Radio access network optimisation (RAN optimisation) can be defined as the set of activities that are required in an already active wireless communications network in order to improve or maintain performance.

Overview of RAN Optimisation

Radio Access Network (RAN) Optimisation is a critical process in modern mobile networks. It ensures that the network provides optimal coverage, capacity, and quality of service. This involves a continuous process of adjusting and fine-tuning network parameters to adapt to changing user demands and technological advancements. RAN optimisation aims to enhance user experience by reducing dropped calls, improving data throughput, and ensuring consistent network availability across different geographic areas.


Goals and Strategies in RAN Optimisation

The primary goals of RAN Optimisation include enhancing subscriber satisfaction and minimising network issues. This involves a strategic approach to manage network resources efficiently, such as optimising cell site location and configuration. Key strategies include detailed network planning to prevent overloading, dynamic adjustment of network parameters for optimal performance, and using predictive analysis to anticipate future network demands. These strategies help in reducing operational costs and avoiding unnecessary expansion of network infrastructure.

Tools and Techniques for RAN Optimisation

The use of cutting-edge tools like Atoll and its modules illustrates the technological advancements in RAN optimisation. The Atoll Live module goes beyond traditional data analysis, utilising live network data to facilitate analysis and automated adjustments. Its Automatic Cell Planning (ACP) module leverages sophisticated algorithms for efficient cell site planning, considering various factors like terrain, user density, and existing infrastructure. These tools leverage a mix of simulations, field measurements, and user data to identify and resolve network congestion, adjust antenna configurations, and refine neighbour relationships, ensuring the network operates at its peak efficiency.
