I've said this a few times.... meshtastic's achillies heel is that every device is a repeater. When you have more than about 15 units in vicinity to one another, when one person transmits a message, for the next few moments the network is 100% saturated as every nearby station retransmits the same thing. It's great in a small group but not for >15 or so users.

I saw a post tonight about the Atlanta area "Atlanta area is all on MediumFast now. Most everything in GA above I-20 is MediumFast, below I-20 is still LongFast. Seems to be the dividing line."

Their solution is to divide the network into two different speeds which are incompatible with each other. 1)this makes communications over a large area impossible due to the different settings, 2)how is a user to know when to change frequency/modes? In the end, they will experience the same problem again as growth continues.

Meshtastic cannot scale. Meshcore does because it is more structured.

When you transmit a message in meshcore, it is repeated once by a high up repeater and potentially 100s of users hear that ONE transmission. It's a huge difference in efficiency and battery saving.
