SeeHawk® Monitor System at a Glance
SeeHawk Monitor uses Remote Test Units, also known as RTUs, installed at radio sites or deployed in critical coverage areas. These RTUs monitor spectrum and radios, then send data to Platform Manager.
Platform Manager software can be used to:
- Remotely configure RTUs
- Schedule uplink testing
- Schedule interference monitoring
- Report test results
- Report radio metrics
- Report downlink performance
- Report interference problems
