How large a range can a suitcase signal jammer cover?

When customers consult about signal jammer instruments, they often have specific requirements based on their application scenarios. They prefer portable products in the form of a suitcase that can be easily opened and used at any time without relying on an external AC power supply. As a manufacturer, we have developed suitcase-style jammers to meet these functional requirements. However, customers often ask about the coverage of Cell Phone Jammers in suitcases.

Considering customers’ preference for small and lightweight suitcases, there are restrictions in terms of size and weight. Usually, the appearance and size of a suitcase can only be similar to a common briefcase, and the weight must be kept within 10kg. With these restrictions in mind, let’s analyze the necessary components that must be installed inside the suitcase.

The first indispensable component is the main unit of the signal jammer, which is responsible for blocking the signal. It is equipped with a radiator and a cooling fan to ensure efficient heat dissipation. The second component is the battery that powers the jammer. If both AC and DC power supply methods are required, a switching power supply must also be installed. The third important component is the antenna, which is responsible for transmitting the interference signal. Depending on the specific requirements, the antenna can be omnidirectional or directional.

From the above analysis, it can be seen that the internal space of the suitcase jammer is limited. Even if it is compactly arranged, it is difficult to accommodate all these important components. Therefore, it is unrealistic to install a high-power jammer in a suitcase.

The coverage range of the suitcase jammer depends on the transmission power of the installed jammer module. According to our current design, the transmission power of a single module in the jammer system is usually between 10-20W. Test data shows that using a 20W power signal jammer amplifier with an omnidirectional antenna, the coverage radius in a standard test environment is usually between 40-60 meters. If a directional antenna is used instead, the coverage distance of the suitcase jammer in the main direction of the antenna is generally between 50-100 meters.
