How do industrial 4G LTE modem routers route data?

November 11, 2021

Routers use different routes to forward data packets from one network to another. A router uses NICs to connect and configure multiple networks. An industrial 4G LTE modem router figures out the fastest paths to transmit the data. If the router gets two path options to transfer data, it will choose the path with the lowest metric. Every router maintains a routing table that consists of a list of possible paths. Whenever a router gets a data packet, it searches for the most convenient path from the table. The industrial 4G LTE modem routers also have the option of managing the routes. The user can change passcodes, encrypt the network, create custom forwarding rules, and much more.

What are the features that let an industrial 4G LTE modem router operate in a harsh environment?

· High availability: Industrial 4G LTE modem routers need to have a high level of availability because in industries there are no options for internet access. These routers use major network technologies to ensure a stable connection. The wireless technologies include LTE, UMTS, GSM, and many others. All industrial 4G LTE modem routers have multiple SIM slots that help them to connect to the WAN network. Industrial 4G LTE modem routers use multi-technology to avid network redundancy that leads to high availability.

· Compact and Ruggedized: The size of an industrial 4G LTE modem router is very important. As it serves industries, there is less space to fix and use the router. For example, using an industrial 4G LTE modem router in the mining industry. If you deploy the router on a piece of mining equipment, a compact one will fit perfectly. An industrial 4G LTE modem router should also be shock-resistant to stand up in harsh environments. A router needs to survive through harsh conditions without cooling appliances because such resources are not always available.

· Bulletproof Software: An industrial 4G LTE modem router must be ultra-reliable. Routers are small computers that have an operating system and router software. Most routers use proven and mature technology like Linux. Linux is an open-source operating system that can easily manage routing software.

· Extended functionality: A user wants an industrial 4G LTE modem router that can perform multiple functions. As in industrial work, we don't have enough space to attach different devices. An industrial 4G LTE modem router can provide location services that have built-in, various network services including DHCP, DNS, NTP, SNMP.

· Quality of Service: Users expect the best results from industrial 4G LTE modem routers. These routers need to perform mission-critical communications which are possible with good quality of service (QoS) functionality. Industrial 4G LTE modem routers use dedicated bearers to create a tunnel for data transmission. By using high-quality services, industrial routers can deliver guaranteed bit rates for critical applications.

How to select a good industrial 4G LTE modem router?

· Brand: A brand represents quality. The technology industry is the only industry that changed a lot in the past few years. From telephones to smartphones, PCs to laptops, and many other things. As there was advancement in technology, many new companies started developing technological products such as smart home devices, routers, M2M devices, etc. It is important to learn about the brand before buying the product. In the market, several companies will guarantee that they develop the best industrial 4G LTE modem routers. The customer should also know how to differentiate between a good and poor-quality industrial router. By communicating with other customers, reading reviews, a customer can know if they should buy the industrial router from the company or not.

· Security: In all of the IoT devices, security is a major concern of customers. It relates to the ethics and privacy of the company. An industrial 4G LTE modem router uses an encryption method to prevent unauthorized users from accessing the data. But if a professional hacker manages to enter the network, he can try different encryption techniques to decode the data. So, an industrial 4G LTE modem router needs to have a good security system, it will prevent hackers from accessing important information.

· Stability: The core factor of an industrial 4G LTE modem router is its stability. An industrial router has a 32-bit processor that improves the performance level up to 3 times. Also, shielding electromagnetic interference, radiation protection materials protect the device in the harsh environment of industrial projects. The router uses a TCP/IP protocol for excellent network performance that reduces the probability of dropping data. Industrial 4G LTE modem router has a larger memory to store the data sent by users.
