Last week I ate rice with my friends. The topic of telephone is booming. Smartphones change our lives. Brings a lot of convenience. However, there are many problems. Mobile phone etiquette is often a problem on trains. I often hear the announcement "Please turn off your mobile phone". It has no effect at all. At such times, there are people who want to block radio waves. In order to meet the demands of these people, a mechanism called out-of-service equipment was developed.
These days, this device is very popular. It makes my life very convenient. It may be a violation of smartphone etiquette. By using a device that makes the phone unusable, we solve various problems with the phone and create a comfortable space. Ideal for solving mobile phone etiquette problems. Introduce a mobile jammer at the test site. Blocks radio waves during the test time. Smartphones cannot communicate. Prevents cheating. Such devices are working in places outside the service area. You can be kind to people with this product. I think it's a little nice.
It gave the possibility of providing communication on smartphones to all places. Many people use mobile phones while driving. Improper use can cause trouble. Mobile jammers will reduce the number of car accidents. There is a significant risk of talking on the phone while driving. This is one of the reasons for designing a portable jammer that interferes with radio waves. It thinks twice before using the phone. Communication can be reliably prevented. Great effect is expected.
