[Berlin-wireless] Alternate radio internet network

So Mär 27 22:40:42 CEST 2022

Thanks very much.

I will definitely look in to all that.

Because I’m so new to this I think I have to clarify or focus my question a
bit.

You mentioned some pre-existing “ad hoc” networks such as “Babel”.

Are those examples of sort of “peer to peer” internet networks? Which is
the most widely used and established current one? I’d like to try to join
their network to get a sense for what it’s like to use.

It should be a network of computer devices spread out over an area, each
communicating with each other wirelessly, each person controlling their own
wireless device, and not utilizing any commercial internet infrastructures
in between, like cables installed in the ground by companies.

Thanks very much,
Julius
