ᐅ Is it necessary to have LAN cables installed in the garage?

Hello

I wanted to ask what the essential use for a LAN connection in the garage would be?

Our electrician is reluctant to install a Cat cable in the garage.

He is charging twice as much as for a Cat cable inside the house (€500 in the garage) just for a Cat socket.

Why do you absolutely need LAN in the garage?

Wallboxes usually all support Wi-Fi anyway.

We are also planning to install photovoltaic panels later on.

Ask the electrician what exactly he means by proper testing. So, he’s going to give you a test report according to DIN standards? You don’t really believe that.
They’re just messing with you. Sorry.
Ask him whether he installs empty conduits or not—in other words, making sure the cables can be replaced later. Find out what bending radii he uses, and so on.
He should simply pull in the cables for you (CAT7 over 1500 MHz) and you handle the patch panel and keystone terminations yourselves.
If he refuses, have the empty conduits installed and pull the cables yourself.
You’re building your house! You have to live with it. You’re spending a lot of money on it.
So do it your way and don’t knowingly create problems (that cost a lot more) just because one of the tradespeople isn’t willing to put in the effort.

Two more pages and we'll start crowdfunding to gather the 500€ for the duplex in the garage. At this point, the topic can hardly be taken seriously here anymore.

Sorry – I’m out of this tangent now. 😀

@Evolith Yes, we will now at least install Simplex wiring in the garage.

The only question left is whether to use Simplex or Duplex.

@rick2018 He is checking if the cable is properly connected and undamaged.
Yes, the Cat and Sat cables will be installed interchangeably in the conduit.
At least CAT7 will be used.

They do this check to avoid any disputes later if something stops working.

Unfortunately, as mentioned, conduit installation is not possible.

Yes, that’s the compromise you have to accept when building with a developer. (However, we found a house in a good location within our budget.)

What speaks against simply taking the drill after moving in and drilling through the partition wall? This is how it would be done in an existing building with the same floor plan. Afterwards, seal the hole. I wouldn’t pay 500€ for an outlet in the garage.

Ask him how exactly he "tests" it. Does he use a) a Fluke DSP or a comparable measurement device costing 5,000 to 10,000 Euros that can measure and record up to 1000 MHz, or b) a "10 Euro testing tool" that only checks the standard 1:1 wiring continuity?
If he chooses option (b), he might as well skip the test. That kind of device doesn’t check attenuation from crushing or bending, split pairs, etc.
And you won’t be sure if it will actually run 1 Gbit/s or 10 Gbit/s without interference during practical operation.

Can I ask at the next opportunity?

But it doesn’t really matter, he won’t lower his price for the patch panel.

He just offered us an alternative: instead of a patch panel, he suggests putting keystone jacks everywhere, so we can connect directly from the switch to the keystones. It’s a bit cheaper—10 ports for €250 (approx. $270).

For CAT Duplex cable, he gave us his internal pricing for the garage (as a courtesy): €220 (approx. $240) for duplex.

We will also have CAT Duplex installed in the garage.

Do we really need LAN in the bedroom? I can’t think of a use case right now.

The Wi-Fi access point will be installed on the same floor in the kids’ room.
