As for courses specifically relating to that the CUWSS is an obvious one, however you may want to look at Air Magnet aswell.
It all depends what tools you have available. WCS > Planning Mode or AirMagnet Planner.
Thank you for your answers guys.
I have access to both WCS and AirMagnet. Alltho I can't find any AirMagnet courses in Sweden, but I will look in to CUWSS.
