When some customers consult us about the signal jammer device, they will put forward such requirements according to the needs of the application scenario: the product needs to be portable, preferably in the style of a suitcase, can be turned on and working at any time, and the occasion can be changed at will, and the built-in The battery is powered without the need for an external AC power source. As a manufacturer, in order to meet these functional requirements of customers, we specially tailor-made suitcase-style shielding equipment. Then, the customer's subsequent question came out: how much range can the mobile phone box-type signal shielding instrument cover?

According to the customer's initial idea, the appearance of this suitcase must not be too large and the weight must not be too heavy, so the selection of suitcases is subject to certain restrictions. Usually, its appearance and size can only be similar to common briefcases. And the weight must be controlled within 10Kg. Once the size and weight limits have been set, let's analyze: what are the essential components that must fit inside the suitcase.

The first essential thing is of course the host of the cell phone signal jammer, which plays a role of signal shielding, as well as the radiator and cooling fan that provide fast heat dissipation for the host. The second is the battery that provides power for the signal shielding device. If AC and DC switching power supply modes are required at the same time, you must also consider installing a switching power supply. The third important component is the antenna that emits shielded signals, and the antenna can be divided into omnidirectional antenna or directional antenna according to the requirements of use.

From the above analysis, it can be known that a set of suitcase-type signal shielding instrument, because the space of the box is limited after all, if so many important components are installed in the box, even if the components are arranged very compactly, it is still limited. In the suitcase, a super-powerful signal shielding device must not be installed.

How do I know the coverage of a suitcase-style signal jammer? This is closely related to the transmission power of the shielding module used inside. According to the current design plan of our manufacturer, the transmission power of a single module that can be installed in a suitcase is generally between 10-20W. Refer to the past According to the test data, using a signal jammer with a 20W power amplifier, if it is used with an omnidirectional antenna, in a standard test environment, its coverage radius is usually between 40-60 meters. If you switch to a directional antenna for testing, the signal shielding distance of the suitcase-type signal shielding instrument is generally between 50-100 meters in the main direction of action of the directional antenna.
