1 Introduction

1.1 What is the LG308

The LG308 is an open source LoRaWAN 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.



The LG308 is use semtech packet forwarder and fully compatible with LoRaWAN protocol. It

includes a SX1301 LoRa concentrator, which provide 10 programmable parallel demodulation paths.

LG308 has pre-configured standard LoRaWAN frequency bands to use for different countries. User

can also customized the frequency bands to use in their own LoRa network.

LG308 has optional built-in LoRaWAN server. System integrator can use it to integrate with their

existing IoT Service without set up own LoRaWAN server or use 3rd party LoRaWAN service.

2 Access LG308

2.1 Access and Configure the LG308 via WiFi or Ethernet

The LG308 is configured as a WiFi Access Point by factory default. You can access and configure

the LG308 after connecting to its WiFi network, or via its LAN Ethernet port.

WiFi

At the first boot of LG308, it will auto generate an open WiFi

network called dragino-xxxxxx

You can use a PC to connect to this WiFi network. The PC will

get an IP address 10.130.1.xxx and the LG308 has the default

IP 10.130.1.1

Ethernet

Alternatively, you can connect your PC to the LG308 LAN port

via Ethernet cable and obtain an IP address via DHCP.

Web Interface

Open a browser on the PC and type in the address:

http://10.130.1.1/
