LoRaWAN-OD Gateway Communication Device
The Walrus LoRaWAN-OD Gateway is a robust, full-duplex IoT gateway engineered for high-performance connectivity for outdoor use.
Powered by a Linux OS and a 1.2GHz ARM Cortex-A53 processor, it integrates 1x or 2x Semtech SX1301 multi-channel LoRa transceivers.
The dual-SX1301 variant expands channel capacity from 8 to 16, quadrupling node handling capability compared to traditional 8-channel half-duplex gateways.
