Why our cell phone no signal in cinema?

This is a problem that people who go to the cinema often will notice. We will find that, when we enter the cinema area, mobile phone signal will fade away until disappear. Often in the cinema, we find that the phone cannot be connected

First of all, we must understand, why will appear this kind of phenomenon. There is no doubt that this is to use a device called cell phone jammer. Then, we want to know, why the cinema will do this. There is no doubt that there are two purposes. One of them is to let the customer enjoy movies better, don't be disturbed. Another is in order not to let customers candid camera film.
