When inside a large group of people (at a stadium, concert, festival), why does your phones internet data stop working despite having full bars? Why does such a large presence of phones in one area limit every phones’ usability and ability to even simply send a text message?
In: Technology
Think of your phone as a person yelling everything so loudly that it can be heard miles away. It says everything just right, and the person listening miles away (the cell phone tower) has very good hearing, so usually it works very well.
But, if a thousand people are all yelling at once, eventually it doesn’t matter how good the cell phone tower’s ears are, it will just sound like a loud buzzing sound, just like the crowd does when it’s cheering or booing the sports team. The tower can’t hear you, so neither can the Internet.
