What are the transmissions benefits and security elements of 4g industrial routers?
Transparent transmission, simply put, is "fully transparent transmission". To ensure the quality and quantity of the premise, the data information will be transmitted to the destination connection point, and do not do everything to resolve the data information. Transparent transmission is generally used to load remote control of serial communication data information. For example, the bus station are to brush the identity information to enter, but the identity information database query is unlikely to be placed near every train station. This time you can choose 4g industrial router to collect and transmit the data to the bus station's auditing service platform, and carry out comparison with the identity document goods
A. What are the benefits of 4G industrial router's transmissions
1, real and effective: the real and effective data will be transmitted to the destination intact, and then according to the original data for distribution processing. The transmitted data is not processed in any way to ensure that the field data is transmitted to the destination node without any deviation, thus ensuring that the data is real and valid.
2、Simple and convenient: not bound by any protocol, all can carry out the original data transmission. No matter what the transmitted data is, it can reach the destination node behind.
Second, the security factor of 4G industrial router
The security of 4G industrial router is like a guard to protect the normal work of the heart, to ensure that the industrial router can be used normally through the transmission. For example: 4G industrial router using high-performance core, metal shell protection level. Power supply supports terminal power supply, voltage range 9~16V, providing a variety of protection, support anti-reverse connection, anti-surge, anti-static protection, in the industrial control site applications with ease.
C. Application characteristics of industrial grade 4G router
(A) Advantages.
1、Because industrial routers have the ability to perform complex routing calculations, they can reasonably and intelligently select better paths, so they are suitable for connecting more than 2 large-scale and networks with complex network topologies
2、Industrial routers can isolate broadcast storm information within the source network, which can reduce and control the impact of broadcast storms
3、Multi-protocol industrial wireless router can connect networks using different communication protocols, so it can be used as a platform for interconnection of networks using different communication protocols
4, single-protocol industrial wireless router interconnection network, in layer 1-2 can use the same or different protocols; in layer 3 use the same routable protocols: while layer 4 and above require the use of the same or compatible protocols
5, the use of industrial 4G routers can isolate unwanted communications, so that the interconnected network to maintain their independent management control range, to improve the security performance of the network. Therefore, industrial 4G routers are often used as firewalls to restrict access to external networks (Internet) and external networks inside the LAN, playing the role of network shielding
6, the router can also be used as a bridge, in order to deal with not "routable" protocol
7、The network segmentation function of the network router can improve the performance of the network and reduce the burden on the host
8, can provide reliable transmission, priority services, and industrial LTE routers do not need to communicate with each other to maintain the connection between the networks
(II) Disadvantages
1, there are many initial configurations when installing the industrial LTE router, therefore, its installation and maintenance is more difficult
2, different from the bridge, industrial router is related to the protocol, inter-network connection of each high-level protocol to be configured separately, to provide a separate protocol for each protocol industrial router
3, using more time for processing, resulting in industrial router network transmission performance degradation
4、Higher price
5、Industrial all-network router does not support non-routing protocols, so when interconnecting multiple networks, there are restrictions on the protocols used by the connected networks
