Introduction 

1.1

 

What is LG02 & OLG02 

 

LG02 & OLG02 are an open source dual channels LoRa Gateway. It lets you bridge LoRa wireless 

network to an IP network via WiFi, Ethernet, 3G or 4G cellular. The LoRa wireless allows users to 

send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread 

spectrum communication and high interference immunity. 

 

LG02 & OLG02 have rich internet connection method such as WiFi interface, Ethernet port and 

USB host port. These Interfaces provide flexible methods for users to connect their sensor 

networks to Internet. 

 

LG02 & OLG02 can support the LoRaWAN protocol in single frequency and customized LoRa 

transition protocol. The design of LG02 is use the Linux to directly control two sx1276/sx1278 

LoRa modules which lets the LoRa can works in full duplex LoRa mode and increase the 

communication efficiency. 

 

LG02 can be used to provide a low cost IoT wireless solution to support 50~300 sensor nodes. 

 

Except LoRaWAN mode, LG02 can support multiply working mode such as: 

LoRa repeater mode

MQTT mode

TCP/IP Client mode

,

 TCP/IP Server mode

 to fit different requirement for IoT 

connection. Click this link for more info about the modes. 

 

LG02 & OLG02 provide a low cost for your IoT network connection. Compare to the cost with 

normal SX1301 LoRaWAN solution. LG02 & OLG02 is only of its 1/4 or less cost. This makes the 

LG02 very suitable to set up small scale LoRa network or use it to extend the coverage of current 

LoRaWAN network.
