Accurate propagation studies require a lot more than just submitting coordinates, heights and frequencies. You really can't just use some set of default numbers for all the parameters involved. You need antenna patterns, gains (on both ends), C/I values, noise figures, and a whole host of other info. This doesn't even include optimizing for clutter categories and elevations. If you don't have this, you might as well just draw circles as it would be about as useful. I spent a lot of years making good money doing just this for the cellular industry. They understood that designing a network incorrectly had dire financial consequences. We on the other hand seem to think of prop studies as an after thought. While I know that we have to go where the towers are and don't have the resources to build where we want to get an optimized network, we should still take it seriously and do it right when we decide to actually perform the study.
