SEA 3714M
Cellular Measurement System

Detection of existing mobile radio infrastructures

The SEA 3714M Cellular Measurement System is a device that can measure up to 40 cellular networks in parallel to record the availability and propagation of cellular radio cells. It is suitable for the testing and monitoring of the 2G/3G/4G/5G/LTE-M and NB-IoT technologies.
All major cellular standards can be measured simultaneously, regardless of operator, access technology or frequency. Signal strength, frequency, cell ID or other parameters are recorded and stored together with the GPS position.
Continuous passive monitoring of mobile radio signals can provide detailed information about unknown infrastructure in the field.

SEA 3809M WLAN-Scanner

Military counterintelligence

The SEA 3809M is a brand-new military counterintelligence product for scanning available Wi-Fi networks and Bluetooth signals in the 2.4GHz, 5GHz and 6GHz frequency ranges. Metadata and signatures from Wi-Fi hotspots or smart devices such as smartphones and tablets can be detected and recorded. The portable unit is battery powered and can be operated manually or fully autonomously to monitor and report the presence of Wi-Fi and Bluetooth signal sources in unknown areas.
The SEA 3809M can be used to continuously monitor military areas or other government buildings to detect unwanted Wi-Fi or Bluetooth communications. Device metadata and communication data can be recorded in PCAP format.
IMSI detection via Wi-Fi honeypot capabilities to detect IMSI via Wi-Fi instead of cellular are available on request. The SEA 3809M can be fully encrypted to protect recorded data. Remote access to the system is possible via VPN. The SEA 3800M WLAN scanner offers automatic observation, creation of movement profiles and passive detection of the infrastructure in use.
