Upon switching them on, the #dot nodes spontaneously scan their neighborhood in search for peers to connect to: without any human intervention, they connect to one another dynamically, and form an ambient WiFi network detectable with a smartphone or computer.
This #dot:dot WiFi network is - by construction - NOT connected to the internet: it is a private and protected network that can be used for local data transfer, e.g. for military operations.
Via the #dot:dot app, one can further connect the #dot:dot WiFi network to any gateway: public hotspot, home WiFi, shared mobile connexion... by providing the #dot:dot network with the relevant SSID and password of the gateway. Once connected to a gateway, all #dot nodes give access to the internet.
