Your average street in the UK is going to have a large number of wireless networks, all secured, with a single use scenario. Oh dear....
When all these single-use networks go bang (it only takes the BT network to have issues), you are in the proverbial :(
The Serval Mesh project implements a mesh network of mobile phones consisting primarily of wifi hot-spots. Serval Mesh has been utilised in an emergency (where infrastructure is not-available) situation.
But, I have always wanted to apply the Serval Mesh model to a typical UK street. If you had a mesh network, which consisted of wifi-hotspots, and access-points - you may have a useable network.
This idea is not new, but the Serval Mesh project has (re-)ignited my interest. The network would be there for regular operation, but importantly in an emergency.
Thinking about infrastructure contingency is important. It’s the reason I carry a torch in my rucksack, useful if there is a power outage.
This subject fits neatly into the self-sufficiency way of thinking. Because shareholders take priority over investing in infrastructure. The "general" (and it should not be "just-for-geeks) population should be able to stand-on-there-own-two-feet.
