The power of jammers shield is fixed

  The shielding radius of the unobstructed space is determined by the path attenuation and the signal level of the receiving base station. In order to realize the interference of mobile phone signal jammers to the mobile network, it must be ensured that the signal field strength sent by GPS jammers is stronger than the field strength of the mobile signal in the interference area. The closer the interference location is to the base station, the stronger the field strength and the smaller the effective interference area, and vice versa. The farther the interference site is from the base station, the weaker the field strength and the larger the effective interference area.

  It can be seen that within a certain transmit power, the interference range depends on the field strength of the interference area. No matter how strong the shield is, as long as the transmit power is constant, as the distance increases, the strength of the interfering signal will gradually attenuate, thus losing the ability to interfere. The output channel power of the masker, the signal level of the base station, and the gain of the coverage line can determine the theoretical coverage radius with a reference value.

Adjustable 8-Antenna Cell Phone Signal Jammer

A jammer capable of jamming higher WIFI frequencies operating on the 5GHz spectrum. The 5GHz band operates in three standards: 802.11ac, 802.11a, and 802.11n. The 5GHz band is becoming more and more popular now because it gives you faster speeds, fewer disconnects, and a more enjoyable experience. Another advantage of a 5GHz signal may be the ability to go where 2.4GHz cannot due to the size of its waveform.

Portable Desktop GPS Cell Phone Jammer

I don't own an RF meter but was able to conduct a test on this that assures me that it's blocking the RF waves as it states. Whenever I have my phone on my desk, I get a lot of static out of my computer speakers, which I've determined to be from my phone (easy test, move phone closer, static increases; move it away, static decreases)...
