Cell Phone Blocker Synopsis

The shielding range is proportional to the power. For low-power Cell Phone Blocker Synopsis , it is enough to install one in a room, and the shielding range is about 20 square meters; while for high-power mobile phone jammers, the shielding distance can reach 100-400 square meters, depending on the local field strength. Or whether you need to go through the wall to decide (some parents will choose to install cell phone jammer in their own room). Before buying, you need to know which signals to block. Ordinary mobile phone signal (2345G) can be selectively shielded. If only 2G or only 345G is shielded, it can be adjusted before leaving the factory. There are 2.4GWIFI, 5.8GWIFI, VHF, UHF and other frequency bands. The function of each signal frequency band needs to be explained here. To put it simply, 2G is the frequency band for making calls, and 2345G is the frequency band for mobile Internet access, so it depends on the specific shielding requirements for the frequency band.

Cell Phone Blocker Synopsis

The power supply method of the mobile phone signal jammer generally has a built-in lithium battery, which can be charged with a power adapter after use; the desktop test room is powered by 220V, and the vehicle is generally powered by 12-36V. The appearance of cell phone signal jammers can be divided into external antennas and built-in antennas. Generally speaking, since the antenna is external, the external antenna has more space and volume than the built-in antenna. One point; due to the lengthened antenna, the effect of the external antenna is more stable. Confirm that there is radio interference. We will test Cell Phone Blocker Synopsis externally mounted devices. As enemies adopt more powerful weapons, they will periodically find ways to block the signal. It uses radio jamming technology that interferes with the signal. The developed mobile phone jammer is equipped with an antenna. Try generating various interference signals. Smartphone jammers have good performance. Radio wave interference occurs when radio waves are emitted near a frequency band.
