While others have suggested at least 10 ISPs would get into the action, I
still don't like unbundling. In my (narrow) mind, the local loop is
history. End of story. Its not just the cables (old construction, water in
it etc, but the terminations, dodgy splices, etc. But also that at best
xDSL will never deliver the sort of bandwidth that we as an industry want
to see in the as soon as possible future.

At last !! someone agrees with me.

No - we (NZ) just spent 10 years getting away from this.
The economics of local loop roll out are very simple and the figures apply
in both NZ and the US.
- You have to get into a house for under $1200 - thats the build, the kit,
connections, converters, etc (and often the set top box/router/whatever.
This is not too hard.
You have to take a total street or block approach not just one house. Then
you look at your uptake figures and as I mentioned before you do well if
you get 25 to 30%. I think Saturn got around 30% which internationally is
So you work out your street build and divide the number of houses and then
multiply by 4 and that is your return, so start applying your roi figures.

DON - they have been doing this for years ! remember that funny Palette
based mapping system I used to run at the MED ? technology now called
However getting trench co sharing is as hard as interconnect....... even
WCC find it hard agreeing to let us share a trench
However, its not that bad. Remember we are DEREGULATED. That means YOU can
dig up the road. Just fill in the form, comply with the specs and get out
your shovel. Hook up 12 people and get an operators licence. your own
letter from the GG.
But in fact its even easier. In large parts of the US the utility
reticulation is along the BACK fences. Thats where the poles are, not in
the street. So what you do is run your cables along the back fences using a
standard easement form for each home owner. They easy to train.
Now you start using NID boxes like we build. They're basically a fiber
media converter and an ethernet switch in a weatherproof box with psu and
surge protection. Simple traditional engineering. You put boxes every 100m
like good ethernet says, and you run cat-5 to the houses. If you can't do
it bloody cheap you go broke. If your're real clever you even skip the
fiber and just run gig copper between the boxes. THat saves you the media
converter costs which are the big hurdle. And since you are running copper
its about 30 cents per meter.
So why is a decent gigabit connection to a home so hard ?
Actually I only think we need 100mbps, but the gig switches are getting so
cheap might as well go for gig......
ps if you want to see real fun look at
http://www.r2.co.nz/20020219 its only wireless tho nothing too sexy, but it
does show the services like voice and video running.
