Consume.net are doing some interesting work with wireless networking,
they plan to network the whole of London, with users providing their
own nodes, thus doing away with the conventional ISP/user model.
They propose a number of wireless technologies for interlinking.
>From the comments:
As I see it, the normal wired connection is equivalent to the
dinosaurs a few million years ago and the wireless methods are those
furry little mammals that eventually dominated this planet.
Eventually there will be few if any wired connections and wireless
will be the standard for data communications. There may well be an
issue with available bandwidth if huge numbers of these nodes are
used. There is only so much bandwidth available in these RF bands.
Like trying to get any real use from a CB radio a few years back
with all the high powered SSB and the huge numbers of users.

It's not trivial to make a surviveable network out of unreliable
radio links, or to optimize the routing. I don't think Ricochet does
anything so bright. Some years ago I wrote a protocol called RSPF
for IP route computation over packet radio networks. Craig Small's
implementation is in SUSE Linux. I don't know how well it would work
on a large scale.
There are a number of links in the article and comments; the ones I
haven't seen before follow:
each node has a router which routes (der) and serves as a container
for the mediating software which is router based. It should also
contain a small web server which publicises the legal frame work of
the network and the conditions for usage (npl).
Grid is a system for routing in wireless ad hoc mobile networks
being developed by MIT LCS's Parallel and Distributed Operating
Systems group. Grid combines the GLS distributed location service
with geographic forwarding to provide a robust and scalable network
fabric for wireless mobile computers and devices. Grid does not
require any fixed infrastructure such as base stations.

SeattleWireless to end recurrent telco fees. This is a
not-for-profit venture. It is an effort to conceive, create and
deploy a complete wireless community network. Much as the Internet
started by plugging several networks together, it is our goal to
create a wireless backbone. This can be accomplished using the
technology that is available today. Do not be fooled by the
corporate effort to deploy this technology in a lesser fashion.
Bluetooth and devices like the Apple Airport are primarily designed
for 'home networking', but wireless networking should not be limited
to the home. Bluetooth devices do not appear to allow for uses
outside their scope, but the 802.11 AppleAirport contains the exact
same wireless card as the Lucent Access Points.

Since SeattleWireless would not exist without collaborative effort,
and a healthy dose of anarchy, the entire site is in PikiPiki. You

* Compared to traditional cabled LAN, the initial investment
in a FiRLAN system offers a competitive alternative,
without the large incremental costs associated with cable
maintenance and relocation.

I work for a company that sell wireless LANs. I the past 9 months,
over 75 percent of our sales calls have been from ISPs implementing
wireless LAN technology to deliver internet services to customers.
Unfortunately, most of them know little about the technology and are
not interested in engineering a wireless network that delivers a
constant bandwidth with high reliability.

This was tried twice in Silicon Valley in the early 1990s. Once by
Dewayne Hendricks, who wanted to put a node at every library to
cover the surrounding area, and once by Tom Jennings, the designer
of FidoNet, as The Little Garden, an early ISP. Some of us at
Stanford even looked into this in the late 1980s, but nothing came
