1. Product overview
1.1 Description
Walrus is an IOT gateway based on LoRaWAN and target to LPWAN network. The GW could
support LoRaWAN Class A/C protocol and Wi-Fi IEEE 802.11b/g/n standard. The 2.4G
wireless transmission rate up to 150Mbps. Users could connect the GW to Cloud server via
Wi-Fi.
This gateway integrates a 1T1R 802.11n WI-FI module, adopts MT7688AN highly integrated
SOC master, contains a 580MHZ MIPS24KEc CPU, a 100M Ethernet port, 1 * USB2.0, LTE
module (some models). An SX1308 LoRa baseband processing chip is integrated at the same
time, which can support 8 multi-SF channels (SF12 to SF7), 1 single-SF channel and 1
high-speed GFSK channel. The output power can be up to 25dBm, and the sensitivity is
-142dBm @ 300bps. Under certain transmission cycle and data length conditions, a single
gateway can access tens of thousands of nodes.
Walrus is a smart, easy installation and high reliability device. Customers could setup a quick
LoRaWAN network for their LPWAN application with Walrus.
