Understanding Sensos Geofencing

Geofencing is a technology that defines virtual boundaries, enabling software to trigger actions when a device enters or leaves a specific area. In the context of supply chain management, Sensos utilizes geofencing to enhance shipment visibility and security, helping businesses stay informed about key transit milestones.

How Sensos Leverages Geofencing

Sensos employs geofencing to track critical shipment events, such as departure from an origin, arrival at a destination, and entry into specific zones along the route. These automated triggers keep you updated on shipment progress without manual intervention.

Key benefits of Sensos geofencing include:

Enhancing Security: Detect unauthorized stops, deviations, or delays.
Route Optimization: Analyze movement patterns to identify more efficient transportation routes.
Improved Efficiency: Automate notifications when shipments enter or leave key locations.

Precision Matters: New Geofence Logic

Sensos geofencing logic aims to deliver more accurate and reliable event detection based on location data quality.

Our approach adapts the geofence radius based on the location source (Cellular, WiFi, or GPS), improving precision and reducing false alerts.

Cellular: Suitable for wide coverage but less precise – larger radius.
WiFi: Moderate precision – medium radius.
GPS: Most precise – smallest radius.

These base radii are added to any custom radius or Point of Interest (POI) radius to ensure consistent, accurate results, even when location data is less accurate.

How the Updated Geofencing Logic Works

Shipment Departure

Detects when a shipment leaves its origin.

Cellular: Base radius 4 km (~2.5 mi)
WiFi: Base radius 1 km (~0.6 mi)
GPS: Base radius 500 m (~0.3 mi)

Example:
If your origin is a Point of Interest (POI) with a 1 km (~0.6 mi) radius and the location source is Cellular, the total radius is 1** km + 4 km = 5 km (~3.1 mi)**.

Shipment Arrival

Detects when a shipment reaches its destination.

Cellular: Base radius 1 km (~0.6 mi)
WiFi: Base radius 500 m (~0.3 mi)
GPS: Base radius 300 m (~0.2 mi)

Example:
If your destination is a POI with a 600 m (~0.37 mi) radius and the location source is WiFi, the total radius is** 600 m + 500 m = 1.1 km (~0.68 mi)**.

Custom Geofence

Monitors when a shipment enters or leaves a custom-defined area.

Base radius depends on location source (same values as Arrival).
Any custom radius and/or POI radius is added to the base radius.

Example:
If you set a custom geofence with a 400 m (~0.25 mi) radius, and the location source is GPS (300 m base), the total radius is 400 m + 300 m = 700 m (~0.43 mi). If the custom location is also a POI with a 100 m radius, the total becomes 400 m + 100 m + 300 m = 800 m (~0.5 mi).

Why It Matters

Better Accuracy: Tailoring geofence size to the location source reduces false triggers and missed events.
Clearer Setup: You no longer need to guess the right radius—Sensos automatically accounts for location source and combines it with your custom or POI radius.
Future-Proof: As more shipments use Points of Interest (POIs) for accurate origin and destination tracking, this logic ensures seamless integration.

Geofence Creation and Management

Sensos geofencing is already helping reduce cargo theft by tracking the use of authorized parking areas. Learn more here.

Looking ahead, Sensos Sync will allow users to define and manage geofences through the Points of Interest (POIs) feature, enabling businesses to create custom boundaries that match their operational needs.
Note: Location data is used only for triggering geofences; it is not logged or stored for other purposes. By leveraging geofencing with location-adaptive precision, Sensos empowers supply chain leaders to improve visibility, reduce risk, and enhance operational efficiency.
