Node Apps

Node Apps are stand-alone embedded applications running on RFeye® Nodes providing 24/7, autonomous spectrum monitoring and capture for a wide range of spectrum operations.

Real-time Spectrum Monitoring

The CRFS embedded Node Control Protocol daemon (NCPd) serves up real-time spectrum data to the Apps for local processing on the deployed receiver Node providing a distributed, multi-mission capability on single or multiple Nodes within a spectrum monitoring network.
