FAQ
How should a fleet manager redesign their recovery playbook for remote border zones?
A fleet manager should redesign the recovery protocol by shifting from reactive signal reconnection to proactive theft detection using dead-reckoning data from the last known heading and speed, combined with automated al...

What is the boundary condition where tuning internal device settings fails to fix recovery?
The boundary condition occurs when the stolen trailer is inside a structure that blocks all satellite windows, such as a metal shipping container or underground parking. No amount of signal search parameter tuning in the...

Why can a GPS controller fail to reconnect even when a stolen trailer stops moving?
A GPS controller can fail to reconnect if the stolen trailer enters a deep signal shadow or an intentional Faraday cage setup. In such cases, the controller cycles through search patterns using stored almanac data that b...

How does a GPS controller lose satellite lock near a remote border zone?
A GPS controller loses satellite lock when terrain features like steep canyon walls, mountain passes, or dense tree cover block line-of-sight signals. In remote border zones, the lack of nearby cellular towers that could...

Why can a GPS controller fail to reconnect even when a stolen trailer stops moving?
A GPS controller can fail to reconnect if the trailer enters a deep signal shadow or an intentional Faraday cage setup. The device cycles through search patterns using stored almanac data that becomes stale, extending th...

How does a GPS controller lose satellite lock near a remote border zone?
A GPS controller loses satellite lock when terrain features like steep canyon walls, mountain passes, or dense tree cover block the line-of-sight signals. In remote border zones, this problem is worsened due to the lack...

When should I replace my existing cold chain alert hardware?
When your current sensors cannot buffer data locally during network outages, or when the alert platform cannot tell the difference between a monsoon-related delay and a genuine cold chain breach, you should replace them...

How do I know if my cold chain alert thresholds are set too high?
If you are only getting spoilage notifications after a batch is already flagged during post-route compliance review, your thresholds are set too high and they are missing transient temperature spikes that happen during m...

Why is relying only on a temperature probe in the cargo area a mistake?
A direct temperature probe only reports cargo temperature, not the ambient condition inside the reefer unit itself. A partially blocked vent or failed compressor cycle can create a localized hot pocket the probe never se...

Can GPS tracking alone prevent vaccine spoilage in a cold chain?
No, GPS tracking without integrated temperature sensors can't detect internal reefer failures or ambient heat changes, so the cold chain alert system has to combine location data with temperature readings to offer real p...
