Overview

The TR01 is a LoRa signal repeater fitted with an external LoRa antenna. It transparently forwards data between positioning terminals in blind spots (basements, tunnels, terrain obstruction, behind large equipment) and the LoRa gateway, eliminating dead zones without deploying extra gateways. It integrates a 6000 mAh rechargeable Li-ion battery and a 5.5 V / 1.3 W solar panel in an IP68 enclosure, suited for long-term unattended outdoor deployment in scenic areas, plants and tunnels.

Key Features

As a LoRa signal repeater node, the TR01 automatically forwards data between positioning terminals in blind spots (basements, tunnels, terrain obstruction, behind large equipment) and the LoRa gateway, eliminating dead zones without extra gateways. It supports a unidirectional data flow from locators (positioning terminals) to the LoRa gateway, ensuring stable backhaul of personnel and asset location data.

The external LoRa antenna provides more stable transmission and reception. When direct communication between a terminal and the gateway is blocked by walls, terrain or equipment, the repeater establishes a stable indirect link that significantly improves network coverage. With a built-in 6000 mAh rechargeable battery and a 1.3 W solar panel, the device is tool-free, wireless and maintenance-free—suited for scenic areas, factories, warehouses, underground spaces and tunnels.

Operating Method (LoRa end device + repeater)

When a LoRa end device works with the repeater, it must transmit on the last channel of its current frequency band with spreading factor SF8; only then can the repeater receive the frame. After receiving, the repeater forwards the data on the current band, using the same channel and parameters as the end device. The LoRa gateway then receives the frame and uploads it to the positioning platform. Frames sent on other channels or with a different SF will not be picked up by the repeater.
