The 4G LTE router and the 4G LTE modem are both used for wireless network data transmission of industrial equipment.The 4G LTE modem and the 4G LTE router are two common 4G network devices. There are some differences in their functions and applications.Specifically, it can be reflected in the appearance, operation methods and use environment.
The hardware design of 4G LTE router usually reserves network ports to facilitate wireless networking of network port devices.The network port device accesses the center to complete the transmission process of network data.Generally speaking, the 4G LTE router of PUSR will provide users with interfaces such as WAN/LAN ports or WAN/LAN free switching.It is convenient for users to match freely.However, from the appearance, the 4G LTE modem generally only provides a serial interface for networking, which is used for two-way transparent transmission of TTL and data.
What if you need both a network port and a serial port in an industrial project?Never mind, PUSR's 4G LTE modem USR, G781, can solve this problem perfectly.The 4G LTE modem G781 has its own routing function, which can be quickly connected to the Internet for transmission.
4G LTE modems are generally small, lightweight, and sometimes can be integrated directly into other devices.O as to realize real-time data transmission and monitoring functions.It tends to focus on data transfer and communication and lacks some of the advanced features and interfaces of the 4G LTE router.
The 4G LTE router generally has more powerful hardware performance and protection capabilities, and supports more interfaces and protocols.It has higher signal coverage and network stability.It is usually designed to work stably in harsh environments for a long time, which can meet the requirements of industrial applications.More demanding than cellular wireless router.
The 4G LTE modem is mainly used for data transmission and communication connection,It connects sensors, instruments, equipment and other non-network devices through serial ports or IO ports.The data is transmitted to the server or cloud platform through the 4G network to realize remote monitoring, data acquisition, remote control and other functions.
The 4G LTE router is generally a device that integrates routing, switching, firewall, and other functions, in addition to providing 4G network connectivity.It also has the ability of data transmission, network management and security protection.It can handle the network connection of multiple terminal devices and provide functions such as distribution, data isolation and remote access of the local network.
Lte 4G router usually supports VPN/APN function, with good encrypted transmission effect;This is very appropriate for video surveillance, oil well data monitoring, street lamp monitoring and other scenarios.Lte 4G router, which supports Wi-Fi function, can be used with public transport to create a smart city atmosphere.Comparatively speaking, 4G LTE modem is more dispersed in the transmission distance of field terminals.Therefore, it is more suitable for charging pile control, environmental monitoring and other fields.
Lte 4G router supports Ethernet/bus communication protocol conversion, and the IP address is set in the terminal as the gateway in advance.The 4G LTE modem, on the other hand, is primarily used for dial-up Internet access, not as a true gateway.For example, the 4G LTE modem can be used as a new network device after the access terminal completes dialing.
4G LTE modem is mainly used in remote monitoring, Internet of things, environmental monitoring and other fields.Data acquisition and remote management of non-network equipment are realized through 4G network.For example, it is used in agricultural monitoring, smart home, industrial automation and other scenarios.
Lte 4gThe router is suitable for industrial control, intelligent transportation, energy monitoring, etc., which require high network connection, data security and high reliabilityField. It can provide stable network connection and data transmission, and realize real-time monitoring, data backup, remote maintenance and other functions.
There are differences in functions and application scenarios between 4G LTE modem and Lte 4G router.The 4G LTE modem is mainly used for data transmission and communication connection, and is applicable to the fields of remote monitoring and the Internet of things;Lte 4G router is a device that integrates routing, switching, firewall and other functions.It is suitable for industrial control and high reliability network communication scenarios.
4G modem is a kind of wireless communication device, which can realize the function of converting wired transmission protocol into wireless 4G network for transmission.Compared with routers, 4G modems are more focused on data transmission and remote control.It is widely used in industrial automation, intelligent transportation and other industries.However, a 4G modem can also be used as a simple Lte 4G router in some situations.
First of all, it should be clear that although there is some overlap between 4G modem and Lte 4G router,But their main functions are different.Lte 4G modem is mainly used to convert wired interface into wireless communication and transmit data to cloud or other systems through 4G network.Lte 4G router, on the other hand, connects multiple devices and provides functions such as LAN internal communication and Internet connection.Therefore, in a very simple situation, 4G modem can replace the function of Lte 4G router, but in a complex network environment,Lte 4G router is still irreplaceable.
Second, there are some prerequisites for using a 4G modem as an Lte 4G router.First of all, 4G modem must support wireless LAN function, namely WIFI function.Second, there needs to be enough wired interfaces to connect other devices.Finally, there needs to be enough performance to support the traffic and operation of the entire network.
When the above conditions are met, the 4G modem can be used as an Lte 4G router through the following steps:
To use a 4G modem as an Lte 4G router, the first step is to set up the WIFI feature.Usually, the 4G modem does not enable the WIFI function by default, so you need to enter the device management interface to set it.The specific operation mode may vary with different manufacturers and models, and it shall be set according to the instructions during operation.
When connecting other devices, you can use the wired interface of the 4G modem or the built-in WIFI module.If you use a wired interface, you need to plug the network cable of other devices into the wired interface of the 4G modem, and then set it up accordingly.If you use WIFI to connect to other devices, you need to search for the WIFI signal of 4G modem on other devices.Enter the password to complete the connection. When connecting to other devices, pay attention to whether the maximum number of connections for 4G modem is exceeded.
After connecting other devices, you need to enter the router LTE 4G devices setting interface of the 4G modem.Perform IP address allocation, port mapping and other related settings. These settings are basically the same as those of the Cellular Wireless Router,However, the specific operation mode may vary according to different manufacturers and models.When setting up the Lte 4G router, please ensure that it will not cause security risks to the network or affect the normal use of other devices.
The 4G modem can be used as a simple Lte 4G router, but it is mainly used for data transmission and remote control.When choosing equipment, you should choose according to the actual needs, and ensure that the equipment can meet your own needs and safety requirements.At the same time, in the process of using, we need to pay attention to the stability and safety of the equipment, and abide by relevant regulations and laws and regulations.
