ᐅ How can I set up Wi-Fi and telephone services, as well as technical installations, in the basement?

Hello everyone,

Since I am a complete beginner in the IT field, I’m asking for your help.

We are currently building a semi-detached house. Because of the underfloor heating, I have planned a CAT7 connection on every floor.

Now I’m wondering how I can later provide Wi-Fi and telephony throughout the house.

The incoming service line is located in the basement.

How can I distribute the telephony and Wi-Fi in the house using a FritzBox? I was thinking of installing an access point at the CAT7 outlets on every floor where needed. But how do I get the LAN connection there? Is it enough to connect the FritzBox in the basement to the network ports that end at the CAT7 outlets and then set up access points?

Also, I need to know how to connect a telephone (which will be located on the ground floor) to the FritzBox that is in the basement. Maybe Wi-Fi telephony?

Sorry for my awkwardness and many thanks for your help!

Phew, with ThermoMix it’s naturally going to be tight.

Jokes aside. Yes, that’s more than enough. You’re not even close to fully utilizing cat7. If you’re using a Fritzbox, you should also use the matching Fritzbox repeater/access point (for example, FritzRepeater 2400), because then you’ll broadcast just one Wi-Fi network for the entire house and prevent devices from switching back and forth between different Wi-Fi networks.

No repeaters. If using Fritz APs, operate them as true access points connected by cable.

How many floors do you have? I only read about a basement and a ground floor.

I would first try using just one Fritzbox in the basement for the phones. The signal penetrates walls and ceilings better than Wi-Fi, so that might already be enough to make calls throughout the house. For Wi-Fi, of course, one access point per floor is recommended.

If your network requirements are very basic, the Fritzbox on the ground floor without additional access points might also be sufficient. As with the phones, just try it out. You can always rearrange and expand everything in the basement later.

Cat 6a is fully sufficient. Cat 7 outlets would be a bit excessive.
The current standard for data up to 1000 Mbps is Cat5e (100 MHz).

I would just give it a try. We always install duplex cables, so one port can be used as a line for DSL/fiber, while the other port can supply a switch in the distribution panel. The phone can be connected either via the A/B port or DECT to the Fritzbox.
Then you can test how far you get.
I use a 7590 as a router and a 7490 as a router. One is enough for the entire house.

When is the move-in planned? I would recommend postponing the selection of devices as long as possible since Wi-Fi is currently transitioning to Wi-Fi 6. Because you rely heavily on Wi-Fi, I would try to choose Wi-Fi 6 equipment. It is important to stick to one manufacturer and possibly even one product series. Since you mentioned the FritzBox, it’s best to go with everything from AVM. The 75xx AX series was briefly announced, but AVM backed off after the virtual IFA event. I think AVM now wants to focus on introducing the new FritzOS on their current devices first.

Whether Wi-Fi will be sufficient for you depends on your requirements. Stable Wi-Fi is generally slower, and faster Wi-Fi tends to be less stable. Additionally, there are other factors influencing Wi-Fi performance. One factor can be neighboring Wi-Fi networks. This is usually not a big problem in a detached house, but it can be challenging in semi-detached or multi-family houses. Another point to consider is the building structure. How many walls does the signal have to pass through, and what materials were used? Your Wi-Fi device (router or access point) should be placed as high and unobstructed as possible. Avoid putting the device inside a cabinet, on the floor, or right next to other electrical appliances.

Sorry to jump in here briefly, but I need to ask a quick question.

My plan was actually to combine a Fritzbox as a modem with Unifi Lite access point(s), and use Fritz for phone as well.
Will I have issues because of the different manufacturers?
