How Location Updates Work on the Crewfinder dashboard

The Crewfinder dashboard uses Bluetooth beacon signals to determine user location in real-time. Understanding how location transitions are tracked and updated can help users and supervisors interpret dashboard data with accuracy.

1. Zone Transition Workflow

When a user wearing the SOL-X Smart Watch moves from Zone A to Zone B, their location update follows this workflow:

• Initial Zone Display
  The dashboard shows the user in Zone A.

• Movement Begins
  As the user walks out of Zone A toward Zone B, the system continues to display Zone A for a short duration.

• Update Latency
  Location updates may take 15 to 60 seconds to reflect on the dashboard and the smart watch, depending on signal strength and quality.

• Zone Update Confirmation
  Once Zone B is confirmed via beacon scanning, the dashboard reflects the new location and triggers any GeoFence Alerts (if set up for Zone B).

Note: The transition time may increase if there is interference or poor connectivity in the environment.

2. Bluetooth Signal Scanning Logic

SOL-X smartwatches scan for beacon signals every 15 seconds to evaluate location. The platform uses a multi-step signal validation process to ensure accuracy.

Signal Strength Criteria

• Each zone has designated beacons.

• Signal strength is measured in dBm (e.g., -50 dBm indicates a stronger signal than -90 dBm).

Zone Update Conditions

This scan-based verification ensures that the system only updates location when it is confident about zone entry, minimizing false positives caused by weak or overlapping signals.

Example Timeline

Let’s say a user is moving from Zone A to Zone C, passing through Zone B:

• Zone A: Watch detects consistent strong signals from Zone A beacons → Location is Zone A.

• Zone B: Mixed weak signals from Zone B beacons → Does not qualify for update.

• Zone C: Two consecutive scans detect strong signals from Zone C beacons → Location updates to Zone C.
