Communication Interruption

Forces target devices to operate exclusively on 2G networks, delivering three key capabilities:

·        Data Service Denial:Blocks all internet access and mobile data services

·        External Communication Cutoff:Severs external communication channels to isolate target devices

·        Emergency Connectivity Reserved:Maintains basic voice call functionality for emergency purposes

Application Scenarios

Designed to mitigate social impact during critical situations through targeted communication control:

·        Mass Gatherings:Prevents rapid dissemination of event-related information during public demonstrations or rallies, helping maintain social order

·        Emergency Response:Manages information flow during terrorist incidents to prevent the spread of panic and unverified reports

·        Security Operations:Restricts unauthorized photography and video recording in sensitive locations to protect operational security

Information Control Strategy

The system targets three key transmission vectors to effectively manage information flow:

1.     Mobile Network Connectivity:Controls the primary channel for data transmission and real-time information sharing

2.     Smartphone Recording Capabilities:Restricts unauthorized capture of photo, video, and audio content

3.     Public Curiosity & Information Security Awareness:Addresses the human factors that drive information dissemination and potential security vulnerabilities
