E-Lins Technology shares an Insight on Industrial 4G Routers. They are one of the leading suppliers and manufacturers of 4G routers across the globe.

1. An Insight on Industrial 4G Routers
Industrial router is an IoT wireless communication router that utilizes a public
wireless network to provide users with wireless long-distance data transmission
capabilities. Has been widely used in the M2M industry in the Internet of Things
industry chain, such as smart grid, intelligent transportation, smart home, finance,
mobile POS terminals, supply chain automation, industrial automation, intelligent
building, fire protection, public safety, environmental protection, weather, digital
Medical, remote sensing, agriculture, forestry, water, coal, petrochemical and other
fields.
Introduction
The 4G industrial router is an IoT wireless communication router that uses the public
LTE network to provide users with long-distance wireless data transmission
capabilities. Currently, the mobile LTE network is being initially tested and has not yet
been commercialized in China.
Existing 4G Routers are already compatible with the original 3G networks: WCDMA,
TD-CDMA, EVDO, and HSPA+ with 3.75G network. The actual network application will
be faster than the existing 3G network, and the uplink and downlink speeds will
exponentially increase, which greatly solves the shortcomings of the delays in the
application of wireless networks to large data transmissions, such as the transmission
of high-definition video images. This also solves the drawbacks of the fiber that must
be applied to the large amount of data and high-definition video images in the past,
which will ease the existing wired network.

Parameter Configuration
3.1 Configure the connection
Before configuring the router, you need to connect the router and PC for
configuration through the factory-configured network cable or WIFI. When
connecting with a network cable, one end of the network cable is connected to any
Ethernet interface of the router "Local Network" (hereinafter referred to as LAN
interface), and the other end is connected to the Ethernet interface of the PC. When
connecting with WIFI, the factory default SSID of the router is "FOUR-FAITH" and no
password verification is required.
3.2 Log in to Configuration Page
3.2.1 PC IP Address Settings
3.2.1.1. Obtaining an IP Address Automatically
3.2.1.2. Specifying an IP Address
Set the IP address of the PC to 192.168.1.9 (or the IP address of another 192.168.1

3. network segment). Set the subnet mask to 255.255.255.0 and the default gateway to
192.168.1.1. DNS is set to a locally available DNS server.
3.3 Management and Configuration
3.3.1 Settings
The first page opened by clicking "Settings" is the basic setting. Through this page,
you can follow the prompts to make changes to the basic settings, click the "Save
Settings" button to change but not effective, click the "Apply" button to make the
changes take effect, or click the "Cancel Changes" button to cancel change.
3.3.1.1 Basic Settings
The "WAN Connection Type" setting section describes how to configure the router to
connect to the Internet. You can get this detailed information from your ISP.
WAN Connection Type
From the drop-down menu, select the type of Internet connection your ISP provides
for you. The WAN connection type includes 7 ways: Disabled, Static IP,
Auto-Config-DHCP, PPPOE, PPTP, L2TP, 3G/UMTS/4G/LTE.
3.3.1.2 Dynamic DNS (DDNS)
If the IP address obtained by the router's Internet access is dynamically assigned by
the operator, the IP address obtained by the router at each time may be different. In
this case, a dynamic domain name service can be used. The domain name provider
allows you to register a domain name that always corresponds to the current
dynamic IP address of the router. In this way, the latest Internet IP address of the
router can be accessed by accessing the domain name.
DDNS service: This route supports a variety of DDNS servers, such as: DynDNS,
freedns, Zoneedit, NO-IP, 3322, easyDNS, TZO, DynSIP.
3.3.1.3 MAC address cloning
Some ISPs may require you to register your MAC address. If you do not want to
re-register your MAC address, you can clone the router's MAC address to your
registered MAC address at the ISP.
3.3.1.4 Advanced Routing
On the Advanced Routing page, you can set the operating mode and static routes.
For most users, gateway mode is recommended.
Working mode: Select the correct operating mode. If the router is sharing an Internet
broadband connection, keep the default gateway settings (for most users, we
recommend using gateway mode). If you want to use only the router's routing
capabilities on your network, select the router.
3.3.1.5 VLANs
VLANs function can be divided according to the user's own wishes to different VALN
ports, the system supports VLAN0-VLAN15 this 16 VLAN port, but the time of the
port is only 5, including one WAN port, LAN port 4, according to their own needs
Divided, the LAN port and WAN port cannot be divided into the same VLAN port
3.3.1.6 Network
Tags: Allows you to create a new VLAN interface, a target interface, through the filter
interface, using the defined tag number.

4. Bridge - Create Bridge: Creates a new bridge for use. STP stands for Spanning Tree
Protocol and you can set the priority of the bridge. The lowest number has the
highest priority.
Bridged - Assigned to Bridge: Allows you to specify any valid interface to an already
established bridge.
Current Bridge List: Displays the current bridge list
WAN Port Assignment: Designate the assigned interface of the WAN port. Default:
VLAN1
Multiple DHCPD: Uses multiple DHCPD enabled dnsmasq DHCP services.
