Why does the shielding range of signal jammers vary?

When purchasing a signal jammer, customers often ask about its shielding range, but the shielding range of a signal jammer is not fixed.

When the signal jammer is working, it will scan the channel from the low-end frequency to the high-end frequency at a constant speed. This scanning speed will disrupt the information signal received by the mobile phone, causing interference garbled codes, resulting in the mobile phone being unable to detect the normal microwave signal data transmitted by the base station, and thus unable to establish a connection with the base station, thereby achieving the purpose of shielding the mobile phone signal.

Simply put, the frequency emitted by the signal jammer will interfere with the ability of the mobile phone to receive the base station signal. The jammer and the base station are in a competitive relationship. If the transmission power of the signal jammer is lower than the power transmitted by the base station to the mobile phone in the current environment, the jammer will fail. Conversely, if the power of the Cell Phone Jammer exceeds the power transmitted by the base station, the signal can be effectively shielded. Therefore, the effective shielding range of any jammer will vary depending on the signal environment, including factors such as base station density, orientation, and power, and the shielding ranges of mobile network operators such as China Mobile, China Unicom, and China Telecom are also different.

That is to say, the range that a mobile phone signal jammer can block is not only determined by the transmission power, but also affected by the distance between base stations in the use environment (including transmission towers, signal extension antennas on buildings, and signal distribution within structures). Another important factor is obstacles. Metal materials will directly block signals, while solid reinforced concrete walls will cause greater attenuation, about ten times that of solid reinforced concrete walls. The signal attenuation is small after penetration by wooden boards or glass materials. Best-selling WIFI jammers and GPS jammers in Europe and America.

Therefore, when customers ask about the required shielding range, it is important to consider the distance between base stations in the use environment, whether it is indoors or outdoors, and whether there are obstacles such as walls.
