Which type of conduit to place in wet concrete?

[Andy Hall]

There's a solution to the corrugated conduit problem.

- Take small piece of cloth and tie a stout linen thread to it. Thread is a little longer than conduit

- Tie a piece of string to the thread. String is just over twice length of conduit

- Tie cable to string at the middle. Tape it carefully to prevent cable end snagging in the conduit.

- Tape a small piece of nylon stocking or eqivalent to one end of conduit.

- Place vacuum cleaner nozzle over same end and tape over to make a seal. Use duct tape - it's good enough for Tom Hanks and space rockets so will be fine for this.

- Turn on vacuum cleaner and introduce cloth carefully into open end of conduit. If it tends to stick, cut off some cloth.

- Introduce thread in slowly until it stops (length will show that it's add the far end.

- Turn off vacuum cleaner and remove nozzle and piece of nylon.

- Pull through thread, followed by string and cable.

- This will leave cable and a piece of string in the conduit for pulling through in the future.

Use 25mm conduit or preferably the larger 50mm stuff that's used under footpaths etc.

The draft specs and manufacturers' marketing departments mention this speed. It is only achievable under ideal conditions over a short range.

Data transfers of large files?

In that case, I would turn on some form of security....

[Andy Hall]

Actually he does.

Considerably more than you, I suspect.

[Andy Hall]

You don't, you know.....

yah. ok. whatever.

[Geronimo W. Christ Esq]

It depends on the environment, but in an home/office LAN very seldom. I can't imagine why someone would have a LAN at home and spend time constantly copying files up and down. Nightly backups are just about the only practical example that I can think of ...

Why on earth would I do that ?

[Steve Walker]

Your graceful apology & retraction is accepted.

[Andy Hall]

It depends on what the business is that they carry out on their home office.

If it is related to IT/networking or to some form of media handling then the data volumes can be large.

There are many more.

Up to you.

One philosophy is not to bother with security in the wireless domain, to treat the wireless network as dirty and connect to the protected network via a firewall.

A second one is to use one of the wireless security mechanisms

A third is to use both of the above.

A fourth (for the terminally stupid, and what tends to come out of the box) is to do neither.

Real throughput? or a marketing, ideal conditions, never to be seen in the real world, headline rate?

WiFi or some other technology? I was careful to specify WiFi as I am aware of systems that will run at pretty fast speeds but they tend to be point to point and cost several grand or more at each end.

So I don't have to wait for the data to trickle to/from the server and my machine. One single A4 photo print this morning was 56.5Meg is size. Approx 45 seconds at 10Mbps or 4.5 seconds at 100Mbps, I know which I prefer...

Oh dear. With any radio based system anyone within radio range can "see" the traffic on that system. This applies not only to WiFi but baby alarms, cordless phones, anything that uses a radio. How much of a security hole this is depends on the technology used and what security features are included *and* enabled.

At the bottom end I believe that baby alarms can be "interesting" when the parents of said baby think that having a second baby would be nice. B-)

You just made the physical connections and nothing else? You didn't have to load a driver or configure anything? Oh dear, yet another wireless LAN available for free loaders and identity thieves. Down in the town the majority of the domestic wireless LANs that have sprung up in the last year or so are wide open. Default ID's, default passwords, no encryption etc etc.

[Dave Liquorice]

I got a draw line in (steel draw tape) but not matter how hard I pulled the CAT5 wouldn't come through unless the 20mm conduit was almost 100% straight.

B-) Apollo 13, must watch that again some time. Remember it from real time as well.

[meow2222]

It wont, but conduit does give the advantage that you can run anything else down there if you ever want to in future.

BT Router impressed me the other day, out of the box with WPA enabled.Well done BT.

Some issues with capacitance to ground, and some with chemical action.

I'd use preloaded flexible round trunking, or even a bit of flexible heating pipe that is designed for UFH.

[The Natural Philosopher]

Are there any wifi systems that will punch through walls rendered over steel mesh?

oh, that's me crushed.

[Andy Hall]

Did they remember to include the password?

Is it the same for all of them or based on something like the MAC address, or is it genuinely individual and random?

[Andy Hall]

Some towns take a lot of civic pride in having that, although not normally through the incompetence of individuals.

Bury St. Edmunds who have internet access built into a park bench for example

[Rick Hughes]

You do not need crush resistant, rust proof or similar ... it's going to be incased in concrete so has all strength it needs from that.

[gort]

Yes, its on the bottom of the router on a label. No idea, I would like to think its random, but this is BT!
