We have a very active DMR network in Indiana with dozens of repeaters on the network. We have learned the repeater folks are being told worst case scenarios. Our first repeater we put online we were told they needed a 3megx1meg constant connection. Once it was online and getting heavily used we are seeing spike of 512k, and this is a repeater that is very heavily used. Attached is a usage graph of what is called a Cbridge server. This is basically a soft switch for these repeaters. This particular server has a couple dozen very active repeaters talking to it. So this is real world bandwidth usage with a couple dozen DMR repeaters talking to a single source.

I support our local HAM group and have allowed them to place repeaters on two of my towers at no charge to their group. Now one of their members has asked for Internet service at one of the sites for HAM use. I have heard something about HAMs using the Internet to "talk" so I guess this is not unusual. For me the kicker is that he is asking for 20x20Mbps service...I certainly have the capacity but that just seems excessive. Opinions anyone?
