When running in squared circles, the mind wanders ...

Considering how dependent we are on the internet, cell phones, landlines, mass media, etc., what if these no longer worked? Is this not a no-communication emergency?!
Obviously, the first step in no-communication emergencies: identify who's got the info and how to get/share it. If you haven't a clue now, consider a panicked city full of clueless people: "It was the best of times, it was the worst of times ..."

Assuming that electricty (or batteries) are available, some computer technology might be useable - it may be possible to assemble a non-internet, WIFI-connected, Private Neighborhood Internet (PNI); basically a community bulletin board where information is shared.
If it were possible to WiFi-connect a neighborhood of selected computers, without any of those computers needing internet access, a PNI might be worthy and reliable communication backup. Information shared might be sensitive - encryption would be a necessary option and access to the PNI limited to reliable participants/systems.

But typical network range seems limited ...

Apparently, typical range is quite limited (relative to cell phones and towers), but range might be extended in creative ways. Just having electronic access to a community bulletin board where one or more participants can share information from other sources is a definite plus!

However, range is not necessarily a severe limitation ...

"A typical wireless router in an indoor point-to-multipoint arrangement using 802.11b or 802.11g and a stock antenna might have a range of 32 metres (105 ft). Outdoor point-to-point arrangements, through use of directional antennae, can be extended with many kilometers between stations."

Therefore (seems to me) ...
A PNI simply requires planning, investment, and effort! The technology already exists (apparently). In fact, the greater challenge may be administration of the PNI (who participates, who pays for what, how the network is used, bandwidth limitations, etc.).

So, What's the point? ...
This is an opportunity to market products/services supporting a local PNI; local PNIs might interconnect to create a regional network.

BTW: a PNI is a local community network - not a business VPN (apparently).
Just wandering ...
