Important! So you know what you were saying about the problems with mesh networking in a smaller space?

Just make sure to specifically buy models that have smaller antennas and lower transmit power so that you’ll minimize the cellular interference issue.
Also noted is the advent of more “consumer friendly” wireless mesh network systems.
