instead of having to dig up roads etc, why can't nz ISP's run fibre optic through the sewer system like Paris does. It says in this story from Xtramsn:

And regarding wi-fi access. If there was a 54Mbps access point, and 2 users were using it at the same time would each user get 27Mbps(half of 54Mbps) each?

It's quite simple. New Zealand is a small country, with only a short period of "European" "civilisation. The services in old cities were built over many centuries.

The sewers in Paris, and quite a few other old large cities, aren't concrete pipes like those used here. They are underground rivers, in large tunnels, with walkways, roads, and railways. There are tours (savvytraveler.publicradio.org/show/features/2000/20000311/sewers.shtml). It would be easy to put plastic hoses along them to carry fibre optic cables.

It's not a realistic proposition to run tours (or fibre optic) in a 600 mm concrete sewer pipe.

It would be nice, BUT I doubt it.This would only apply on a network, not 27 or 54mb on the internet.

It'll be even slower if you're on dialup, if one person is downloading if you're on a wireless network. The same as if you were on a ethernet network.

It's a shame really I'd like to see the Xtraordinaries working in the sewers :D

In some places people have been smart enough to buy the rights to reuse old gas pipes for running fibre.

I think its a great idea, imagine your broadband cable winding out of the loo like a snake.

I would hate to be the installer though .....

My internets running like 5hit tonight :lol:

If there was a 54Mbps access point, and 2 users were using it at the same time would each user get 27Mbps(half of 54Mbps) each?No every one will get 54Mb connection for the local network and 2-3.5Mb connection for the net(broard band), the throughput is a different matter, unless someone is streaming something across the network every one should have full network speed.
