The low bandwidth and the mesh topology put a hard upper limit on the number of nodes in a channel. From memory its limited to 250 nodes in the default settings. https://meshtastic.discourse.group/t/theoretical-mesh-stats/217 https://meshtastic.discourse.group/t/theoretical-mesh-stats/... "I suspect up to about 30 nodes per channel would be fine, I bet the channel will be almost unusable once you reach 100 nodes." As for voice - I think in default "very long range mode" the mesh bandwidth is down around 20 bytes per second. It's possible to get higher bandwidth at the expense of range, but it's really not what you're looking for if you want voice comms.
