1 Product overview
Walrus is a well-built full-duplex mode built byXX.
The carrier-grade LoRaWAN gateway series. Embedded in the Linux operating system, the
main control chip is the powerful ARM Cortex-A53 platform, with a maximum frequency of
1.2GHz. It is equipped with a 1x or 2x Semtech high-performance multi-channel LoRa
transceiver SX1301. The 2x SX1301 version of the gateway extends the original normal 8
channel to support 16 channels, and the gateway's node capacity will be 4 times that of the
8-channel half-duplex gateway.
The gateway can be connected to the LoRaWAN cloud server Ethernet or 4G/3G/2G network.
The internal GPS module provides high-precision PPS signals for device clock
synchronization. The gateway is embedded with the web configuration client, which can be
quickly configured and maintained through the wifi connection gateway for on-site installation
and troubleshooting. The gateway supports multiple modes of power supply. It is equipped
with an external high-reliability lightning protection industrial DC power supply. It also
supports PoE power supply, backup battery power supply and solar power supply.
