LoRaWAN Technology

What is a LoRaWAN tracker?

A LoRaWAN tracker is a low-power IoT device that communicates via Long Range Wide Area Network (LoRaWAN) to send telemetry such as GPS location, motion, or sensor data. Truvami devices like the tag S/L, tag XL, and nomad XS combine GNSS, WiFi, and BLE scanning for seamless indoor and outdoor asset localization.

How does LoRaWAN communication work?

Each device transmits data to LoRaWAN gateways, which relay messages to a network server. The server decrypts and forwards the data to Truvami's cloud application, where it can be visualized or accessed via the API. LoRaWAN's AES-128 encryption ensures secure end-to-end communication.

What are the benefits of LoRaWAN?

• Range: Up to 15 km in rural areas and 2-5 km in urban settings
• Low Power: Multi-year battery operation possible
• No SIM cards: Reduces operational costs
• Interoperable: Open LoRaWAN 1.0.3 standard
• Secure: AES-128 encryption and unique DevEUI identifiers
• Scalable: One gateway can handle thousands of trackers

Do I need my own LoRaWAN network?

You can use:

• Public networks (e.g., The Things Network, Helium)
• Private gateways installed on your premises
• Managed network services offered by Truvami partners

Device Capabilities

Which assets can I track?

Truvami devices can monitor:

• Vehicles, trailers, containers
• Industrial tools or heavy equipment
• Construction and agricultural machinery
• Livestock and field equipment
• Workforce and personal safety applications

The tag S/L is best for compact assets, tag XL for industrial environments, and nomad XS for solar-powered autonomous tracking.

What sensors are included?

Device	GNSS	WiFi	BLE	Accelerometer	Pressure	Light	Gyroscope
tag S/L	✓	✓	✓	✓	-	-	-
tag XL	✓	✓	✓	✓	Optional	Optional	✓
nomad XS	✓	-	-	✓	✓	✓	Optional

Can I enable Bluetooth manually?

Yes. Press the button for 5 seconds to enable BLE advertising for 5 minutes, or trigger it via a downlink command (Port 134). BLE can also be used for firmware updates with EFR Connect.

Battery & Performance

What is the expected battery life?

Device	Configuration	Estimated Lifetime
tag S/L	1 fix / day	~9 months
	1 fix / hour	~2.5 months
	1 fix / 5 min	~7.5 days
tag XL	1 fix / hour	~2 years
nomad XS	1 GPS fix / hour (no solar)	4-6 days; continuous with solar charging

Battery life is influenced by signal conditions, update frequency, payload size, and environmental temperature.

Can I recharge the devices?

• tag S/L: Rechargeable via USB-C or wireless pad
• nomad XS: Solar + charging pads
• tag XL: Replaceable AA lithium cells

Integration & Setup

What integration options are available?

Truvami supports:

• REST API: Fetch devices, positions, and telemetry
• Kafka Streams: Real-time event ingestion
• Webhooks: Event triggers (geofence, button press, etc.)

All devices and events can be queried using filters for time range, device groups, and uplink type via the Truvami API.

How do I configure a device?

Settings can be changed:

• Via LoRaWAN downlinks (Ports 128-135 for tag S/L)
• Through the Truvami Dashboard

Configurable parameters include:

• GNSS/WiFi/BLE enable flags
• Motion and steady intervals (IM / IS)
• Accelerometer sensitivity
• Battery reporting interval
• Buffer size (max 8128 entries for tag S/L)
• Batch transmission size (default 10)

Tracking & Accuracy

What positioning accuracy can I expect?

Method	Accuracy	Typical Use Case
GNSS	3-5 m (tag S/L, nomad XS), 5-50 m (tag XL)	Outdoor tracking
WiFi	10-20 m	Indoor positioning
BLE	Depends on beacon infrastructure	Proximity tracking
LoRa triangulation	100-1000 m	Backup mode

All devices use U-Blox M10 or Semtech LR1110 GNSS modules for high accuracy.

What happens if there’s no network coverage?

Devices buffer data locally and resend when connectivity is restored.

• tag S/L: Up to 8,128 positions buffered
• tag XL: Similar capacity
• nomad XS: Smaller internal buffer

Buffered messages are offloaded oldest-first, respecting duty-cycle limits.

Platform & Support

What features does the Truvami platform provide?

• Dashboard for live map and asset monitoring
• Role-based access and SSO integration (SAML 2.0, OIDC)
• On-premise or cloud deployment

What support and services are available?

• Documentation: Full API + device manuals
• Technical support: Email & ticket system
• Firmware update assistance via BLE

---

Can I test devices before deployment?

Yes. Truvami offers:

• Evaluation kits (ready-to-use devices)
• Pilot programs for larger-scale testing
• Sandbox API for integration validation
• Developer workshops for custom use cases
