Dear experts

I'd like to use the following setup for clear separation of FOH and stage onitoring:

a) all Inputs signals are split into two signals, going into a) and b)

a) Stage Monitoring
- RM32, connected to Wireless router A
- multiple iPads connected to let musicians control their stage monitoring channels

b) FOH
- RML32, connected via Motu AVB to Wireless Router B
- one iPad to wireless Router B
- CS18ai to ABV (optional, maybe we use iPad only for FOH mixing)

We'd like to use this setup instead of cascading the mixers for clear separation; e.g. musicians do not see FOH setup and can't change by mistake. So does the FOH sound engineer, he doesn't see monitoring at all.

Never tried this; do you experts see any issue with this kind of setup? (In particular with two WIFI router placed closely to each other).
We could also think of using just only one WIFI router and not using CS18ai.

Would be thankful for any advice.

Thanks
Rainer
