Difference between 4G Lte Modem and 4G Lte Router in Power Charging Pile

With the rapid development of Internet of Things technology,4G Lte Modem (data transmission unit) and 4G Lte Router are more and more widely used in the field of charging piles.Although these two devices have some similarities in function, there are obvious differences in the power charging pile.In this paper, 4G Lte Modem and 4G Lte are analyzed from the aspects of technical principles, application scenarios and performance requirements.The difference of Router in the charging pile is described in detail.

I. Technical principle

4G Lte Modem: 4G Lte Modem is a data transmission device based on 4G network.It converts the data of serial port, Ethernet and other interfaces into IP packets and transmits them through 4G network.4G Lte Modem has high-speed and stable data transmission capability, which is suitable for remote monitoring, data acquisition and other scenarios.In the field of charging piles, 4G Lte Modem is mainly used to realize data transmission between charging piles and remote servers.O as to carry out real-time monitoring and remote control on the charging pile.

4G Lte Router: The 4G Lte Router is a router device designed specifically for industrial environments.It has powerful data processing ability and rich interface types.4G Lte Router not only supports wired and wireless network connection, but also realizes multiple protocol conversion and data processing functions.In the field of charging piles, 4G Lte Router is mainly used to build the local area network of charging piles.It realizes the interconnection between charging piles and peripheral equipment (such as charging pile controller, payment terminal, etc.).And data transmission between the charging pile and the remote server.

II. Application Scenario

4G Lte Modem: Since the 4G Lte Modem mainly relies on the 4G network for data transmission,Therefore, it is more suitable for charging pile scenarios with wide distribution and large number.For example, in urban public transport, highway service areas and other scenarios, the distribution of charging piles is relatively scattered.Using 4G Lte Modem, remote monitoring and control can be easily realized.

4G Lte Router: The application of 4G Lte Router in the field of charging piles mainly focuses on building a local network environment.In the charging pile site, 4G Lte Router can realize the interconnection between the charging pile and the peripheral equipment.And that data transmission efficiency and stability are improve. In addition, the 4G Lte Router supports multiple protocol conversion and data processing functions.It can better meet the diversified needs of charging pile sites.

III. Performance requirements

4G Lte Modem: Since the 4G Lte Modem relies on the 4G network for data transmission,Therefore, its performance requirements mainly include network stability, data transmission rate and coverage.In the field of charging piles, 4G Lte Modem needs to have high network stability and data transmission rate.To ensure real-time communication between the charging point and the remote server.

4G Lte Router: The application of 4G Lte Router in the field of charging piles focuses more on LAN construction and data processing capabilities.Therefore, its performance requirements mainly include network interface richness, protocol conversion capability, data processing capability and so on.In the charging pile site, the 4G Lte Router needs to have powerful data processing capabilities and rich interface types.To meet the interconnection needs of charging piles and peripheral equipment.

There are obvious differences between 4G Lte Modem and 4G Lte Router in terms of power charging piles.4G Lte Modem mainly relies on 4G network for remote data transmission and monitoring.It is suitable for charging pile scenes with wide distribution and large quantity;The 4G Lte Router pays more attention to building the LAN environment of the charging pile site.Realize the interconnection and data processing function between the charging pile and the peripheral equipment.In practical application, appropriate equipment should be selected according to specific needs and scenarios to help the construction and operation of charging piles.
