Hi all,
I did the survey myself about tools and methodologies for UMTS planning.
It seems that most people in here familiar with one or two tools, including Aircom Enterprise, Atoll, Planet EV etc.
In principle, the tools mentioned above use emperical propagation channel model such as Hata model to predicte the propagation loss. To increase the reliablity of the prediction, the clutter database should be provided to describle the environment in detail, such as land usage, building, tree etc.
The other tools, such as Volcano of Siradel, WinProp, use the ray tracing method, in which the 3D digital map of the city is needed.
Can you comment the accuracy of these two methods in UMTS planning and how to improve the accurecy? If possible, can you provide the process in steps.
Cheers
