Factors that determine the size of the Free Cell Phone Blocker Software shielding range: the distance between the use site and the base station and how many meters the obstacle can block. The mobile jammer is not only related to its own transmission power, but also to the distance of the base station in the use environment (the base station is not limited to the large transmission tower built on the ground, there are also signal amplification antennas on the roofs of certain buildings and signal amplification distribution). Another important factor is barriers. If it is made of metal, it will be blocked directly; if it is a solid reinforced concrete wall, it will at least 10 times attenuate after penetration. Therefore, when installing cell phone jammer , you must first understand your surrounding environment and the area you use, and then decide which type of cell phone signal jammer to buy.
