FAQ
What are the limitations of satellite fallback tracking compared to cellular tracking?
Satellite fallback has several limitations: it requires a clear sky view (obstructions like dense forest canopy or deep valleys can block signals), introduces latency of several minutes between updates, transmits only mi...

What is satellite fallback and how does it work for fleet tracking?
Satellite fallback is a backup system that switches fleet tracking devices from cellular data transmission to satellite transmission when cellular networks are unavailable. In practice, this means the device transmits on...

What are the power management considerations for hybrid OBD2 + BLE trackers?
While modern hybrids have smart power management, they can still drain vehicle batteries in older vehicles or those sitting unused for long periods (3+ weeks). The OBD2 module draws minimal power but can trigger low-batt...

What is the difference between OBD2 GPS location data and BLE tag location data?
OBD2 GPS provides standard satellite-based location accuracy within 5-10 meters, while BLE tag location is zone-based and inferred by proximity to the OBD2 device or other gateways. BLE tracking shows approximate locatio...

When should a small fleet avoid using a hybrid OBD2 + BLE tracker?
A small fleet should avoid hybrid trackers when operational decisions require guaranteed, time-synchronized data between vehicles and assets. If you constantly need to reconcile timestamps for proof-of-delivery or compli...

What are the main technical challenges with the hybrid OBD2 + BLE tracker?
The hybrid tracker faces challenges with BLE signals getting blocked in metal warehouses, creating two parallel data streams that don't always auto-correlate seamlessly, and latency differences between OBD2 GPS data and...

When should a fleet manager consider upgrading their entire tracking system for sub-5-second capability?
Upgrade becomes necessary when operational gaps—such as geofence alerts arriving too late, consistently inaccurate ETAs, or inability to prove real-time location for insurance claims or compliance audits—start directly i...

Can existing 4G LTE devices achieve sub-5-second updates?
Maybe, but not reliably. Many older 4G devices were designed for battery efficiency rather than constant data streaming. Success depends on the device's firmware capabilities, whether it can handle rapid data sessions wi...

What are the technical challenges of implementing sub-5-second updates at scale for a fleet?
Implementing sub-5-second updates at scale requires devices with cellular modems that can handle constant data bursts without draining vehicle batteries, consistent network coverage without dropouts during cell tower swi...

Why is sub-5-second tracking important for fleet operations?
Sub-5-second tracking eliminates operational blind spots that occur between longer update intervals. It improves driver safety and asset security by providing immediate alerts for geofence breaches or sudden vehicle move...

What are the two main approaches to implementing BLE cargo monitoring in service fleets?
There are two approaches: 1) Tune your existing process by tagging only high-value, high-risk items like specialized calibration tools, or 2) Redesign your entire asset accountability framework by tagging everything and...

Can weather or buildings cause false BLE cargo alerts?
Yes, dense urban areas or metal structures can potentially block BLE signals and cause false alerts. However, good systems use signal strength averaging and ignition-on triggers to minimize false positives. The real risk...
