What are 4G industrial Routers?

The 4G industrial router is simply based on the common router, providing the industrial version design and 4G network access to high-speed networking equipment. It usually has WIFI wireless LAN function, supports 4G LTE network system, and is compatible with 2G/3G network. And according to the priority of 4g-> 3g-> 2G, the network is automatically selected.

How 4G industrial routers work

The principle of 4G industrial router is also very simple. Users can only insert a SIM card into the 4G industrial router, and the dial-up network through 4G network can realize high-speed Internet access and remote data exchange transmission. The WIFI function of 4G industrial routers can also realize network sharing and data transmission within short distance or local area network. From the point of view of using method alone, the idiotic operation of 4G industrial router is favored by the market public.

Features of 4G industrial routers

4G industrial routers tend to be outdoor and practical. They are mainly used for industrial control projects, so they have high requirements for environmental adaptation, safety protection and appearance protection.

Industrial design of 4G industrial router

Industrial 4G industrial networking module and high precision components are adopted to adapt to different harsh outdoor environments such as high temperature and severe cold.

The industrial high performance embedded structure and industrial high performance 32-bit ARM communication processor are adopted to ensure stable data transmission.

Industrial installation buckle design, installed on the guide rail, can also be installed with any combination of hanging ear;

Sheet metal shell is used to increase the safety isolation coefficient. It is more suitable for on-site operation of industrial control projects.

4G industrial router security protection

The built-in electronic dog design ensures the system is safe and stable and never goes down.

Circuit protection includes power anti-reverse connection, ESD electrostatic protection, anti-surge protection, stable and reliable 24-hour operation.

Firewall protection, greatly improve the security of the internal network, reduce the risk.

The powerful function of 4G industrial router

-Support operators' dedicated network APN and virtual private network VPN (including VPN client and VPN sever). VPN supports PPTP and L2TP protocols.

-Support QOS management services, set device priority and device and application broadband restrictions, and make it easier to manage various networking servers.

-Support DHCP server and DHCP client, DHCP binding MAC address, real-time display of data transmission rate and other functions;

-Support TCP/IP, UDP, FTP, HTTP and other network protocols, easy to use, flexible, a variety of work mode choice;

-Convenient system configuration and maintenance interfaces (including local and remote WEB and CLI modes);

-Support various WAN connection modes, including static IP, DHCP, L2TP, PPTP, PPPOE, 2G/3G/4G;

-Support remote management, SSHD, HTTPS and other functions;

-Support local and remote online upgrades, import and export profiles · support NTP, built-in RTC;

-Support various DDNS at home and abroad;

-Support MAC address cloning, PPPoE server;

-Support a variety of up - and - down trigger modes, including SMS, telephone ringing, serial data, network data trigger up - down mode.

Application range of 4G industrial routers

Currently widely used in the industries of M2M in IoT industry chain, such as industrial control network, the smart grid, personal health care, intelligent transportation, smart home, financial, mobile POS terminals, supply chain automation, industrial automation, intelligent building, fire control, public security, environmental protection, meteorology, digital medical treatment, remote sensing survey, agriculture, forestry, water, coal, petrochemical and other fields.

Influence factors of the transmission range

In practical application, the transmission range of industrial wireless routers is affected by many factors.

First of all, many people don't have a clear understanding of the transmission range of industrial wireless 4g routers. Generally, the wireless network signals of industrial wireless routers are marked in the manual.

However, this is not the case. The theoretical data are obtained in an ideal test environment. The specific influencing factors are as follows:

Factor 1: Affected by the router's own transmitting power. This is the decisive factor affecting the transmission range of industrial wireless routers. The higher the power, the wider the transmission range, but according to relevant national regulations, the maximum transmission power shall not exceed 100MW, i.e., 20dBm (2.4 GHz frequency band). Because the higher the power, the greater the radiation, this is harmful to the human body.

Factor 2: Affected by terrain and obstacles. The practical application environment of routers is complex and changeable, so it is hard to find the wireless signal range value in the test environment, which is mainly affected by the environment and obstacles and interferes with the wireless network. Among them, the barrier walls with glass and metal have the biggest influence on the signal of industrial wireless routers.

Factor 3: High gain antenna can increase the stable receiving distance. Gain is to increase the power density ratio of the signal generated at the same point in space between the actual antenna and the ideal radiation unit and enhance the transmission range when the transmission power is certain.

Factor 4: Weather. Industrial wireless routers are different from ordinary routers in home. They are mostly used in outdoor environments, which determines that they are greatly affected by weather. The harsh outdoor environment also puts forward high requirements for the anti-oxidation and high protection of the router chip.

When users choose industrial wireless routers, they can choose products with appropriate power and gain antennas according to their own needs and use them in open areas as far as possible, which can maximize the transmission range of routers.
