4G passive IMSI Catcher can realize precise positioning of 4G mobile user-terminals by listening to the wireless signal of the mobile phone. The device can simultaneously control 4 frequency bands, 8 carriers and 8 cells at the same time, with advanced algorithms and accurate decoding.

The device supports both TDD-LTE and FDD-LTE 4G signaling stacks, supports 4G full-band frequency band operation, and adopts a passive working mode, which can realize the precise location of 4G network standard mobile terminals in a 4G network environment.  supports all operating frequency bands of operators after customization.

The device searches for the target without the IMSI number, and can directly locate the mobile phone number. The number is fast and the positioning range is wide. The effective range is related to the coverage radius of the base station where the target is located. The larger the coverage of the base station, the greater the tracking and hunting range.

The equipment is highly intelligent, the operation is simple and intuitive, and it does not depend on a specific vehicle, so the work is extremely concealed. One device solves the 4G positioning needs of all operators. It has a high degree of integration, small size and light weight. The weight and volume of the host can be placed directly in the men's casual bag. The device RF efficiency is high, and the effective signal coverage distance can reach 300 meters; the device points good performance, stable and reliable.

After years of technical accumulation and professional research, our equipment working condition is stable, and the average failure rate is extremely low.
