Wiring for AP, choosing the correct network cable

Can someone maybe still explain to me how the power via PoE is transmitted through the cable to the access point, or which device supplies the cables with power?

I would also be interested! But also what the 3 additional connections will approximately cost you?

The connections themselves are not expensive, 35€ net per connection. In the end, it is the total sum that matters... you just have to see what you need and what you don’t. For us, it quickly turned into 5000 euros in extra requests...

Wow, bargain :D Provided that the cable, [Dose] and [Patchfeld] each include installation.

35 EUR?! o_O Either the electrician can't do math, or he's only charging for the cable - or something is wrong. For 35 EUR you can't even realize such a connection with bell wire, and no one has installed or tested the material yet.

You are right. I got the sockets mixed up. The price is €69 net. Sorry for the confusion.

also still a very fair price. Now he (the electrician) just has to do it properly ;)
