The mailing list for users of the eduroam Configuration Assistant Tool (CAT)

Over a decade of stats tells us that you approx. 7% of your roaming
visitors will be international ones.

Most of those will come with their devices pre-configured at home. Only
those who did not do that will stumble into the walled garden. If we
assume 5% that makes 0.35% of total roaming visitors using your captive
system.

Germany is the only NRO who deploy their own CAT instance. The fraction
of German users on your university various on the research and exchange
profiles you have with Germany, so it's impossible to predict exact
numbers. In terms of orders of magnitute, maybe one in every ten
thousand roaming visitors at your campus will have problems.

If you have 10.000 roaming users per day, that's one every day. But
maybe you have less than that :-)

Our world would be a lot less complex without Android :-)
