The Nexus 8
The NEXUS 8 range of LoRaWAN™ gateways combine a highperformance LoRaWAN™ radio with multiple back-haul technologies, simplifying the deployment of IoT networks in urban and rural areas.
The 8-channel low-power long-range LoRa® ISM-band radio is suitable for coordinating thousands of IoT devices within a radius of up to 25 km.
Off-the-grid rural or difficult urban deployment is straightforward using the Nexus8 Field Station, supplied with an IP67-rated enclosure and solar power system.
The built-in multiconstellation GNSS can accurately locate the gateway and assists with gateway time synchronisation and radio transmit frequency calibration.
The Embedded Linux operating system which powers the gateway is fully open to the user, enabling custom configuration and application installation.
