Our radios are code division muliplexed. You will not be able to draw a conclusion from a spectrum analyzer. This is a question for some smart grad student in electrical engineering who is specializing in digital telecommunications. The problem can be modeled with a computer simulation. As I said before, I believe that range will be reduced as the number of users increases. But I am not sure if this will start to be seen at 100 users, 1000 or 10,000.
