The market is full of so-called signal jammers. They are often offered as a reliable solution against listening. But…
Only a few people know that the use of a signal jammer, especially for GSM, is illegal. It applies to ordinary people, institutions, organisations and companies. GSM signal is a widespread signal for cell phones and mobile communication and if someone uses a GSM signal jammer, they do not block only their cell phone in the room but also within a wider perimeter. In a better case, they will block signals only in the adjacent flats and offices; in a worse case it can cover a larger area. It means that, in the area, nobody can communicate via their cell phones using the GSM technology, which means a threat in case of an accident or injury as it would be impossible to call ambulance. From this aspect, it is good that our legislation prohibits the use of signal jammers. On the other hand, it must be pointed out that, currently, there is a wide range of available possibilities for obtaining information and listening. By using a GSM signal jammer, you will not achieve any significant results. You can block certain spectre but there are still many other ways that will not be solved. We absolutely do not recommend signal jammers. And not just because they are illegal but also because they do not solve the core of the problem. They do not protect your communication and transmission of data and information.
