In densely populated areas, such as cities, it seems like it would be more advantageous to use shorter, faster presets, such as MediumSlow, MediumFast, ShortSlow, or ShortFast instead of the default LongFast.

How would you go about connecting these together without using the internet? I think MQTT could do it, but that would require at least one server somewhere that has no net connection and one radio for each speed. Is there another way that I might be missing?

I think you would also have to be careful with how much data you put onto the slower speed network.

Edit: example: MediumSlow is 82% faster than LongFast.
