Network installation depends on location, requirements, and preferences. Bandwidth (or speed) is usually needed for many data-intensive parallel applications. We don't have that and have no plans for it. Our guys are constantly online, gaming and streaming a lot. Instead of countless LAN sockets, they get their own internet connection, because that is the bottleneck. In the new house, we receive three weak WLAN signals from neighbors. Interferences like in dense settlements are not to be expected. For us serial users, most things then work flawlessly over WLAN. We have consciously decided against "smart" applications, as we are currently experiencing how simple dimmer switches become a challenge for people slowly sinking into dementia. We want to understand our environment as long as possible in its basic functions and, for example, be able to turn on the light. Try that at an old age with a KNX switch, of which 6 pieces are crowded in a small space.
