Coverage prediction issue in Atoll 3

[dacoder]

Hi,
I'm getting different result when doing coverage by signal level in Atoll ver 3 than in Atoll ver 2.
Here is the coverage in Ver 2:


and here is the coverage for same site in ver 3:


Both are coverage by signal level. Plz someone tell what am I doing wrong here??

Thanks

Wrong Frequency?
Wrong Antenna?
Wrong ERP power?
Wrong Model?
Different model?
Clutter not active?
Height not active?

Plenty of things can cause this..
Guess more info is needed

Hi,
I opened the same project file in ver3 that I was working with in ver 2. Do I need to do any modification before that?

Thanks

It seems treshold level, have you checks it?
And maybe heigths...

[berry001]

maybe the propagation model convertion from V2 to V3 is not correct.

How about map ? same map or different map with different resolution?

yeah i checked it...threshold level is same. I was wondering if the problem is due to DTM but that is loaded fine as well

using same map

Check these:
1- Geo>>Clutter Classes>> Properties.... check the values of heights and standard deviation.
2- Parameters>> Propagation Model... check the values of the specific model, is it same with old one?

By the way, what is the cell radius?

@dacoder

Possible solutions is all parameters are the same

1) Export data with v2 and import again in V3, not as project
2) Convert project with older version first
