Radio Network Planning Tools Basics
The Network Processor
• produces network-wide results out of the singlecell-based results
• allows to analyse the radio network
BS1
• allows to simulate changes of the network
parameter
BS2
• allows to simulate changes of the network design
• allows to optimise the radio network
BS3
• allows to plan the future roll-out phases
• produces statistics on the selected results
