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

http://rdvlivefromtokyo.blogspot.com/2005/11/mom-your-teapot-emailed-

me-and.html

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.
