CAT5 (And CAT6 etc etc) Installation
Discussion
I've got a business idea that i'm looking to develop over the coming months ready for when I finish uni in June.
Do you have to be accredited to install CAT5/CAT6 cabling?
Are there any courses you can go on?
May sound like a strange question but just something that has been niggling at me!
Thanks,
Phill

As has been said, there are general training courses, but mosdt large manufacturers offer their own training courses and at the end of which you can install the product the they will warentee it (spelling)
However the commercial market is dead, lots of people bidding on little work.
The alternative.
Install in houses! SOunds odd but this market is going to be the big one for the next couple of years. Which (funnily enough) is exactly the market we can help you target

Do you think wireless will impact much on the home wired solution? I know I installed cabling in my house as I did it up but that was just because it was free *cough*, but must admit that now I rely on wireless, which funnily enough was also free *cough*
Obviously, there's more services that can easily be run over copper, but I'd be interested to knowhow much of a boom market you think it will be (don't worry, trying to get out of computing, not branching off).
Must admit, wish I'd run a vacumn system in with the wires now!

popey,
Is hate wireless, not because it is a rival, but because it is not everything it is cracked up to be.
We have it at home and after two walls, a ceiling and my back to the router it is intermitant. They don't tell you that when you buy it.
Also, as a RF Engineer the houses we build are using metal uprights for stud work and foil backed plasterboard more and more. This causes a nightmare for wireless signals and will create an effect call a faraday cage, which prevents signals getting in or out!
Other issues that the general masses are less aware of is securtiy and bandwidth. The number of domestic wifi connection I can use is scary and the as more people use the service the speed drops! OK for internet use with its sporadic bursts of page requests and downloads put useless for anything that streams data for instant use, such as VOIP and Video as they need a good constant feed.
(if you really what to know about it I wrote a paper about noise on cable tv data services that explains this a bit more)
The way I see it going is a hybrid solution.
There is a place for wireless, but I see it becoming a lot like zigbee or bluetooth, wired to a room and then wireless within the room so that you can still roam without cables.

Snap, I have to look after 80 (and counting) AP's on campus!

Ah, much easier if you're new building to install wiring, and infinitely more sensible. The amount of times I have to retrieve a basestation from a data cabinet as the user thinks it's a good secure place to put it. Well, it is as no one will be able to tell there's an AP in the area to nick!

It's scary how little people realise the woeful level of security on wireless. Unfortunately we actually had our Uni's Registrar think it was Gods gift and wanted to replace all the copper with wireless, as it was cheaper.......

Indeed, totally agree. Unfortunately, you can't really compete with the mass marketing of things such as 'Intel Centrino Mobile Technology' (ding ding ding) as it's spoon fed to people as a marvellous solution without the warnings. Interesting, I was driving through Belgium over New Year and they have hot spots in most of their motorway services (Cisco boxes). Picked up a leaflet and the first instruction was to turn off any encryption.......
Apologies Phil, seem to have hijacked and gone a bit off topic.
To commercially install data networks you must be able to certify the installation to perform to a specific standard.
In a residential setting this isnt strictly neccesary but a good idea.
The certification process is done via a network tester which tests that the install has been done according to the wire standards and that the wire is capable of carrying the amount of data that it is designed to.
If you want to mail me Phil, I install residential networks and the lighting control, automation, security, HVAC etc that hangs off it for a living and would be happy to answer any questions.
With regards to the sub-question about wireless networks, they will make an impact and fairly soon, the technology isnt quite there yet though. The simple rule is that if you can run wire, you always should.

Looking at the price of microcontrollers that support basic wireless communication now I'd be surprised if these didn't become standard components in the house within the next 10 or 20 years for pretty much everything ... controlling the central heating, burglar alarm and its sensors, lights, entertainment systems, etc, etc. Some of these devices already provide a mesh where each device can be used as a stepping stone to get data from one end of the system to the other in hops (meaning broadcasting range of any single device is much less of an issue). Using these devices simplifies the initial wiring requirement in a house, and makes moving switches, thermostats, motion detectors, etc much easier, plus it lets you control the devices in your house in an entirely new (and possibly even useful) way. At the moment there is still a fairly limited market for these devices, but if that market grows, the price of these devices will fall, which in turn will increase the market, etc, etc. In bulk you can currently get them for about £40 each. If that fell to £4, imagine what you could do.
Cabling will always provide a higher bandwidth and more physically secure channel, but it is inflexible. It makes sense to use it for any data backbone that really needs high bandwidth, but most devices don't need more than a high quality video link and current wireless supports that quite well. Frinstance, I use cheap laptops with very high res screens to run terminal services on a powerful server because I'm working with files that are tens of GBs in size. They take ages to move btwn machines even over Gb wired connections so it makes much better sense to use a terminal/server model and just use the cheapo laptop for its screen and keyboard and portability.

This is where the mix will work. Buy a Centrino pc (as i have) and run wires to a central point for each room, then plug in a simple wifi device to beam it into the room. Easy to do, just need a manufacturer to make a wifi device that looks like a ceiling speaker (now there is an idea!)

Ditto, sorry Phil.
SSShhhhh.
I am working on it.
I have prices for plug in dimmers and swtiche (X-10 type) devices and there is availabilty, I am waiting for some other bits before we commit.
Sorry to continue with the Hijack Phil.
I am going to start another thread fo this.

Really?
I've got a job on at the moment for 10 Z Wave controls plus the remote and a modem.
I've been on to the crowd near me (retail) and a chap in the states, if you can get supply at trade then obviously...
ATG said:
ATG,
The control element is already avaiable with ZWave and Zigbee. It does all the meshing etc and just needs manufacturers to adopt it and way we go. It will be great for retro fit markets.
Broadly comparable with the X10 pricing scheme, a little more but nothing outrageous.
Disagree slightly on the subject of wireless....
Security is fine if you use WPA etc, it's just that most people don't implement it properly.
As far as signalls / bandwidth etc, wireless is not going to replace cables in a corporate environment for some time to come, but domestic and outdoor wireless networks are now good enough for most situations, and where there is a problem a hybrid solution can be implemented.
All imho of course

Agree completely and exactly as you said, how many people actualy turn it on in their home systems?
I leached of a Wifi connection here until my ADSL was connected, worked perfectly for a week or so!
