Somehow 1000's of phones are able to speak to a tower miles away, but you are telling me my phone can't load youtube through my fat husband when lies down to sleep
This has to do with the radio frequency being used. A higher frequency can carry more data but has a harder time penetrating objects.
Most cell phone use frequencies below 1GHz. Years ago a consumer wifi company released a router combo that I thinkc could do 10 Gigabits per second, over 10 times our current normal speed. But they used a frequency above 60GHz and simply holding a piece of paper directly between the computer and router line of sight caused the connection to drop.
