Example system / staged planning
One landscape.
Three stages of observation.
A proposed network adapted from a supplied KML plan: RF receiving positions, acoustic clusters around water sources, and corridor monitoring connected through a shared hub.
Names and geographic details are omitted. The diagram preserves counts and groups, with a conceptual layout that does not identify the location.
Schematic only. On smaller screens, scroll across the diagram.
All stages: one hub coordinates five RF positions and 107 proposed acoustic positions. RF re-ID is an optional additional sensing role, not an extra location in the supplied plan.
The proposed system
Different roles, added in stages.
| Stage | Plan | Example role |
|---|---|---|
| Shared hub | 1 position | Coordinate receivers, collect records, run acoustic inference and forward retained evidence. |
| 1 · RF array | 5 receiving positions | Discover emissions and test localisation from shared reception and calibrated arrival times. |
| 2 · Water sources | 6 clusters × 9 positions = 54 | Capture bird and bat activity around recurring ecological observation points. |
| 3 · Corridors | 53 positions | Extend acoustic observations along corridors and drainage lines. |
| Optional · RF re-ID | Additional recorders; no separate positions specified | Evaluate band-specific waveform recording at suitable RF positions. Co-location needs separate power, antenna and interference assessment. |
A possible observation journey
Keep distinct events
connected to their evidence.
An acoustic node captures a candidate call near a water source. The hub can classify it and retain the original for review. Observations at corridor nodes add context for investigating activity and movement.
Separately, the RF array looks for transient emissions. If multiple receivers capture the same usable signal with qualified timing, the system can investigate its origin. Optional RF re-ID recorders retain suitable waveforms for comparing later transmitter encounters.
Coincident acoustic and RF events do not establish a common source. Similar calls or emissions do not by themselves prove the same individual or device.
What this example establishes
A system concept, ready for questions.
The source supplies proposed positions and grouping. Acoustic role assignments and optional RF re-ID co-location are illustrative additions. There are 112 proposed sensing positions plus the hub, not 112 validated installations.
Coverage, tree suitability, radio paths, timing, power and capacity require field assessment. No exact geographic map, original KML, identifying labels or installation coordinates are published.
