CRFS RFeye Spectrum Monitoring Systems

CRFS Spectrum Monitoring Systems are scalable, low cost data collection networks based on RFeye, broadband, intelligent, GPS-enabled real-time spectrum analyser nodes

Designed for fast spectral analysis from 10 MHz to 6 GHz (10 MHz to 18 GHz using optional block down converter), and housed in a small lightweight housing suitable for use in both indoor and outdoor environments, the RFeye nodes can be deployed in both fixed or mobile applications.

A built-in Linux PC permits autonomous operation, and high-accuracy GPS provides accurate position and time stamping to allow correlation of data between different RFeye nodes. Data may either be stored locally, transmitted over the air via the built-in GPRS/HSPA modem, or downloaded via standard wired interfaces to a centralised database.

The capabilities of the RFeye node are key to providing a cost-effective system that can provide continuous, 24/7 monitoring of the radio spectrum:

  • Rugged, lightweight, compact, low power, fixed or mobile installation
  • Fast digital sweep (20 MHz instantaneous bandwidth) captures transient signals significantly more effectively than swept analysers or scanning receivers
  • Wide frequency range: 10 MHz to 6 GHz (18 GHz with optional block down converter)
  • Multiple RF ports to support multi-antenna operation
  • Designed for unattended operation – built-in Linux PC supports user-programmable scan sequences and selective, intelligent (/adaptive) data acquisition
  • High-accuracy GPS for location identification and inter-device time synchronisation
  • Flexible network connectivity: data download over the air via built-in GPRS/HSPA modem or via fixed-line interfaces, or local data storage via USB memory device
  • Secure network connectivity using SSH technology
  • System architecture optimised for flexible real-time signal acquisition and data processing
  • Centralised node control, monitoring and data capture: seamless integration with RFeye Spectrum Management System
  • Signal characterisation options
  • Signal Location estimation (DF) using AOA (directional antennas) and TDOA (correlation of signals between nodes)
