What and Why

About Community Wireless Networks (CWNs)

A community wireless network (CWN) is an intranet for your geographic community, with one or more connections to the global internet. CWNs grow with communities - when two neighbors purchase one DSL link and share it using a wireless link between their houses, they have just built the smallest possible community wireless network. Even better is when ten neighbor households share two DSL lines and a cable modem line over a mesh wireless network, while using a virtual whiteboard (in the form of a wiki) to supplement their in-person neighborhood communications.

Why CWNs?

We believe that community wireless networks can simultaneously help bring geographic communities closer together while connecting them to people and resources all over the world. Municipal wireless networks, centrally-maintained cousins of community wireless networks, are growing in popularity - but they're prohibitively expensive to build and maintain. In contrast, CWNs can be started with a fairly small investment (~US$300-$500 and some time) and grown household by household.

We have begun to collect information and test solutions so that our members can build CWNs by deploying their own community wireless network nodes.
