Tetaneutral In English (Corbett)¶

tetaneutral.net is a non-profit ISP build by volunteers in the Toulouse area. It advocates for solidarity, net neutrality, freedom of speech, participative and cooperative management of the network, and teaching telecoms to the general public.

It is a set of wifi based Local Aera Networks (LAN) set up on the rooftops of several cities, connected to each other, directly (like the Toulouse / Saint Gaudens fiber link) or indirectly to and via the Internet (WAN or World Area Network), through ADSL, fiber or wifi. In short, it is an hybrid set up of independent and inter-dependent LAN/WAN networks.

It is mostly used as an activist alternative in big in the cities, and mostly as a rescue solution in remote villages where ADSL connection is poor or non-existent.

tetaneutral.net is a member of French Data Network (non-profit ISP federation).

The network¶

Looks centralized (it is in some part) because the software can't draw crossed links.

Here is a random database of pictures taken from the user's rooftops, if one can see his/her house from one of these picture, it means there is no obstacle to establish a radio link: http://pano.tetaneutral.net/data/tsf2/
