Relay

The Relay function is based on a Class C LoRaWAN^® device and acts as a proxy to a Finder which, when paired with a Relay, runs as a 2-hop relay.  In this scenario, the Finder will have been previously deployed remotely either attached to a drone* or at a fixed strategic location*.

The Relay connects to your Smartphone running the TagRanger^® App using it's Bluetooth connection.  Once the Relay announces its presence to the remote Finder, a relaying link is established between the Finder and Relay.  This allows all Tag communications to be relayed to and from the App for visual mapping, warnings, control.

The relaying link supports all features required to perform a Find with a Tag (i.e., Locate and Range) but does not yet support Data Download or Hybrid Ranging.  Additionally, to conserve LoRaWAN^® airtime usage, the relaying link only receives UWB ranging updates every 30 seconds although this period can be configured by the user.

Refer to the Feature Set page for the full extent of the Relay capabilities.

The internal battery can be recharged using a microUSB cable and there is a multifunction LED to indicate operating modes. The LED can be disabled by the user through the configuration settings if not required.

Power is controlled by holding a magnet (supplied) against the Relay between the USB connector and the LED.

* Like any other radio system (cellular, satellite, VHF etc) LoRaWAN^® range is highly variable depending on the local environment.  LoRaWAN^® range between a Relay, Finder and a Tag has been demonstrated at 21km with an ideal line-of-sight scenario (hilltop to hilltop with no obstructions), but this will be reduced by trees, vegetation, buildings, hills and even the tagged animal itself.  Reduce the effects of blocking by deploying the Finder from as high a position as possible.
