Cell Phone Signal Jammer Kit

The most feasible method is to test a variety of mobile phones on site. The detection should not be too one-sided: Use multiple mobile phones with multiple frequency ranges to test the shielding effect of Cell Phone Signal Jammer Kit on the spot. This is the most convenient, most trouble-free, and most feasible test method. Compared with the limitations of the mobile phone test software, and the need to convert after passing the professional instrument test, this method is the easiest for users to grasp. The method is as follows: prepare mobile phones with multiple frequency bands, including: China Mobile, China Unicom, China Telecom, 3G, 4G, and 5G, then turn on the mobile phone signal jammer and hold each mobile phone. cell phone jammer The installation position is to test the effective shielding radius of the mobile phone jammer from near to far. It is recommended that the user should test the shielding distance in multiple directions with the jammer as the origin at the same time during the test.

When checking whether the mobile phone is blocked, you should pay attention not to just check the signal grid number on the mobile phone, because the signal grid number on the mobile phone is sometimes false and does not represent the current mobile phone communication situation. At this time, we must not draw conclusions too early. This Cell Phone Signal Jammer Kit has no effect. Instead, you should dial the cell phone intermittently. You can try to dial a local toll-free number or a fixed landline number. If the call fails, it is judged to be still in the shielding range. Otherwise, the shielding range is exceeded. After the multiple frequency bands are all tested, the shortest shielding radius of a certain frequency band is selected as the effective shielding radius of the mobile phone signal jammer in this area. The position can be estimated based on this when carrying out a large-area honeycomb layout.
