I didn’t respond the first message but the mention of 4G seems to be
going in the wrong direction. The idea of connecting devices is of
course very old. Even BSR X10 (originally to control their
turntables) is in this category.
The problem with the “4G” framing is not the technology itself but
in that misses the point of the Internet by increasing the coupling
between system elements rather than reducing it. It makes great press
since people can identify with gee whiz applications but it’s not
very different from the homes of the future we’ve seen for decades
with chatty toaster ovens.
We wind up with protocols that build in the application architecture
such as Bluetooth and CEBus. And we give up control to the phone
companies in trade for having them make the cellular phones do all
sorts of wonderful things that we couldn’t possibly do ourselves.
Actually we can but that’s too much of a threat to their control to
be tolerated. 3G makes cellular calls billable whereas meshed VoIP
would deny them our money.
One of the reasons I want to move beyond the DNS and IPv6 is to
support light switches and other mundane devices. The devices need
their own identities – both logical and intrinsic. You don’t
really want to depend on an external registry in order to address
your light switches. You also need to be able to set access and other
policies so you could do something as simple as setting rules for
sharing a light over a common driveway. Here too you need to avoid
depending upon third party services for identity and vouching.
Setting up interacting policies and trying to make them match our
intent is a very difficult problem but it’s not about the low level
technologies, it’s about system architecture and social issues.
For that matter, the lack of mobility is also a problem of policy and
protocols. Speed is nice but getting any connectivity is the biggest
step.
I have no problem with developing new technologies – but I worry
when we great new dependencies and confuse a communications mesh with
a ball of knotted twine. The problem is not speed. You don’t need
100mbps to connect your teapot to your toilet.

How about a couple of months ago, here in Japan? Your teapot and toilet
can already snitch on you via the Net, see

How much more ubiquitous do you need? (I know, there's still a ton of
work to do, and many tons of equipment to manufacture, sell, and
install.)

Fixed or mobile? I would guess that here in Japan the average *new*
installation is 100Mbps, today. It'll be a few years before everybody
catches up, of course.
Mobile, a number of research groups planet-wide are working on 4G. One
such is the Nakagawa Lab at Keio, supported in part by Nokia:

http://www.nokia.com/link?cid=EDITORIAL_1285
Prof. Nakagawa is working on Orthogonal Frequency Division Multiplexing
(OFDM), along with a variety of other things. The roadmap they were
handing out yesterday at a Keio exhibition didn't have dates, but I
think 4G is generally targetted at 100Mbps. I will be surprised if it
takes more than a decade to become available here.
