LAN, WLAN, bandwidths and contents?

On the topic of WiFi: Then your kids must never grow older. Let's say Mom, Dad, and 2 kids. Mom watches her soap opera on the TV via streaming, Dad browses the internet (including YouTube) for instructions to repair the darn washing machine. Junior, just proudly turned 16, plays online on the Playstation with his friends, while simultaneously running a group voice chat on his phone. The little daughter, all of 12 years old, watches what YouTube and Instagram have to offer. All, of course, in HD. Her friend hangs out next to her with her phone and eagerly joins in. Show me the Wi-Fi channel that wouldn't collapse under this. Exactly for such cases you need one or the other LAN cable. Console and TV can reduce bandwidth usage by using cables, thus freeing up some air to properly supply the mobile devices with enough speed. If, like for example Nordlys, you usually have peace from the youth most of the time, WiFi is basically sufficient. But with offspring, it becomes a tricky situation and it won't be long before the little ones blame each other for disconnecting from the network.

And so that the kids can ruin their brains with such crap, the modern helicopter mom lets the up-to-date Koptervati deploy 200 Landosen.....you’re crazy. The 12-year-old is supposed to go outside into real life with her friend, and the boy as well.

24/7?

There should also be something like online leisure activities... and the sensible guardian does not forbid this, but limits the time available for it so that the kids learn to independently manage a time budget for themselves. And if they find it boring after using up their time, they will go outside on their own.

Anyway, I wouldn't care whether they are on the WLAN with four devices at the same time or not. Then it just lags if they don't find a middle ground.

Only it also lags with you.

And no, I am not going to do the devil’s work and forbid my children from having a console or later a smartphone. That would be just as stupid as when I was forbidden the Gameboy and the Barbie doll back then. It also has nothing to do with [Helimama] or 200 LAN sockets. Just as Chand wrote. A ban on the toys that children are currently using is not purposeful at all. Rather, the educational limiting, when it becomes necessary.
My uncle grumbled at the last family gathering because our little one is so confident on the phone. The poor boy is supposedly wasting away. That he had been romping outside for 4 hours before, he conveniently overlooked. That he was watching [die Sendung mit der Maus] on the phone, in which a car engine was being explained at that moment, as well.
He just as gladly rants about the Lego toys. The junk keeps the child inside and prevents him from playing outside in the mud (my son hates getting muddy with his hands, he doesn’t even willingly knead cake dough). I could explain ten times that he plays outside all day in daycare and is then happy in the evening to be able to craft alone in a room.

Just the image quality over satellite is no longer up to date. Today, devices with an average size of over 50" are sold. Ideally, you want to watch in 4K, of course. And that is available on Netflix and Co., but as far as I know not via satellite.

Yes and no.

Yes, most 4K media currently come via the internet.
No, most "normal" streams are worse (because more heavily compressed) than the satellite signal of the same resolution. And also about one minute delayed.

By the way, if you only look at the resolution, the small HD resolution (720p) would be completely sufficient up to 50-60 inches. ARD and ZDF set a good example.
From about 2 meters screen diagonal with a projector, Full HD then makes sense.
No one needs 4K for film and television at home (even in the future). Even in cinemas, 2K is the limit. Currently, 95% of all films are already kept at 2K in production.

At home, rather the color depth (keyword HDR) and a gentle compression of the material make sense.
