Key features of the TagRanger® System

TagRanger® offers the ability to find your Tag with its unique combination of GNSS, UWB Ranging and LoRaWAN technology. Users can remotely wake up a Tag device from a ‘Finder’ device using LoRaWAN to request GNSS location and when close, use the UWB Ranging technology to ‘home in’ on the Tag over a range of up to 150m in ideal conditions. The table below gives a detailed description of the capabilities and configuration of the system.


Technology Feature Specification Finder Tag Functionality
Smartphone App TagRanger® mapping and control interface Android version 8.0 or above (Oreo)

Runs on a smartphone and is paired with a ‘Finder’ to provide Tag communications, Tag management, mapping (online and offline), Tag notifications, configuration settings, and warnings.

Please note, an internet connection will be required to set up a (free) account for managing your system and backing up settings.  An internet connection is also required for downloading maps for offline use and updating system software. A WiFi connection to your Smartphone is all that is needed to support this.

Power Magnetic switch for power on/off Solid state switch

Contactless power switch and waterproof battery charging using microUSB ensure a reusable, rugged device rated to IPx7 ingress protection.

Exceptional power efficiency allows the Tag to operate for up to 4 years before requiring recharging (subject to the configuration profile).

Trial different Tag configurations in the App to optimise battery life

600mAh battery
Battery charging Standard MicroUSB charging port
Battery estimator Predict battery life based on your Tag configuration
Multifunction RGB LED LED for user feedback Multicolour, refer to LED states table

LED colours and flashing states give extensive feedback on what the Tag or Finder are doing.

The LED can be disabled completely, or after a specified delay to ensure covert operation on a deployed Tags or Finder.

Disable LED OFF/30mins/60mins/24hrs/Always
Bluetooth Low Energy (BLE) radio Communication interface with Smartphone 1Mbps

Your smartphone is paired with your Finder over the Bluetooth link for all operations (communication, control and configuration).

Bluetooth can also be used to directly connect to your Tag at power-on to manage configuration settings.

GNSS Multi-constellation positioning network receiver GPS, Galileo, BeiDou

GNSS locations can be logged on a customised schedule to internal storage or transmitted in real time over the LoRaWAN long range radio.

The highly configurable GNSS receiver allows you to optimise location speed and accuracy to suit your environment.

Multiple assisting modes are supported that will help to acquire a Tag location quickly which saves time and minimises battery use.

With up to 5 geofence definitions possible and control over what happens when in or out of a geofence, activity can be controlled to conserve battery.

Long Range Radio LoRaWAN protocol 868 & 915MHz 64 devices Gateway Function  

The long range radio is the primary mechanism for wake-up, location reporting, remote configuration updates and Tag operating modes. TagRanger® is a cloud-free solution operating without the need for constant internet connectivity or cloud infrastructure. This ensures reliable tracking and device control even in remote areas free of SIM card, subscriptions or network costs.

LoRaWAN range has been tested between a Finder and a Tag at 21km in an ideal line-of-site setup

If you have your own private LoRaWAN network you can seamlessly connect your Tags to it and even switch between the network and the Finder on demand.

Mounted on a drone or fixed in a location a TagRanger® Relay device can extend the range capabilities beyond the standard technology. This 'multi-hop' functionality ensures comprehensive wildlife monitoring across larger territories and challenging landscapes.

LoRa Device/Finder Device modes
Network join options OTAA/ABP/Hybrid, periodic rejoin and retries
Device wake up Proprietary LoRaWAN protocol extension
Programmable day/week/month with emergency fall back
Programmable transmit (ping) Ping on a schedule
Ping on event (activity, dropped tag, GNSS location)
Programmable day/week/month with emergency fall back
Switch configurations Remote change of device configuration (up to 5 banks)
Programmable data rate Manual selection or ADR (with private network)
Network switch Switch between private LoRaWAN Gateway or Finder Gateway
Ranging Radio Ultra-Wideband (UWB) Distance measurement up to 150m (line of sight)

TagRanger® offers precise finding with its unique combination of GNSS, UWB, and LoRaWAN technology.

Users can remotely wake up a Tag device from a ‘Finder’ device using LoRaWAN to request the GNSS location and when close, use the UWB technology to ‘home in’ on the Tag over a range of up to 150m in ideal conditions.

The UWB technology allows for high-speed and non-intrusive data download, ensuring efficient recovery of dense data sets without disturbing wildlife.

This can only be used within 25m of the Tag (adjustable).

Channel 3 or Channel 5 support
Data download (within 25m line of sight)
Accelerometer 3-axis, ±2g/±4g/±8g/±16g full scale MEMS device Off/Activity/Inactivity modes   The built in accelerometer can be used for motion alerts (mortality/dropped Tag events) or monitor activity patterns, contributing to in-depth behavioural analysis.
Settable acceleration range and activation threshold
Integrated with LoRaWAN ping-on-event setting
Temperature       The integrated temperature sensor provides valuable environmental data, enabling researchers to assess wildlife habitat conditions accurately.
