#dot:dot 4+

#dot:dot is the companion app of a WiFi mesh network made of small electronic boards called “#dot’s”, that can be purchased from the DotDot S.A.S. company. The said WiFi network bears “#dot:dot” as SSID: it is an ad-hoc, inter-operable, self-healing, SIM-less and non supervised mesh network.
When switched on, each #dot is seeking and connecting to its peers, without any human intervention. The #dot nodes create an ambient off-grid 2.4GHz WiFi network that can be detected with a smartphone, i.e. a WiFi network with no internet access.
Users who have the password of the private #dot:dot network car connect to the #dot:dot WiFi: their phone is connecting to one of the #dot nodes (usually the one with which the RSSI is highest, this being managed without user intervention).
Once connected to the #dot:dot mesh network, users can open the #dot:dot app, and access to the following functionalities:


In off-grid mode, users can use the chat function and exchange text messages, images or videos with any user connected to the same #dot:dot mesh network
In WiFi repeater mode, users can link the #dot:dot mesh network to a 2.4GHz WiFi gateway, and enjoy internet access even from a distance to the said gateway, in a local zone where the said gateway is not accessible
In any mode, users can visualize in real time the topology and status of the mesh network to which their smartphone is connected
Information and FAQ’s on what is the #dot:dot mesh network.

#dot’s are pocket-size devices, so they can easily be carried by users: as users move, the mesh reconfigures by itself without intervention to optimize the throughput between nodes. Said throughput is between 1 and 12 Mbps.
