is to deploy sites where they will absorb the most traffic from the other carrier layers and where the extra bandwidth will have maximum impact on subscriber QoE. To achieve this, requires a planning tool with scenario planning and automatic site selection based on multiple data inputs including network traffic (throughput and volume), ARPU maps and more. A data-driven approach is required. 2. 3D planning: Planning in 2D is no longer sufficient. Subscribers want to be able to use their phones in high-rise buildings, emergency services need to use their phones on helipads on top of hospitals, and command and control of drones is rapidly growing into a lucrative market for mobile network operators. To ensure the network can meet these use cases requires a planning tool that supports 3D planning including 3D site selection and optimization, 3D beamforming analysis and 3D network statistics.
