Passive DAS Monitoring
Keep-alive signal tracking for every antenna. A small probe at each antenna reports back through the existing feeders, so a break is found before complaints build up.

How it works
Supervise the DAS path itself.
- 01Send
Probe sends its ID keep-alive.
- 02Travel
Back through the existing DAS path.
- 03Receive
Gateway at the head-end splitter.
- 04Analyse
Missing messages or falling levels.
- 05Alert
Alarm sent northbound to the NOC.
- 06Dispatch
The right team goes to the right point.
Fault localisation
Missing messages locate the fault.
| What we see | Where the fault is | Who to send |
|---|---|---|
| One probe goes silent | That antenna, its jumper or connector | Technician to that antenna |
| All probes on one branch go silent | Splitter, coupler or trunk cable | RF engineer to that branch |
| All probes go silent at once | Head-end splitter or gateway | Check the equipment room first |
| A level drifts down over days | Connector, cable or water ingress | RF engineer with DTF / TDR tester |
