1、 Performance index of portable jammer

Frequency range of portable jammer: common equipment supports the frequency range of 20MHz to 6000MHz, and some equipment can be upgraded to 6000MHz to 11GHz. Interference radius: in a transparent environment, the interference radius can reach 100m to 1500m, depending on the transmission power and antenna gain. For example, when a device has a strong signal amplitude (2G signal -40dBm, 4G signal -60dBm), the interference distance is not less than 100m, and it can reach more than 300m in most application scenarios. Transmission power: the transmission power of the equipment can be adjusted according to the demand, and the transmission power of some high-power equipment can reach hundreds of watts. Coverage band: support 2G, 3G, 4G, 5G, Bluetooth Wi-Fi 2.4G/5.8G、 Satellite telephone (Beidou, GPS, GLONASS, Galileo), wireless image transmission, remote control, walkie talkie, UAV flight control and other frequency bands.

2、 Application Scenarios of Portable Jammer

Military and national defense: block the enemy's communication, navigation or reconnaissance signals to ensure the concealment and security of our own actions. Public security: prevent illegal use of mobile phones or other communication equipment in large events, examination halls, prisons and other places, and ensure discipline and order. For example, in the examination room, the jammer can shield the mobile phone signal to prevent cheating. Anti terrorism and explosive disposal: block the detonating signal of suspicious remote control bombs to ensure the safety of explosive disposal tasks. UAV control: interfere with UAV flight control and image transmission signals, and force the UAV to land or return.

3、 Development Trend of Portable Jammer

Miniaturization and integration: With the development of GaN technology and modular design, the size and weight of the equipment are further reduced, which is easy to carry and deploy. Intelligence and automation: the equipment supports automatic scanning and identification of target frequency bands, automatic adjustment of interference parameters, and improvement of operation efficiency. Multi band and scalability: The equipment supports multi band interference, and the frequency bands can be combined freely according to customer needs, reserving upgrade space. High reliability and stability: the equipment adopts multiple protection circuits and automatic power regulation to improve its adaptability in harsh environments.
