[Commotion-discuss] Building a commotion network to support 2000 concurrent users

[Ben West]

My recommendation, from operating a mesh network with firmware very similar
to Commotion, that serves ~100 people daily, would be to focus on how many
mesh nodes you would need to deploy.  Likewise, since there is no way to
fit 2000 users on a single 2.4GHz channel, you would be needing to segment
such a large deployment into pocket meshes, e.g. a handful of nodes in each
mesh, with adjacent meshes programmed to non-overlapping channels.
Backhaul between these pocket meshes could be done with 5.8GHz radios, or
wired backhaul depending on your situation.

To help with estimating how many nodes you'd need, it's fair to assume each
node could only support up to 5 (or possibly 10) simultaneous clients
before either the node itself exhausts its RAM (only 32Mbytes onboard
memory) or before the particular channel used by that ( node + its
neighboring nodes + all clients ) becomes saturated.
