Industrial 4G LTE Modem Router

An industrial 4G LTE modem router connects multiple devices and translates the data between them. There are three main aspects of a router generating a routing table, finding the correct route, and data forwarding. The industrial modem router receives the data pack and address to forward the data packet. When the data packet comes to the industrial router, it invokes the link-layer functional module to interpret further processing. The step validates the data and creates a frame length check. After this, the switch looks for the IP address for the next hop. The next-hop address is then noted in the routing table and is encapsulated after reaching the destination.

What advantages can a user avail from an industrial 4G LTE modem router?

• Sharing information: With a switch, the user gets a 4G LTE connection to work with. The devices can be connected to multiple hardware peripherals such as sensors, actuators, monitors, and more. This allows for creating a virtual office and processing the data from anywhere.
• Pop-up 4G: For industries in rural areas, a switch can work as a conventional ADSL, in such areas. Further improvements in the routing function can be done by adding.
• Remote service: Switches are built for extreme environments and can survive without affecting the transmission quality. An industrial router is an ideal solution for temporary locations and can fix the problem of broadband solutions.

• Building sites: It can be a costly investment to install a wiring system to access the internet. There is no guarantee that internet access will work efficiently on industrial sites. With a modem, a virtual tower of internet connection can be built. The industrial 4G LTE modem router can keep running in fail-over connectivity. It uses a DSL/FTTH WAN option that is ideal for the prevention of downtime.

What are the vulnerabilities of an industrial 4G LTE modem router?

Routers are a critical component of any infrastructure as they record, transmit, and receive data. During the operation, an industrial router holds the responsibility to manage the connection between all connected devices. It acts as a gateway to network and responds to clients’ requests. But there are several vulnerabilities of the router. If a router is left unsecured, it can cause a problem. The Internet is full of hackers, they are always waiting for a chance to get into the network and access the information. The hacker can steal consumer and utility data, shut down meters, change billing amounts, or lead to denial of service.

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

• Compact and ruggedized: An modem must be compact. As this needs to be used in industries, there is not much space available to set up the router. For example, if the router is being used in the mining industry. A compact 4G LTE router can be easily placed on any machinery. For an industrial 4G LTE router, it must be ruggedized to survive in a harsh climate.
• High availability: Switches should have high availability. These routers serve the purpose of providing an internet connection in areas with no network access. If the routers do not have high availability and stop working during the operation, the industry can lose important information. The switch should have a multi-sim feature. It enables the user to stay connected to the WAN network and configure another network if one is not working.

• Bulletproof software: Routers are a type of computer that works with an operating system and application software. These routers must be extra-reliable. The data used in industries is critical and they cannot afford to lose the information due to system error.
• Quality of service: Every user expects high-quality results from any device he is using. A modem must guarantee excellent performance. For instance, if a router is being used in critical communications, the data must be encrypted and protected. The modem router must be able to avoid data breaches or corruption attacks during the transmission phase.
• Extended functionality: Switch must-have GPS/GNSS/GLONASS capabilities. Some routers have built-in web servers, VPN servers, and RADIUS servers. This allows the user to connect his I/O or other devices in a WAN network.
• Security: For all technological devices, security is one of the major features. Without security features, a device is not safe from external or internal attacks. The switch uses different protocols such as DHCP, DNS, NTP, SNMP, and more.
