Passive 4G&5G Interceptor
Vehicle‑mounted passive counter‑communication solution for national‑security missions, covertly intercepting and decrypting LTE (4G) and NR (5G) mobile‑network traffic within sensitive operational zones.
Highlight Features
Pure Passive Downlink Capture
Covert receive‑only interception of base‑station down‑link signals; no RF transmission to avoid detection by target mobile devices.
4G LTE & 5G NR Decryption
Matches over‑the‑air captured traffic with core‑network cryptographic keys to restore voice, SMS and internet‑session content.
Core‑Network Key Extraction
Retrieves cryptographic material via S1 / S6a MME interfaces to feed the local decryption‑server module.
Built‑In Secure VPN Transport
Gigabit‑grade embedded VPN for encrypted remote transmission of collected intelligence towards backend analysis‑nodes.
Dual‑Mode Operation
Switch between mass‑network‑wide monitoring or focused targeted‑subscriber tracking with terminal‑parameter collection.
Scalable Target Capacity
Target‑control and analytics resources can be horizontally scaled to adapt to varying‑scale field‑mission requirements.
Vehicle‑Deployed Hardware
Compact rack‑style interception unit optimized for vehicle‑mounted tactical reconnaissance deployments.
Full Traffic Logging & Analysis
Record complete intercepted mobile‑traffic metadata and content for post‑mission review and intelligence‑processing workflows.
