Modern society is often referred to as the information society because it largely depends on the continuous transmission of information. On the one hand, this is a very useful opportunity that has enabled humanity to achieve all the current successes. On the other hand, in such a society, hiding secret information is not easy because espionage activities no longer require special training, as an ordinary smartphone is enough for everyone. An excellent choice to prevent potential leaks is a relatively inexpensive multi frequency signal jammer.
Its uniqueness lies in its focus on interfering with as many communication channels as possible, in principle. At the same time, it is possible to block only one selected channel, or block all available channels simultaneously, resulting in an information vacuum. The spectrum available for interference varies depending on the selected model, but the most powerful sample can suppress the following transmission methods:
Standard civilian radio channels;
All mobile communication standards, from CDMA to all types of GSM, and then to modern 3G and 4G (LTE);
Wireless technology for connecting to the internet through Wi Fi;
Fix and send geotags through the most popular GPS and GLONASS systems.
Modern manufacturers even offer such devices in relatively portable versions - although weighing a few kilograms, some models can even be powered by batteries in cars. This allows you to be completely certain that no outsiders will convey what they hear or see to outsiders.
As for the scope of application, there are significant differences depending on the model, but the best prototypes can calmly "cover" an area of over 100 square meters, so even eavesdropping will not be so easy about secrets. It has been proven that in most cases related to confidential information, this is an indispensable device for any negotiation, from business to diplomacy, internal meetings, communication with secret counterparties, and so on.
A simple fact is that even those who do not like to provide free information about others have recently developed an interest in the most moderate sample. If the company name, revenue, and future depend on it, then choosing high-quality samples of such equipment is the direct responsibility of consumers.
