Optimizing Movement Sensitivity: What Short-Sea Freight Taught Us
Recent testing on short-sea freight revealed that high movement sensitivity improves device reconnection speed without increasing lost reports. Here’s what that means for supply chain visibility, and what we’re testing next for long-sea routes.
When configuring tracking devices for sea freight, one of the most debated parameters is movement sensitivity. Set it too high, and the device may wake up too often, draining battery and risking message loss. Set it too low, and you may face delayed reconnection and gaps in visibility. Finding the right balance is crucial for reliable, real-time supply chain execution.
The Experiment
To better understand this balance, we recently partnered with ICL on a shipment from Israel to the UK. Two configuration sets were tested:
- Set 1: High movement sensitivity
- Set 2: Mid movement sensitivity
All other settings remained identical, including a non-negotiable 30-minute movement report interval required by the customer.
The results were surprising:
- Labels configured with high movement sensitivity connected more quickly upon arrival at port.
- Contrary to expectations, there was no measurable difference in the number of lost messages between high and mid sensitivity.
- Even with the additional wake-ups caused by sea movement, performance was stable and reliable.
Why This Matters
Faster device reconnection at arrival directly translates into:
- Earlier data availability for logistics teams
- Smoother onboarding of shipments into visibility platforms
- Improved operational control without added risk
This finding challenges the assumption that higher sensitivity always increases noise and report loss. In fact, setting thresholds too conservatively may limit the value of real-time monitoring without offering additional reliability.
Implications for Short-Sea Freight
Based on these results, high movement sensitivity is recommended for short-sea freight shipments. It ensures faster reconnection at the end of the voyage without introducing downsides such as lost messages or reduced device performance.
Thinking Ahead: Long-Sea Freight
Of course, not all ocean shipments are alike. Longer voyages, such as trans-Atlantic or Asia–Europe routes, involve more turbulence and extended durations at sea. In these cases, higher sensitivity could result in unnecessary wake-ups, potentially impacting battery life and communication stability.
That’s why we’re extending this testing methodology to long-sea freight routes. The goal is to validate whether high sensitivity continues to offer advantages, or if mid or even low sensitivity settings become more efficient over longer distances.
Conclusion & Call to Action
For short-sea freight, the evidence is clear: high movement sensitivity delivers faster reconnection without any trade-offs. This insight gives logistics teams greater confidence in configuring their devices for optimal performance on regional maritime routes.
We’ll continue exploring how these findings apply to long-sea shipments and share results soon. In the meantime, you can explore the detailed configuration guidance in our updated Sensos Knowledge Hub.
