LAN / SAT wiring in single-family house

So Cat7 cables will definitely be used, and Cat6 outlets will work for that if I am correctly informed. Right?

Yes, CAT 7 works, outlets for CAT 7 are still rare, so CAT 6 or CAT 6a outlets.

Since CAT 7 cables are not significantly more expensive than CAT 6a cables, buying them is worthwhile and you can upgrade the outlets later. However, you will only have the CAT 6a or CAT 6 speed, which must definitely be verified afterwards by a category measurement.

CAT 6(A) and CAT 7 have the same speed, the difference is the maximum cable length. And these are lengths that hardly anyone would reach in a single-family house. The difference starts from CAT 8, but I personally consider 40 Gigabit to be quite exaggerated, although some may surely see it differently.

So for surfing the internet or streaming a movie or music in the house, that is the minimum you "have to" have...

Sure, you need a backbone like a medium-sized company...

With some, one could really get the impression that nothing works without a programmable 48-port Cisco switch...
