Should we choose high-power Signal Jammer or low-power Signal Jammer?

Should we choose high-power Signal Jammer or low-power Signal Jammer?

  • 2022-06-19

The shielding range of signal jamming equipment varies according to the difference of commodity power. The shielding half diameter of high-power signal jammers used in detention centers can reach hundreds of meters. However, the shielding half diameter of low-power signal jamming equipment used in examination halls and conference halls is generally 1-10 meters, depending on the compressive strength of surrounding signal communication base stations.

The shielding ability of high-power signal jammer is particularly strong, and the power can reach hundreds of watts. Suitable for prisons, detention centers and other unique places. However, due to its strong shielding ability, if it is close to residential areas, it will more or less affect the normal mobile phone voice call requirements of the surrounding environment. Therefore, this kind of signal jamming equipment is generally used in relatively wide areas far away from residential areas. On the contrary, the short power of the low-power signal jammer is more suitable for the classroom. If there is a communication base station in the campus and the mobile phone receives pulse signals ≥ -90dbm, the actual shielding effect of signal jamming equipment will be very good. There is no problem with the shielding distance of 10 meters. It is sufficient to put one jammer in one classroom.

Nowadays, more and more mobile phone signal transmitting base stations are assembled in cities, which makes the signal compressive strength of products better and better. Originally, the Signal Jammer could complete the shielding range with a radius of 10 meters. Now, the shielding radius is likely to be reduced to 5 meters. High power signal jammers have become a hot spot. This requires us to consider repeatedly when selecting shielding instruments.
