In the modern world, situations sometimes arise when it is necessary to block communication in a certain space. For such purposes, a cell jammer is used, also called a phone blocker. It's no secret that a modern person, and especially young people, cannot imagine their life without a cell phone, but now the purpose of a phone is no longer what it was many years ago. Almost any information can be found with a smartphone. Not only you can listen to the environment over the phone, but information about the owner of the phone can also be collected from outside, which not only violates his privacy, but can also endanger his life and health.
GSM network was the dominant 2G network in the world. It defines how mobile phones interact with ground base stations. GSM frequencies have two channel bands. The GSM-900 and GSM-1800 bands are used in Europe, Africa and parts of Asia, while GSM-850 and GSM-1900 operate in the Americas.
3G, or third generation, is a mobile technology developed in 1999 that is more advanced than GSM technology. 3G is sometimes referred to as UMTS - “Universal Mobile Telecommunications System”. The latter name is used in Europe. 3G technology, along with the usual mobile services, allows you to use video communication services and go online much faster from your laptop. The cellular jammer can also block 3G communication, but due to the higher noise resistance, the blocked distance is much shorter than for GSM communication. The cell jammer can also jam GPS or Wi-Fi and Bluetooth signals.
While GSM and 3G connections offer many conveniences, there are many negative aspects as well. For example, eavesdropping on phones and data leaks while browsing the Internet. Most people know that the government listens to their conversations. And how do you protect your privacy? Of course there is a solution. To do this, you can use a 3G cellular jammer, which also blocks GSM communication. This will protect your phone from eavesdropping.
In schools, 4G connectivity allows students to surf the Internet, watch YouTube, chat with friends, and do many more at the same time. In some cases, this can be beneficial, but very often it has a negative rather than positive impact. Smartphones that students use in the classroom are highly distracting, so the information provided in the classroom is partially or not at all absorbed. Lack of information negatively affects grades and exam results. Another negative aspect is that there is no motivation to learn. During the test, it is enough to turn on the Internet, and all the answers will be at your fingertips. It is even possible to solve scientific problems. All you need to do is send a photo with assignments to a friend who understands the subject and receive a photo with solutions from him. To avoid such problems at school, a 4G signal jammer will help you, which will also block GSM and 3G communications.
Students is not an exception. During the session, invisible headphones for examinations that are connected to the phone are very popular among students. Students hear the dictated answers in their headphones during the call. The cell jammer blocks the connection, so no outgoing and incoming calls are possible, so students cannot use the headphones, and they have to pass the exams honestly.
In a theater or cinema, phone blockers can also be useful. When viewers use their smartphones in a movie or theater throughout a show or session, they inconvenience the entire audience. Even the dimmest light emitted by a screen can distract other viewers. There are also visitors who forget to turn off their phones, so a mid-session call can seriously ruin the experience for the entire audience. More daring viewers can also answer the call and start a conversation right during the session, which causes great discomfort for everyone around. Such circumstances can lead to the fact that a theater or cinema will lose its regular audience. To avoid all these inconveniences, the administration of the theater and cinema reserves the right to use mobile jammers during the session that will help stop the rude behavior of the audience.
Everyone must protect personal information, because, for example, information leakage during serious negotiations can lead to significant material damage and trouble. Intellectual property is very expensive today and this is one of the main reasons why it should be protected. Fraudsters and employees of competing companies use eavesdropping devices to steal sensitive data. To avoid such troubles, you should use a cellular jammer that blocks communication and prevents information leakage.
Thus, the signal jammer has many advantages. It protects against information leakage, ensures the assimilation of information in school, protects the market from undergraduate university and college students, and ensures an enjoyable time in the theater or at other events.
