Jammers – types and purpose
If you’ve ever heard of signal jammers https://jammersmart.com/, you might be surprised that they have a variety of uses.
When it is necessary to jam signals and avoid wiretapping telephone conversations, covert video surveillance, or transmitting location data to outsiders, the appropriate types of jammers should be used. Depending on the frequency of the tracking, the choice can fall on GPS, wifi, and other types of jammers.
These devices are designed to generate noise in a wide frequency range. For such a device to be effective, it must be powerful enough. However, in practice, the work of a broadband signal suppressor often does not give the desired result. This is because the generated interference dissolves in a wide frequency range, while the bug gives a strong narrow-frequency signal. On average, if such a jammer is used to suppress signals in one room, the tracking device will use only less than 0.01% of the total power. This makes broadband jammers applicable only in cases when you do not know the frequency at which the spy device operates.
Narrowband or low-frequency jammers can function on 1 to 3 frequencies at a time. This is a great option when the frequency of the bug is known. When turned on, the jammer begins to generate interference at a given range and effectively jams the signals from the spy device. Narrowband jammers show the highest performance against broadband devices, such as TVs.
This is the rarest variant of low-frequency jammers used in the 10-1000 Hz range. The oscillation generators affect pointwise the nodes generating the unwanted signal. For example, on the kinescope, speaker, etc. The efficiency factor in these devices is low and therefore preference should be given to the more powerful models (at least 300 W).
