The GeoSense+ Asset Tracking system is developed for indoor asset tracking and is based on BLE and LoRa network.

A tracked asset is labeled with a low cost BLE tag, which periodically broadcasts its status to nearby edge devices.

An edge device is responsible for collecting the status of the adjacent tags and forwarding these information with the edge device’s ID to the server via a gateway device.

A gateway device connects to the edge devices via an indoor wireless LoRa network and is responsible for communicating with a cloud server.

Features

• Proactively reporting asset location
• Room level asset localization
• Asset historical location query
• Indoor map for asset location display

The GeoSense+ Environmental Monitoring system can provide long-range, low cost connections of low power sensor.

With different sensor modules, users can monitor multiple useful environmental information like temperature, humidity, air quality, VOCs and water levels etc.

Our sensor node is highly modularized. A basic version of a sensor node can easily upgrade to a more advanced version by combining a variety of different sensors according to the user’s requirements.

Two connection methods are supported:

• LTE-M for the applications with a small amount of sensor nodes
• LoRaWAN for the applications with a large amount of nodes or in an area without LTE-M network coverage

Depending on specific connection method and sensor type, cost of each sensor node is in the range of 20 to 200 AUD each.

The GeoSense+ WIP/Job Progress Tracking system was originally developed from a cleaning and patrolling supervision solution, which assists to quantitatively evaluate the outcome of their employees' work.

Based on the cleaning and patrolling supervision solution, the system has been extended to a broader “progress tracking” system based on a target’s location information.

The hardware of this system consists of two types of devices: beacons and tags.

Beacons are fixed on points of interest. Tags are carried by people who are on duty.

The tag can detect a beacon when the carrier is approaching points of interest, then report the presence event to the server.

The server will record the event information and automatically mark the progress of a task at a certain point as “finished” and update the progress of the entire job according to the status of each point.

The costs of a beacon and a tag are about 10AUD and 50AUD respectively.

The GeoSense+ Outdoor Tracking system is designed for general outdoor object tracking applications such as fleet management, cargo and livestock tracking.

It can connect to the cellular network and upload its location and the data from the integrated sensors.

Tracking device is powered by rechargeable battery which can last for years working in low power mode.

Tracking device integrates Qualcomm’s most recently released IoT modem MDM9206 which enable the device to connect to both NB-IOT and LTE-M networks and support all GNSS systems, i.e. GPS, Beidou, Glonass and Galileo.

The cost of the tracking devices is about 150AUD each.
