What is the reason for the very poor mobile phone signal in the cinema?

If you are like me, you will enjoy a good movie experience and you can pay high-priced tickets and popcorn. What I am not really grateful for is when other movie fans are using their smartphones throughout the show. Even the darkest screen can illuminate the entire corridor and interfere with the viewing experience of many people. I know this is really urgent, but the fact that her small screen lights up every 30 seconds means that my own experience and SMS conversations with people who are not very interested in movies are still waiting. finished. If you cannot safely and legally use mobile phone devices while driving (I agree to this), I think you can reasonably assume that the use of mobile devices is also prohibited in movie theaters. This is not a theater safety issue, but paying customers should have a significant impact on the decentralization policy of cell phone jammer devices used in theaters.

Anyone can buy a miniature pocket RF mobile phone jammer online for less than $100 and knock off the phone in a theater or a place where the head is ugly due to abusing smartphones. The vigilance of these smartphones was previously created on busy roads to keep commuters away from mobile phones. The problem is that the interference power is unpredictable in terms of output power and range.
