I always suggest a wired connection between networked patches because of latency and the potential of lost packets. I have some custom made shielded 40 mtr cat 6 cables that I use in the theatre for networking. Cat 6 is claimed to be good for 100-meter lengths. In my experience theatres tend to have a lot of network and electrical interference that can make critical wireless networks falter.
I believe one of the reasons for the introduction of timecode in Isadora was for accurate syncing of media.
