Introduction
Radio network optimization is carried out in order to improve the network performance with the existing resources. The main purpose is to increase the utilization of the network resources, solve the existing and potential problems on the network and identify the probable solutions for future network planning.
Through Radio Network Optimization, the service quality and resources usage of the network are greatly improved and the balance among coverage, capacity and quality is achieved.
In general, the following steps are followed during the Radio Network Optimization:
• Data Collection and verification
• Data analysis
• Parameter and hardware adjustment
• Optimization result confirmation and reporting.
Due to the mobility of subscribers and complexity of the radio wave propagation, most of network problems are caused by increasing subscribers and the changing environment.
Radio Network Optimization is a continuous process that is required as the network evolves.
Causes that inspire carrying out the RN optimization:
• New network or expansion on the existing network
• The network quality decreased seriously and there are many complaints from subscribers.
• An event occurs suddenly which affects the network performance seriously.
• The number of subscribers increased and affects the network performance gradually.
Inputs for optimization
• Traffic statistics
• Drive test
• Customer complaints
