Not all families hotspot of one mobiles or only have one mobile for the whole family. Most families I know each family member (over 8-10 years old) has their own. The family outlined below each have their own smartphones but wifi when at home.
I was indicating the one set of eyes on the one person.
We have a close friend which has a family like the Brady bunch…two teenage kid aged families merged. They have up to 4 teenagers at any one time + two (step) parents.
They moved house to one that had fibre and took out a top tier NBN package as they had HFC at the previous house which caused a lot of problems (they all wanted to grab their own bandwidth which wasn’t possible).
Even with the top tier NBN, they were still having problems particularly with their home WIFI capacity causing significant lag/buffering problems when watching videos/intensive online gaming (4 kids on their devices and parents either sharing one or on their own).
My mate decided to see the setting on the video streaming apps and all were running at maximum resolution even though such wasn’t needed for hand held devices. Changing a few setting and re-educating (inc. turning off streaming when not in use) the kids paid dividends as the streaming is now more stable.
I understand that arguments still occur when the microwave goes on when signal inference occurs.
I have mentioned what happened to the ‘good old days’ when the family plonked itself down in front of the TV (show or movie) and enjoyed it together). In some families it seems that individualism has taken over familism.
Maybe we are old fashioned in our household, but we subscribe to familism.
