Compact IP67 Battery GPS Asset Tracking on LoRaWAN Networks

Download the brochureDOWNLOAD THE BROCHURE

The Oyster is a compact, rugged battery GPS tracking device that has been designed for container tracking, tracking trailers, skip bins, and other assets where super-long battery life is required without sacrificing the frequency of updates and performance.

It is also available in cellular 2G, 3G and new Oyster2 4G Cat-M1 and NB-IoT versions.

The IP67 rated housing is rugged and UV stable, so the Oyster can be mounted on assets that are exposed to rain, dust and marine conditions.

By utilising the latest technology, the Oyster can operate in ultra-low power modes, and with an incredible battery life of up to 5 years the Oyster can be attached to assets and tracked without needing to change batteries. The Oyster has built-in antennas for GPS reception and for LoRaWAN communication, a 3D accelerometer, a high-performance GPS that can track both GPS and GLONASS satellites simultaneously and flash memory for storing non-volatile information.

The Oyster uses the LoRaWAN technology to give you coverage of your assets at a low data cost. The Oyster  is available in 868MHz and 915MHz versions to cater for the various LoRaWAN regions around the world.

The Oyster uses 3 x AA 1.5V “off the shelf” Lithium batteries. These are generally available at retail outlets from manufacturers like Duracell and Energizer. Industrial 1.5V Lithium AA batteries are also available at bulk pricing.

The Lithium batteries have excellent performance and capacity, and allow the Oyster to be used in extreme temperatures and climatic conditions that other tracking devices simply cannot operate in.

  • Hardware Features

    Low-profile IP67 rugged housing

    The housing screws together for easy assembly, and has 2 convenient mounting tabs. It also has ‘strap slots’ allowing the Oyster to be cable tied or metal strapped to an asset. It is low-profile making it easier to mount in the corrugation on containers or concealed on the underside of a trailer, for example.

    Dimensions:L 138 x W 72 x H 30 mm

    Weight: 160 grams with batteries


    Off-the-shelf AA size batteries:
    The Oyster uses 3 x “AA” size 1.5V alkaline or lithium batteries which provide a good balance between size and capacity.

    The Oyster should be fitted with off-the-shelf 1.5V Lithium batteries for operation in cold temperatures or if you want the greatest reliability and battery life. These are readily available from retail outlets, for example Energizer Ulitmate Lithium.

    Sleep Current:
    10uA (micro amps)

    Battery Life with Adaptive-Tracking

    The Oyster can be set to use Adaptive-Tracking technology where the accelerometer and GPS data are used to intelligently work out if it is moving and to send frequent updates, and to scale the update rate down to once per day if the asset is stationary - to preserve battery life.

    Up to 5 years @ one position per day (at 25°C).

    Operating Temperature

    -20°C to +60°C

    For operation in extreme temperatures, the Oyster must be fitted with Lithium batteries. Batteries are affected by temperature extremes and typical performance is dependent on temperature.

    High sensitivity GPS

    • Supports concurrent GPS and GLONASS
    • 72 channel high sensitivity receiver
    • -167dBm industry leading tracking performance
    • Optimal hot-start performance.
    • Autonomous AssistNow Offline aiding data for fast time-to-first-fix and performance in urban canyon environments


    The Oyster uses both the GPS and GLONASS positioning systems simultaneously. This allows the device to use twice the number of satellites to get a position fix – making it faster and more accurate.

    Low Noise GPS Amplifier (LNA)

    GPS signals are boosted by a special low-noise amplifier (LNA). This allows the Oyster to operate where normal units will fail to receive GPS signal – like in a container stack!

    LoRaWAN™ Communications

    The Oyster uses a high power radio transmitter / receiver that operates on LoRaWAN networks, and is available in variants for the various LoRaWAN frequencies around the world including AS923.

    Internal Antenna

    Internal GPS and LoRa RF antennas tuned by the RF laboratories to ensure optimal performance.

    3 Axis Accelerometer

    The 3-axis accelerometer allows the Oyster to ‘sleep’ in an ultra-low power state yet still wakeup when movement occurs.

    Future firmware versions will allow for harsh G-force detection (like assets being dropped or involved in accidents)

    Configuration Cable

    The Oyster caters for a USB configuration adapter and cable, which is used to program firmware updates and configuration information on the device. The most common configuration parameters are also able to be updated OTA via LoRaWAN downlink messages.
  • The Oyster is a stand-alone tracking unit and therefore does not have peripherals available.

    The Oyster requires a USB Configuration Cable in order to reprogram firmware or to configure the device. Configuration can also be done over-the-air using LoRaWAN™ downlink messages.

  • Firmware Smarts

    OTA Configuration

    The Oyster can be remotely configured and some of the key operational parameters updated via the LoRaWAN™ downlink messages.

  • Software and Data Managment

    Data from the Oyster device is sent to LoRaWANgateways, which in turn will report the data via their LoRaWAN cloud infrastructure to the back-end server platform for processing and reporting. The LoRaWAN network server is not provided by Digital Matter.

    There are several LoRaWAN network service providers for customers to choose from. Each of them have their own management interface and formats for providing data to a software platform.

    Please contact Digital Matter if you require information on the integration of the Oyster data payloads.

    User Interface:

    This can be Digital Matter’s Telematics Guru platform which has built-in support for the Oyster device and protocols, or to your own server platform. Please contact Digital Matter if you require information on the integration of the Oyster data formats.
