Mobile 2G+3G+4G Full-Frequency Detection Equipment System

Mobile Code Detect System Stone 176℃ 0Comments

The mobile phone full-frequency code detection system is a product specially developed for public security and national security and other investigation departments. It can control certain key areas and use technical means to collect mobile IMSI ( international mobile subscriber identification) without notice. The identification code, the unique correspondence with the SIM card mobile phone number, IMEI, location, and time information are analyzed through the back-end software system and compared with the blacklist to determine the specific location of the suspect and bring more accuracy and accuracy to the investigation work. It is the convenient means for solving crimes case.

1.2  Feature

1.2.1 full-standard electronic fence.

GSM, CDMA, TD-SCDMA, WCDMA/LTE (industry leader in supporting 4G direct electronic fences), it supports multi-frequency in one machine.

1.2.2 Automatic Sweeping

Automatically sweep out the frequency points and PCI values of the target area, use different PCI values of the same frequency point to reduce interference, do not raise the noise of the macro station, and automatically perceive the changes of the surrounding mobile network.

1.2.3 Fast collection

Quickly capture within 1,000 meters all through or staying mobile phone user identification information (the distance is related to the environment and transmit power).

1.2.4 High Collection Efficiency

Automatic synchronization of base station clocks, high efficiency and accuracy of electronic fences.

1.2.5  Adjustable Power

Can control coverage and information collection range.

4  Working Principle

The mobile phone full-frequency code detection device simulates the broadcast-inducing signal of the operator’s mobile communication network (china mobile/ Unicom /Telecom and later it can upgrade to another ), so that mobile phone terminals in the standby state where are  around them will detect a change in the location area, thereby initiate a location area update process. The mobile terminal register and report IMEI/IMSI to the mobile code detect device, then it complete the collection of public network user terminal information in the coverage area, and then transmit the collected IMSI or IMEI in real time through wired or wireless backhaul. Background information collection center, the user can connect to the collection center through the client software and background management system to view the collected mobile terminal information in real time.

­5 Structural features

The system is divided into two parts: the antenna side and the equipment side. The antenna part is an omnidirectional antenna and a directional antenna (the two antennas are set according to customer requirements at the time of delivery).
