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 LoRaWAN 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: 100 mm x 65 mm x 19 mm (excl. mounting tabs)
Weight: 160 grams with batteries
Off-the-shelf AA size batteries:
The Oyster LoRaWAN uses 3 x “AA” size 1.5V alkaline or lithium batteries which provide a good balance between size and capacity.
The Oyster LoRaWAN 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.
10uA (micro amps)
Battery Life with Adaptive-Tracking
The Oyster LoRaWAN 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).
-20°C to +60°C
For operation in extreme temperatures, the Oyster LoRaWAN 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 LoRaWAN 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 LoRaWAN to operate where normal units will fail to receive GPS signal – like in a container stack!
The Oyster LoRaWAN 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 GPS and LoRa RF antennas tuned by the RF laboratories to ensure optimal performance.
3 Axis Accelerometer
The 3-axis accelerometer allows the Oyster LoRaWAN 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)
LoRaWAN 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.
