Dear Forum,
I have read several articles on this topic and gained some understanding, but it is still not entirely clear for our situation. I’m a complete beginner regarding this subject and now need to keep an eye on our interior contractor, who is handling everything for us (starting with the quote). Since I want to understand the services to be commissioned, I kindly ask for a plausible and, if possible, clearly explained answer with minimal technical jargon. Please excuse my perhaps very basic way of expressing myself!
Here is the background: we are building a single-family house with a ground floor, a finished attic, and an uninsulated loft on a concrete slab foundation. We want a satellite system with five connections (living room, 2 kids’ rooms, office, bedroom) as well as LAN wiring for the mentioned rooms.
First, about the LAN wiring: it was offered to install the LAN distribution panel and the router in the utility/technology room. From there, the individual rooms will presumably be wired. The offer includes cable installation, including connectors (which I understand as cabling), plus 5x BTR NETCOM outlet sockets, Cat. 7, 1x RJ45, Up0 TN E-DATmod-2Up0.
I have read a bit and understand that a network switch is needed to manage connections, but I don’t see it included in the offer. Will that be an additional cost? Are other components necessary?
Regarding Wi-Fi, will I be able to get coverage throughout the entire house (wood frame construction) from the technology room, or will I need a range extender? I have also read about access points; how do they work if I want Wi-Fi in both the living room and upstairs?
What about the telephone? No wall outlets were planned for it; it still needs to be installed somewhere. Will a normal cordless phone like a Gigaset TECT be enough, and do I only need a power outlet to connect it to the router? Or is more equipment required?
Concerning the satellite system, I was offered a 5-connection rooftop satellite system with a multiswitch, 85 cm dish / LNB / centrally located in the loft.
As an extra item, the preparation of satellite coax cables in the loft and grounding from the loft to the technology room is offered.
The price for the satellite system seems quite high. Therefore, I would prefer to have only the preparation done and then contract the remaining work separately. What do I need, or how should I arrange this? Should I have an empty conduit installed from the loft to the technology room? How is the cabling to the individual rooms done? Does it run from the technology room to the rooms or directly from the satellite dish in the loft?
Since LAN is already planned for the same rooms, is the satellite cable different (coaxial)?
Thank you very much in advance for your help and feedback. It’s incredible what challenges you have to deal with when building a house, which you never knew existed before.
Best regards,
Charly

You can also connect an outlet by hand without turning off the circuit breaker and without connecting the protective earth... It works, and in practice, you don’t notice any difference.
But it’s poor workmanship and remains poor workmanship.In fact, in this case you do notice a difference, since defective devices with leakage currents do occur.
And working under live voltage does happen as well...
However, this is not comparable to a LAN connection, where no safety-relevant aspects are neglected, only minimal measurable performance losses are possible.
I certainly would not recommend working live and leaving out the protective earth.

However, this is not comparable to the LAN connection, where no safety-critical aspects are ignored, but only minimal measurable performance losses may occur. I would definitely not recommend working live and omitting the protective earth (PE)...If just one of the eight wires isn’t properly connected, you can lose about 90% of the performance because the connection will first downgrade to 100 Mbps. That’s definitely more than “barely measurable.”

If even one of the eight wires isn’t properly connected, performance drops by about 90% right away, since the speed is then throttled down to 100 Mbps. That’s definitely more than just "barely noticeable."By “not properly connected,” you probably mean that there is no contact at all.
Apart from the fact that most people wouldn’t even notice this if they’re just browsing the internet, since their actual speeds are usually well below that, you’ve then introduced a general fault. The original question discussed whether it makes a difference if 2cm (1 inch) of aluminum foil shielding is missing in front of the contacts!
As I mentioned before, our company used to have a lab that conducted measurements on this topic.
The measurement results were basically all within the Gaussian normal distribution, regardless of whether 2cm (1 inch) of shielding was missing, whether the wires were laid exactly according to specifications, and whether a proper crimping tool was used or if the wire was carefully attached with a SMALL screwdriver.
The contacts are spring-loaded well enough to easily handle this, as long as you’re not constantly prying with a thick screwdriver.

readytorumble18 Mar 2017 19:27What happens if a conductor comes into contact with the ground in a LAN cable?
However, if the cable (from the technical room to the outlet), the outlet, and the labor cost $37, that’s really cheap.
The price of an outlet for your electrical system should be easy to find online nowadays...
The cost of CAT7 cable as well...
Just make sure the conductor cross-section is sufficient; some sellers advertise cables as Cat7 but the conductors are barely thicker than a hair (exaggerated).[/QUOTE]
It’s true that you can find a lot of information online, but as a layperson, it’s hard to judge which of the many offers you actually need...
You’re right, $37 for everything would indeed be cheap, but that was only for the outlet. The cable installation and termination were additional charges.
So it will definitely be Cat7 cable, but Cat6 outlets can also be used if I’m correctly informed. Right?
