In fact, this is not entirely correct. Many manufacturers use the status quo that ordinary users cannot detect the actual power, deliberately exaggerating the publicity of Cell Phone Jammer Kit Price power, causing the device's nominal power index to lose its reference value. For large mobile phone jammer systems, shielding technology is a decisive factor affecting the shielding effect. The advantages of advanced shielding technology are far greater than the output power factor of mobile phone jammer devices. In fact, the distance is not an absolute value. It is related to the strength and quality of the spatial signal. Simply put, distance is meaningless. For the same shielding power, if the distance is 100 meters-70 decibels at the weak point, then only 12.5 meters at the strong-52 decibels. cell phone jammer The shielding distance is related to the antenna gain. The same power shielding host uses different gain antennas, and the distance will be very different. For example, an antenna with a gain of 16 db has a distance of 100 meters, and an antenna with a gain of 4 db has a distance of only 25 meters.

The working principle of the mobile phone signal jammer is that within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method. So what are the characteristics of Cell Phone Jammer Kit Price ? The mobile phone jammer only shields the mobile phone signals in the test room, does not interfere with the mobile phones outside the test room, and will not interfere with the base station. It only shields the mobile phone signal and does not affect the normal operation of other electronic equipment. It only shields the transmitter of the base station. The downlink frequency does not affect the uplink frequency. The mobile phone jammer is simple to operate, install the antenna correctly, and it can run automatically when the power is turned on. It is green and environmentally friendly. The electromagnetic field strength is far lower than the national standard and has no impact on the human body.
