[liberationtech] Mesh Networks?

I'm not dismissing mesh networks in general. I was specifically talking
about examples of municipal WiFi mesh networks like Rooftnet and Meraki. The
article you linked to is in reference to FabFi, which is an ad hoc
long-range radio network connecting to local meshes. My point was that
extending a local WiFi mesh to cover a large area (e.g. Kabul or Nairobi) is
difficult in practice. Other technologies might be better suited.

Just as a point of reference, FabFi's Nairobi installation serves 13 homes
and has only been able to operate at a peak of 1Mbps, which is 20% of their
capacity [1]. They averaged about 4GB of total traffic a day during April.
They are experiencing frequent outages as of a couple months ago [2]. That's
not surprising since power and network connectivity can be intermittent in
Nairobi.
