ANDRE (Advanced Near-field Detection Receiver) is a portable broadband receiver manufactured by Research Electronics International (REI), designed for the rapid detection of transmitters located within the area being swept.
The device covers a frequency range of 10 kHz to 6 GHz (up to 12 GHz with an optional downconverter antenna) and tracks signal level changes over time, displaying results as a histogram on a 3.5-inch touchscreen. A built-in frequency counter instantly identifies the frequency of a detected signal and automatically adds it to a signal list, tagged as “friendly,” “threat,” or “unknown.”
ANDRE is used for the rapid detection of radio, infrared, optical, and wired (carrier current) transmission channels in premises, vehicles, and open areas, and to pinpoint a signal source by tracking rising or falling signal strength.
Detects:
✔ GSM bugs, Wi-Fi and Bluetooth transmitters, mobile phones.
✔ Radio microphones and hidden cameras transmitting over the air.
✔ IR and optical transmitters, as well as devices using the power line (carrier current).
✔ Jamming devices that create interference to disrupt communications.
