4G Cell Phone Jammer
Nowadays everybody has own mobile phone. We make calls; write messages; store documents, different files and pictures. Mobile phone is our right hand. But a lot of people forget that not everywhere the use of mobile phone is allowed. For instance, libraries, theatres, cinemas, schools, universities are places where the usage of mobile phone should be limited.
4G jammers were invented to block signals transmitted by mobile phones such as 4G Wimax and 4G LTE. This device disables phones to receive and send SMS, get calls and connect to the Internet. Phone blockers are very popular at schools and universities and used during lessons and exams. If you are a teacher, you know for sure how the average lesson looks like – pupils chat with each other on the social networks, read the information that does not refer to the subject, play games, etc. Sometimes it is too difficult to make them be focused on what you are telling. That’s why if you want to make an end to these constant SMS writing and Internet surfing, install a desktop or portable 3G 4G phone blocker. Students will not be able to use their mobile phones during lessons.
Also cell phone jammers are used in the offices or in the meeting rooms. Businessmen understand how important it is to keep in secrecy the internal information of the company. If you have a serious meeting where you and your colleagues discuss important business issues, it is better to switch on 4G phone blocker. In this case, strangers will not hear your conversation and your meeting will not be interrupted by calls.
If you work at theatre, cinema, library, nightclub or you hold the special event and want to make the audience to keep quiet, buy a phone disabler. You will be convinced that no mobile phone rings and distracts the speaker.
The working radiuses of 3G and 4G cellphone jammers are different. Some of them block signals within 15 meters, and some of them disable mobile signals within 100 meters. That’s why you have to pay great attention to the technical specifications of each item and choose the product which meets your specific requirements.
