Cells & parameters in order of relevance Parameter2 (eg azimuth) Parameter1 (eg tilt)

Network improvement Improves radio environment with secured coverage and maximized network quality and capacity. Efficiency Gains Speed – runs faster than manual process. Depends on a few factors: PC performance, Size of area to optimise, Resolution of data and number of changes Minimal user input – lower cost of service, focus on high margin work Accurate Modelling Predictions are more realistic than planning tool because based on real drivedata.

Garbage in, Garbage out Poor propagation model will be a problem in design phase Key: Input data needs to be accurate and complete Drive data should be thorough for higher accuracy Need to control changes Eg don’t uptilt boomer sites Need to review changes some can be aggressive
