There is around 160 fablabs in France which is one of the most active country in the World.
Every big city has one or more fablabs but also small cities and even villages have one ! French people seems to be very enthusiastics…
So I think fablabs could be one of the best way to extend TTN in France.
In order to present this project to french fablabs (but also in every country) I have created a project here : https://www.fablabs.io/projects/the-things-network-building-a-fully-distributed-internet-of-things-data-infrastructure-in-france.
