Electronic Fence Signal Investigation Code Acquisition System

"Electronic fence" is widely built in the important checkpoints of highways, national roads and city ring roads to make an overall analysis on the vehicle information and the cell phone information of the personnel inside the vehicle with the traffic probe, comprehensively master the traces of the roving suspects, expand the information source of technical investigation and the view of investigation. It is conducive to the public security organs to solve both the problems of migrant population and position control. Through the construction of the "investigation code project", the specific object can be set as the target. Once the object accesses to the region, the background analysis system of the "investigation code project" can sound a warning and provide a certain case handling basis for technical investigation. Combined with the road checkpoint system and other case handling systems of technical investigation, it creates the conditions for precise strike.

Electronic Fence Type Selection

4G FDD-LTE and TDD-LTE only collect the mobile ISMI information

FDD equipment has a standard configuration of single carrier, and only obtains the single frequency band (Band3 or Band1) mobile IMSI information of Operator A or FDD-LTE of Operator C; if you access the IMSI information of Operator C and Operator A, you need to configure the dual carrier module, namely FDD (Operator C) + FDD (Operator A).

TDD equipment has a standard configuration of single carrier BAND38 or 39 or 40, and the equipment configuration is based on the site environment.

FDD-LTE electronic fence: the single carrier configuration can get the mobile IMSI information of Operator A or Operator C FDD users in the coverage area.

The dual carrier configuration can get the mobile IMSI information of Operator A or Operator C FDD users in the coverage area.

That is, access to the 4G Operator C and Operator A IMSI information.

TDD-LTE electronic fence: the single carrier configuration can get the mobile IMSI information (designated frequency band) of Operator B users in the coverage area.

Note: The single carrier mode can only get the mobile IMSI information of a single frequency band as stipulated by the operator; the multiple carrier modules are required to be added to the multiple frequency bands.
