Are LAN sockets still up-to-date? WLAN/wireless is the future!

. Is DECT still an option?? Does it work if the router is in the basement and there are reinforced concrete ceilings in between?
I'm sure my questions sound amateurish.... but I'm an amateur in this field.

I have Fritzboxes as access points, they do WLAN and DECT, and the phones are connected to the Fritzbox. You could keep an eye out for a set consisting of a 7590 and 1750e. Then you have one access point and one Fritzbox as an access point with DECT. The two can also mesh.

At MM, for example, there is currently a set with the 7590 + 1750 + FRITZ!Fon C4 for 269.99.

Alternatively, set a notification on my dealz, the set without the phone is occasionally offered for 180€.

Cisco manufactures, in my opinion, affordable IP phones with Ethernet connection instead of TAE. However, these are office devices with cables. Affordable means under 50,- per piece. You then plug it in where there is a network socket.

Now I am a lot wiser again. Very nice. Thanks.
At first, I would rather not use the Fritzboxes as access points for aesthetic reasons. I have already gotten used to using Ubiquiti UniFi as access points.
FritzBox or a similar router that already supports DECT goes into the basement, hoping that the signal reaches the upper floor. But since the second access point is supposed to go into the attic, which is not visible anyway, another Fritzbox might be an idea here. The important thing is to pull the appropriate cables to the right place first.
However, I am facing the usual problem you have when you have no idea and are building with a general contractor. "TELEFONANSCHLÜSSE" were offered in every room. Of course, I do not need that as I have learned. Now I have to wait for the surcharge for the required network cables. I have to discuss that with the electrician. But if he already makes the slots for the telephone connections according to the delivery scope, he can also install the corresponding conduits to keep the whole thing somewhat cost-neutral. I will take care of the rest.

We have installed a double socket under the window in every room. A desk will be placed somewhere nearby, and the rest will be connected with cables. The children's rooms are obviously still unused. The little ones are still too small. The living room has 4 sockets. One for TV, one for PlayStation, one for satellite receiver, and one still free. On the other side of the wall there are 3 more sockets. One for printer, one for mower robot gateway, one for docking station (home office). In the garage there is also a socket ... the Xbox of my husband is connected there. In the bedroom, the second TV is connected to the socket. The children's rooms will later be supplied with TV and console/PC via LAN. So, in the future, all sockets will be occupied in our house. Of course, we did not put a socket in every corner. That's why God put cables in the world. I remember my youth. My parents were building. Every room had a LAN connection, but my father was too stingy (for whatever reason) to have all the cables connected. So we all used Wi-Fi. Thanks to thick concrete ceiling, the reception was mediocre. One access point kept messing up and losing connection. Don't ask me why. We all got frustrated because everyone was moving at snail's pace. That was 15 years ago. Currently, Wi-Fi can do a lot. But games, movies, and websites are becoming increasingly resource-intensive. On top of that comes the security aspect and connection stability.

When I read that, I had to smile a bit. Because when I remember, it occurs to me how I sat with Grandpa on New Year’s and watched ski jumping in Garmisch with him in black and white. At Grandpa’s, because my parents didn’t even have a TV yet due to lack of money. - And I learn that today husbands have Xboxes in the garage. I actually associate those devices in my imagination with teenagers. - Well, panta rei, as they said in antiquity.
