FAQ
Does improving cellular coverage fix container tracking gaps in manufacturing yards?
No. Cellular networks only transmit location data after the GPS module calculates it. If the GPS signal is blocked by metal structures, there's no location to transmit regardless of cellular signal strength. Improving ce...

What causes container trackers to show 'last seen' hours ago even when the asset is on site?
This is typically a cold start or signal blockage issue. The tracker lacks satellite lock when moving from indoor storage to outdoor yards, so it can't send new position fixes even though it's still powered. The data del...

Why do GPS trackers on returnable containers fail to show accurate locations inside manufacturing facilities?
GPS accuracy degrades severely indoors due to metal roofs and machinery creating Faraday cages that block signals entirely. Standard GPS can be off by 50-100 meters or show no location at all in industrial environments w...

What is the critical mistake teams make when evaluating GPS temperature tracker data?
Teams often assume that synchronized GPS and temperature data on dashboards means real-time operation, when in fact the data is historically reconstructed. This leads to making compliance decisions based on false synchro...

What's the final sign that I need a new cold chain tracking system?
When you cannot achieve simultaneous, real-time transmission of location and sensor alerts without resorting to firmware hacks that drain batteries or cause GPS dropouts, that indicates a hardware limitation requiring sy...

Can upgrading cellular plans fix GPS temperature tracker delays?
Usually not. The bottleneck is often the device's processing power and firmware logic, which determines what data to send first. Better cellular plans don't change the device's internal buffering behavior during weak sig...

How does data delay in temperature sensors risk cold chain compliance for pharmaceuticals?
Audit trails require immutable, time-synchronized logs. Delays break the chain of custody proof, making it impossible to verify if temperature was maintained throughout transit, which can lead to shipment rejection and r...

Why would a 2026 GPS temperature sensor show a location different from where the shock happened?
This mismatch occurs due to data packetization issues. The device stores shock event timestamps and GPS coordinates separately, then transmits them together in a single bundle when it determines the cellular signal is st...

What is 'score drift' in driver scorecard systems?
Score drift occurs when a driver's safety rating improves during known high-risk hours, like early morning fog. This happens because algorithms often weight simple mileage over the quality of maneuvers, ignoring critical...

When should I replace my driver scorecard software instead of trying to fix it?
Replace it when your internal fixes—like adjusting event thresholds or adding new report parameters—fail to change driver behavior or reduce incidents after two quarterly safety reviews. If the core system can't ingest a...

How many vehicles does it take for driver scoring errors to become a major problem?
Problems start creeping in around 50 vehicles when manual oversight becomes impossible, but systemic failure usually kicks in between 150-200 assets. At that scale, data averaging, delayed processing, and lack of individ...

What is the biggest red flag that my driver scorecard data is inaccurate?
A consistently 'good' safety score for a specific vehicle during periods of high driver turnover or on routes with known hazards. This indicates the software is only measuring basic compliance like speed limit adherence...
