What is the Jamming range of a cell phone signal jammer?

Choosing the right cell phone signal jammer is a challenge for many people. They may not be sure how to choose the right jammer for their needs. JAMMERSIGNAL recommends communicating with the jammer manufacturer and providing them with information about the intended application site and the coverage required. It is also important to consider whether there are signal towers operated by the service provider within a 500-meter radius, as this will affect the choice of jammer type. The following are key aspects to consider when choosing a cell phone jammer:

1.Interference range:

The range of the jammer depends not only on its own signal strength, but also on factors such as the distance between base stations in the application environment. Base stations are not limited to large signal transmission towers, but can also include signal amplifying antennas on rooftops or inside buildings. The presence of obstacles such as metal materials or concrete load-bearing walls also affects the range. Passing through such obstacles will cause signal loss, and concrete walls will cause at least ten times attenuation.

2.Magnetic field signal level:

The strength of the magnetic field determines the number of signal jammers required in a given area. When the magnetic field is weak, installing one jammer for every five classrooms may be sufficient. However, if the magnetic field is very strong, such as when there is a base station within 500 meters, 300 meters, 200 meters or even 100 meters, additional jammers may be required. It should also be considered whether there is a base station on the roof. The stronger the magnetic field, the more jammers are needed to effectively block the mobile phone signal.

3.Small range coverage (0-10 meters):

For areas within a small range of 0-10 meters, with a total area of ​​up to 120 square meters, it is recommended to use a low-power mobile phone signal jammer. The effectiveness of the shielding will vary depending on the distance between the site and the base station. It is strongly recommended to use a handheld jammer designed for 4G and 6G mobile phones in this range. It should be noted that low-power jammers may weaken the signal when passing through walls, and it is recommended to avoid purchasing low-power models if necessary. Popular GPS jammers and WIFI jammers in Europe and America.

4.No base station within 1 km:

In areas with no base stations within a 1 km radius, one device is generally sufficient to cover an area within 120 square meters. For areas of 120 to 250 square meters, it is strongly recommended to install two devices. In large and medium-sized conference halls, it is recommended to install one device per 150 square meters and two devices per 250 square meters. Installing more than three devices in one area will produce a cellular shielding effect.
