1. Scenario Background
A city’s fire department manages 50 fire trucks, but struggled with critical gaps:
- No real-time visibility of each truck’s emergency light/siren status (blind to on-duty status)
- Navigation tablets’ Wi-Fi often dropped (missing time-sensitive dispatch routes)
- Inaccurate GNSS location data delayed emergency deployment
2. Product Selection
InHand
VG710 In-Vehicle Gateway — built for mission-critical fleet scenarios:
supports GNSS positioning, 24/7 LTE/Wi-Fi connectivity, and I/O
interfaces to link on-truck devices.
3. Core Pain Points
- No real-time monitoring of 50 trucks’ emergency light/siren status
- Unreliable Wi-Fi for navigation tablets (missed dispatch routes)
- Inaccurate GNSS location slowing emergency scheduling
4. Solutions with VG710
- Status Tracking: VG710’s I/O ports connect to each truck’s emergency light/siren; real-time status data is sent to the Fleet Management System (FMS) via LTE.
- Stable Navigation: VG710 provides 24/7 uninterrupted Wi-Fi for on-truck tablets, linking to the dispatch system (via LTE) to receive routes instantly.
- Precise Positioning: VG710’s built-in GNSS uploads 2-meter-accurate location data to FMS, showing real-time truck positions.
5. Implementation Results
- 100% real-time visibility of emergency light/siren status (no more blind spots)
- 0 Wi-Fi dropouts for tablets — dispatch routes are received within 3 seconds
- Emergency deployment time shortened by 20% (faster incident response)
