It is always more accurate and efficient to have good CAD drawings of the building. This will make it a lot easier to do the signal benchmarking and to take the benchmarking data and place it onto a map so that we can show you, in a very visual way, where the antennas should go, where the coverage is strong in the building already and where it needs to be improved.
So CAD drawings, if they’re available, are very important. It also helps to know what your environment looks like in terms of number of users you have for each carrier. Those are really the two deatils that are most important.
