According to statistics: the global mobile phone coverage rate has exceeded 80%, the elderly in the 1960s and 1970s,and the children to the age of three or four, all use mobile phones. Old people use mobile phones to chat with their children, watch videos, children use mobile phones to chat, grab red packets, play games and so on. And children use mobile phones at such a young age, and even can't do without mobile phones, which is not conducive to their growth.
In today's fast-paced technology era, there is demand for supply, and people are producing smartphones for the elderly: they can adjust the fonts large enough and the sounds are clear enough so that they can easily get in touch with their children and relatives via mobile phones. . Second, mobile phones can also provide them with entertainment to help them spend their free time. However, things have two sides, which makes some people feel very upset.
We know that these phones have large speakers, it will be very loud when they connect to the phone, so that loudly calls will disturb other people, causing them a lot of noise, even affecting the lives and work of others. Some people use cell phone jammer to block cell phone signals and stop loud, which sounds like a prank. What if people have important things? Therefore, when purchasing the jammer, it should be used reasonably, and should not be used for other improper purposes.
Mobile phone jammers are typically designed for confidential mechanisms and can interfere with multiple signals simultaneously. When the instrument is in operation, the mobile phone within the interference range cannot be connected or dialed. It is mainly used in the test site, church, library, military base and other places where mobile phones are prohibited. At the same time, it can protect the security of information and prevent hackers from invading, and the elderly have a weak sense of security and are vulnerable to telephone fraud, which is easily exploited by criminals.
