CMAS All-in-One Smart Managed Access Cellular System for Military & Security

In the information age, mobile communication technology is developing at a high speed, and mobile phones have become an indispensable communication tool for people's daily work and life. The mass application in mobile phones has also brought many negative impacts on certain specific places, and the information security and confidentiality in specific places faces complex and severe problems and big challenge. It is an urgent problem that how to effectively control mobile communication terminals in specific secret places.

Helios Technologies developed and brings Helios® All-in-One Smart Managed Access Cellular System (MACS), compared to the traditional indistinguishable passive frequency interference shielding technology, the Smart MACS System enable aware-able, controllable, and manage-able for cellular communication of mobile phone in specific secret area, even also can take over and control the specific mobile phone in the specific area.

Helios® All-in-One Smart Managed Access Cellular System (MACS) is based on the standard 3GPP protocol. By simulating the cellular base station, it adopts induces all passing 2G, 3G and 4G mobile phone to register and access to the fake base station, so that the mobile phone resides on the fake base station and cannot communicate normally. The fake base station can obtain the identification information of mobile phone such as IMSI, IMEI, MSISDN, Range, Dwell Time, Logs Timestamp etc., and send back the MACS Cloud Data Center server by wireless backhaul or IPsec network, all data stored on cloud can be processed, analyzed and displayed for alarm display or other applications.

  • Automatically collect the identification information (like IMSI, IMEI, MSISDN, Range, Dwell Time, Logs Timestamp etc.) of mobile phone with power on status where pass or stay in the coverage of CMAS System
  • All-in-One compact devices design supports 2G/3G/4G handsets capture process
  • Monitoring the dynamic information/status of mobile phone in the confidential area
  • Enable blocking the cellular communication of all 2G/3G/4G handsets in the coverage of CMAS except for the handsets in the white list
  • Enable detection and discovery any mobile phone in specific secret area
  • Enable generate warning alarm message to supervisor and even transgressor through SMS or external LED Display upon detect new mobile phone in specific secret area
  • MSISDN number acquisition
  • Support black and white list
