· Network layer: The network layer is the third layer of the OSI model that deals with maintaining and handling devices requests. This layer is responsible for receiving the data from the transport layer and transferring it to the link layer. It translates the logical address into a physical address. In this step, the layer validates data integrity by applying different checks such as CRC, frame length, parity bit, and others.
· Processing: In this step, the router starts processing of the IP layer. Each data packet has a different IP address that the router uses for the next hop. This determines what route the data packet will take to reach the link layer.
· Link layer: The data link layer is responsible for transferring data and removing possible errors. This layer uses a node-to-node method for transferring the data packets. There can be some errors in the previous layers, the link layers detect and fix them. The Link layer has two different types of sub-layers media access control (MAC) and logical link control (LLC). These sub-layers take care of multiplexing for the devices and provide flow over a network by defining protocols.
An industrial 4G LTE modem router finds an optimal path for the data packets for faster transmission of data. The key element of these routers is that they detect the right path by using an algorithm. There are different transportation paths, the critical task is to maintain the level of performance. Industrial 4G LTE modem routers manage the access control, network address translation, queuing priority, and other processes.
What is an industrial 4G LTE modem router?
An industrial router is a shock-resistant device that can and internal components that can work in extreme climate conditions. Industrial 4G LTE modem router has a stable connectivity and security feature for transmitting data. This device acts as a backbone for applications in various industries such as outdoor environments, mining, oil, gas, agriculture, and more.
What is the benefit of using industrial 4G LTE modem router?
· Network sharing: With an industrial 4G LTE modem router, you can connect to multiple devices and share data. Industrial routers can connect to both wired and wireless devices such as PLC/ATM/POS, sensors, actuators, Cloud servers, and other devices.
· No limitation of WAN network: Industrial 4G LTE modem routers work with a cellular network and can easily connect to any network that covers 4G service. The routers we normally use does not provide an interface with different devices and only has RJ45 and RJ11 port.
· High performance: By using an industrial 4G LTE modem router you get a 32-bit processor supported by a real-time operating system. The router has a module that has the capability of transmitting the data over the server.
· Failover connectivity: An industrial 4G LTE modem router has an option of DSL/FTTH Ethernet that allows the network to seamlessly transfer data in connection failure. This is the best advantage a business can get from an industrial router. Most 4G LTE modem routers have dual sim ports which an organization can use if one port stops working.
How to choose the right industrial 4G LTE modem router?
· Environmental conditions: An industrial vp n router has the specialty of withstanding in harsh temperatures. Whether it is too cold or too hot, the router will seamlessly transfer data between devices.
· DIN Rail mounting: The DIN-Rail mounting in routers makes it easy for the device to connect to Ethernet cables. A Din rail mounted router establishes a stable connection between the networks until all data packets reach the destination. This type of router is the perfect way to organize data in a single space. It helps in ensuring that there is no data loss.
· Power supply: Most industrial routers support DC power supply. DC power supply works more efficiently than AC power and can provide higher power over long distances. The advantage of using DC power in industrial routers is that they provide maximum power flexibility.
· Management system: For managing the content of the industrial router, there must be secure, reliable, and flexible router management software. A router management system must have a license that ensures secure communication of the servers. The system should support firmware and different configurations to store data. Other factors include generation of data streams, updating the data, on-demand diagnostics for management, and simple device setup.
· Integration: Industrial 4G LTE modem routers not only connect to the internet but also need access to the cloud environment. It helps in the establishment of different IP address ranges. With the integration of an industrial router with Cloud, it can advertise subnet routes and custom prefixes on its BGP sessions. The benefit of Cloud technology is that it provides best-of-breed cloud resources, optimizes cloud data center locations, and reduces security risk.
