I'm planning to cable network my house whilst building an extension. I want to minimise later requirement for rewiring (and cost). I work from home but am a baby boomer, so don't know for how much longer. I'm not in town, so internet is satellite and I think fibre optic is only dream for phone. I want the network to connect (usually 4) computers, peripherals and carry my video signals for watching and recording TV. I've been planning on Cat 6 with a comms rack with patch panel and ethernet switch. I plan to have at least 2 RJ45 sockets in each room so that I can use one set for phone signals but change use of individual sockets as needs vary. I'm not planning on buying phone system, just plug single line phone to socket carrying the specific line required. My latest request for a quote provided me with advice not to use Cat 6 as high frequency cable gives poor performance with phone signals and can damage components, specifically switches. Can anyone comment on my plans and the accuracy of this advice?
I would get a quote from someone else. They probably cannot get any Cat6 cable at a decent price and so are trying to get you to go for cheaper cable. Or they're just, you know, not the company you want to go with.

There is another question, what speeds can your ISP deliver in your area? If you only can get a ADSL with a theoretical speed at 24Mbit/s it is really overkill to have a 10Gbit/s LAN. If you don't need this speed locally?
I would say that you still get most worth for your money with the old Cat5 cables, and then use them to run 1GBit/s Ethernet.
And since those Cat5 cables are cheep, pull 2 cables in the wall one for Ethernet and one for phone.
But to answer your question, the Cat6 is more expensive a has a little bit better quality but more or less does the same as the Cat5. And there is no problem using Cat6 for both phone and Ethernet (not at the same time thou...)

A local question: Cat5 vs Cat5e vs Cat6 cable confusion,
My short opinion, if you are not planning on a 10G local Ethernet at home some time soon, take the
I will once again request that you check your bandwidth requirements at home :-). You can probably run more than 10 Full-HD streams at 1Gbps. What do you intend to do with a 10Gbps LAN in the next 5 years? (this is likely to be taken down like many last words, yet I'd like to know if anyone here has points against this statement today).
Seriously, unless you are also going to invest in other elements of a super-fast network, I would imagine the additional cost will be for no noticeable benefit.
CAT6 is not just about the cable, it is also about the other components (faceplates, patch panel etc), and the way they are instaled (CAT6 is only Gigabit rated if installed properly, for example the minimum bend radius is much larger than for CAT5e at 100Mbps when going round corners inside walls).
I can't see how using the twisted pair cable as a phone extension will have any effect on other devices such as switches that are nothing to do with them. I don't know if these low-tech devices do or don't perform less well on cable optimised for higher freqency use.
