1Introduction
1.1 What is the LPS8
The LPS8 is an open source LoRaWAN Gateway. It lets you bridge LoRa wireless network to an IP network via
WiFi, Ethernet. The LoRa wireless allows users to send data and reach extremely long ranges at low data-rates.
The LPS8 uses Semtech packet forwarder and fully compatible with LoRaWAN protocol. It includes a SX1308
LoRa concentrator, which provides 10 programmable parallel demodulation paths.
LPS8 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.

2Access LPS8
2.1 Access and Configure the LPS8 via WiFi or Ethernet
The LPS8 is configured as a WiFi Access Point by factory default. You can access and configure the
LPS8 after connecting to its WiFi network, or via its WAN Ethernet port.
WiFi
At the first boot of LPS8, 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 LPS8 has the default IP
10.130.1.1
Ethernet
Alternatively, you can connect your PC to the LPS8 WAN port
via Ethernet cable and obtain an IP address via DHCP. Assume
the IP get from router is 192.168.1.3
Web Interface
Open a browser on the PC and type in the address:
http://10.130.1.1/ (Access via WiFi AP network)
or
http://192.168.1.3 or http://192.168.1.3:8000 (The web port has been changed to 8000
in WAN interface since firmware 5.3.xxx firmware)
You will see the login interface of LPS8 as shown below.
The account details for Web Login are:
User Name: root

3Typical Network Setup
3.1 Overview
The LPS8 supports flexible network set up for different environments. This section describes the
typical network topology can be set in LPS8. The network set up includes:
WAN Port Internet Mode
WiFi Client Mode
WiFi AP Mode
3.2 Use WAN port to access Internet
By default, the LPS8 is set to use the WAN port to connect to an upstream network. When you
connect the LPS8’s WAN port to an upstream router, the LPS8 will get an IP address from the
router and have Internet access via the upstream router. The network status can be checked as
below:
