Signal jammer Manufacturers

Now the appearance of the shielding device has solved many hidden dangers of disturbing the order for the examination room, so that the examinees can take the exam in a fair environment. The principle of this test signal jammer is to make the communication signal of the mobile phone malfunction by isolating the electronic signal, which can eliminate the phenomenon of cheating by using the mobile phone.

There is an exploding market for the anti drone signal jammer, especially the portable anti drone guns, the handheld anti drone device, the anti drone briefcase, the drone counter trolley case, etc.

When the mobile phone is working, the mobile phone and the base station are connected through radio waves within a certain frequency range, and data and sound transmission is completed through a certain baud rate and modulation. In view of this communication principle, the wireless signal shield scans the low-end frequency to the high-end frequency at a certain speed during the working process. The scanning speed can cause code interference in the newspaper signal received by the mobile phone. The mobile phone cannot detect the normal data sent by the base station, making it unable to establish a connection with the base station.

On 25th November, our Italian customer bought the RF jammer module to do his own brief case wireless signal jammer case. He bought the wireless signal jammer module as below frequency VHF 135-175MHz, UHF 440-480MHz, 790-870MHz, 920-965MHz, 1800-1920MHz, 2400-2480MHz, 2620-2690MHz, except 135-175 and 400-480, others is average 30W. Besides, he bought the omni directional fiberglass antenna.

​Drones have become increasingly popular in recent years, but they can also pose a threat to privacy and security. In some cases, it may be necessary to block drones from entering a certain area.

ome jammers operate over a wide range of frequencies. These broadband jammers emit noise or signals across a broad spectrum, effectively drowning out the desired signals. This is often accomplished using wide band amplifiers and antennas that can simultaneously transmit over multiple frequency ranges.
