Errrrrr - but will anyone be using cable (rather than wireless) in a few

why not go wireless now? It's cheap, easy and far more flexible!

It depends on what is required.

Wireless networks are certainly very useful in a number of
applications, but there are limitations.

- Taking gross (rather than real) bandwidths, wireless networks are in
the 10 - 50Mbit range while wired is in the 100-1000 Mbit range
currently.

- The current wireless technology produces a shared network, so the
bandwidth is shared among all users. A cabled network can be switched
and achieve higher performance. This effect can be ameliorated
somewhat by increasing the density of access points and connecting
them to switches but this increases the cost of course.

- There are security issues with WiFi that may be at an acceptable
level for a home user but are not for business purposes without the
use of additional encryption and other security techniques.


So, yes, I think that people will be using wired networks and adding
wireless for a long time to come.

No, it's not intuitive. Reasons are buried in the mists of old-style

badness of separating pairs too far to carry on the "next outermost
pair" pattern when you get to bigget RJ45 plugs. (No BellSystem
pedants about Proper Names for RJ11/RJ45, please!).

Once you accept - as you really must - this need for keeping the
pairs in order, you may as well go the whole hog and stick to exactly
one of the two accepted schemes: from memory, it's blue pair for 1/2,
brown pair for 7/8, and then a matter of religion (-A or -B) as to
whether your green pair goes 4/5 and the orange 3/6, or t'other way
round. *Functionally*, provided you pair consistently, the colours
you use, and which way round you do solid vs stripe, doesn't matter
at all: electrons are colour-blind. But failing to stick to exactly
one of the two standard wiring schemes is pretty well guaranteed to

This page shows the two T568 variants, and the point about T568-B
being more common in equipment that you buy such as patch panels seems
to be the case.

But the pairs are physicaly located in a different place in the cable.
I suspect this could make a difference when really pushing the abilty
of the cable to carry the signal without to much degredation.

later
Checked the construction of a bit of CAT5, the pairs are arranged:

org
grn blu
brn

The wiring is:

T568A T568B
grn 1/2 org 1/2
org 3/6 grn 3/6
blu 4/5 blu 4/5
brn 7/8 brn 7/8

As can be seen the change in the org/grn wiring is not symetrical in
the cable, so a signal on the org pair is now physically closer to the
brn pair, like wise more separation greater for the grn/brn.

Now ethernet (10/100Mbps, not sure about Gigabit) only uses two pairs
the other two are not connected so it's probably not an issue with
ethernet but could be with other uses of CAT5.

Yes. Wireless is insecure, and somewhat more expensive, and somewhat
more prone to problems with metal in the walls etc.

Its also more limited on bandwidth.

If everybody used gigabit wirelss to connect up their home networks,
there would be horrendous problems with adjacent properties

No problem tho with wire or fiber.

Not necessarily.With current technology maybe that's true, but I
imagine in the years ahead the wireless options will expand and the
wireless devices will be hugely more configurable.

Model aircraft don't have a problem flying together, unless some divot
happens to choose the same frequency as someone else.

Don't be dumb. Bitrates on model aircfat are at best 2400 baud, and
limited to about 30 channels on the band. Channels are 10Khz apart, so
useable BW is les than 5Khz. You won't get 100Mbps on that.

The ONLY way to get higher BW on radio is to use ever higher frequencies
- cellphonse use 900Mhz or 1.8Ghz, WiFi is 2.4Ghz, and even then, its
gettng crowded.

Waveguides - be they wire, hollow pipes, or glass fibres, allow the use
of the same carriers and the full broadband spectrum without
interference. They will ALWAYS be able to carry more signal with less
interference than an equivalent broadcast system at similar bandwidth.


You can get at least 8 GBPS down a fiber. The best of microwave
technology using large aerials and big towers and highly directional
links, is a few hundred Mbps at best.

Wifi as currently constituted is a shared space collison detectieon
'Ethernet' of typically 10Mbps, up to maybe 50Mbps. Any piece of cat 5
will do 100Mbps short range and no collision problems at all if a switch
is used and there is no coincidence of traffic between nodes.


You only hgave to listen to e.g. a cellphone qality versus a decent
analog or digital phone over landlines, to hear the difference between a
clear unobstructed 64Kbps channel and a highly contended bandwidth
limiteed compressed to the nth degree and frequency spread system.

Bandwidth is always tight with radio. There is never enough space to do
what you want. Sometmes its a cheap way to elimninate wires or fibers,
but its never ever the BEST way for a duplex system. Broadcast? yes. It
works well for TV and radio, it basically sucks with bi-directional data.

It is however, a very cheap way to work if limited performance is
acceptable, and the cost of laying lines is exceptionally high, which is
why half of the long haul data in this country goes via microwaves.
However, these are getting congested already, and fiber is the answer -
it just costs a ****load of money - mostly in terms of obtaining
permission - to lay it.

If you have a chance to rewire, lay in cables, or better still, fiber.

I wnxer why we still have TV downleads. Surely we should be able to do
it by wireless links :-) In fact, I wonder whay we still use any cables
at all. :-) :-)

Cos they work BETTER than most other things at delivering a clean signal
through and unpredictable environment.

You can get a whole lot more than that in one fibre! 100x 2.5Gbps channels
(wavelength division multiplexing). Way over the top for home use. 10Gbps
is probably more in the DIYer's range.

As explained in another post, there's always more effective capacity
for shifting signals around if you actively guide them (through cable)
than if you radiate them through free space (even if you try to do it
directionally). There'll always be an economic tradeoff between fixed
wiring (higher up-front cost, larger ultimate capacity, cheaper
interfaces, longer-lasting infrastructure) and wireless stuff (less
up-front cost, incremental cost greater, data rate limited to whatever
you buy first time round). It's naive to suggest that fixed copper/fibre
is going away any time soon. For home use, many may find wireless more
convenient; but it's kinda self-limiting, as more and more devices
crowd into that little bit of "no-license-needed" spectrum around
2.4GHz.

Baluns, for feeding the 300MHz baseband video signal over twsited-pair.
Canford Audio will happily add to your debt burden at about 80 quid a
pop (you need a pair, so that's 160 quid; probably plus VAT). Canford Cat
not to hand, so price is ballpark from memory. In the spirit of uk.d-i-y,
someone (Mr Liquorice, mayhap) may soon be along to tell you exactly
which pair of transformer-looking-affairs from the guts of a 45-quid Asda

Not me squire. I can't see why a video recorder would need video
baluns to start with. However on Canford...

They have a range available:

2 x audio =A376.94
4 x audio =A3117.50
1 x video =A336.63
3 x video =A3108.30
1 x video, 2 x audio =A377.85
2 x video, 2 x audio =A392.24
1 x S video, 2 x audio =A3130.70

All above sold as single units, two required to complete a link.

1 x VGA to 1 monitor =A3252.00
1 x VGA to 2 monitors =A3396.20

As a set of send and receive units, inc PSU for the 2 monitor version.

Distances & Bandwidth:

Audio: 750m (10Hz to 20kHz)
Video, composite: 675m (DC to 60MHz)
Video, Y/C: 600m (Flat to 60MHz)
Video, RGB: 150m (Flat to 60MHz)
Video, VGA: 105m (Flat to 60MHz)

In the 50's they all said internal combustion engine would be extinct and we

If you are building a new house it makes total sense to flood wire with
CAT5, it is peanuts in price compared to building costs - and so what if in
the future you don't use it.

But it is a hell of a pain if you want it and didn't put in in during build
time.


I have built a new place and put in several km's of CAT5 and also more than
a km of CT100.

I put multiple rums of each to every room, extra CAT5 to ceiling sensor
locations, alarm detectors, inside & out, possible projector locations etc.

I imagine your home must be lit up like a christmas tree to a passing

Seriously though, if a lightning strike came to earth somewhere close
to your home I would expect all that extra wiring to act as a
conductive path to possibly take out the whole house. Have you taken
any precautions about that possibility?

Also, could you not use fibre optic, which doesn't have the lightning

for future transmission speeds.
