Mobile communication jammer

Product features:

Ø Effectiveness:Can effectively block 2G, 3G, 4G, and 5G wireless signals from China Telecom, China Unicom, and China Mobile, supporting all frequency bands; Effective for all mobile terminals within the target area, the blocking effect does not depend on the working status and function of the mobile terminals, as well as the internal mechanisms of the communication system (such as cell selection and reselection mechanisms);

Ø Not affecting physical health:Low transmission power, with an average EIRP of no more than 5W for interference signals, meeting the requirements of the "Electromagnetic Environment Control Limits" (GB8702-2014) for public exposure control limits;

Ø Large effective shielding range:When the signal strength of the base station is near the "excellent point" and "midpoint", the effective shielding distance (area) of a single device shall not be less than 15 m (300 m), respectively²）And 30 meters (1000 meters)²）, which is 4 (15) times that of traditional jammers, meeting the wireless signal shielding needs of medium-sized conference rooms and most large conference rooms;

Ø Minor impact on normal communication:Not interfering with the uplink of mobile communication systems, only interfering with downlink pilot/reference signals/synchronization signals, can greatly reduce the impact on normal communication outside the controlled area;

Ø Intelligence and adaptability:Automatically analyze surrounding wireless signals, search for surrounding base stations, decode downlink signals from base stations, and generate suitable interference signals based on the obtained information;

Ø Networking and collaboration between devices:Supporting communication and control functions between devices, multiple devices can automatically collaborate to meet the wireless signal shielding requirements in large conference rooms and other complex scenarios;

Ø Fault diagnosis:The device supports fault diagnosis function, including circuit abnormal operation alarm, temperature out of range alarm, and other software and hardware error and fault alarms;

Ø Simplicity:Equipment deployment is simple, and it can be located near strong base station signals such as doors and windows; Only one button is needed for use; Provide a "start/pause" interference signal transmission switch, which does not require turning off the power during conference breaks;

Ø Applicability:It can be applied to various indoor signal shielding scenarios, such as large and medium-sized conference rooms, courts, prisons, music halls, examination rooms, examination marking centers, as well as other public places, military venues, government agencies, enterprises and institutions, important materials and dangerous goods storage centers, etc.
