The question is whether it uses Ethernet addressing and offers an Ethernet-compatible MAC layer API, and 802.11 certainly does.  You can run SimH Ethernet just fine over a wireless LAN.  I've run PDP11 SimH that way with no problems.

Actually, I have run into problems. The broadcast domain, as well as the 
Unicast have slight differences to Ethernet, which makes it sometimes 
fail in subtle ways.
Having a second mac address on a WiFi interface, one that is used by 
simh, though tun/tap, does not work that well with WiFi. Unfortunately.

I've definitely had problems keeping it working under OS X at least. And 
I'm pretty sure I've read of others having the same problem.
