Advantages and shortcomings for dual sim 4g router

Industrial dual sim 4g routers are generally used for industrial purposes, then what advantages and shortcomings they have?

Industrial dual sim 4g router do not need wired WAN, and can move at any time, so they can play the role for wireless network connection. Inserting a SIM card can realize remote data transmission, simplify construction and reduce operation and maintenance management costs.

Advantages:

1. Because industrial routers have the ability to perform complex routing calculations and can select the best path rationally and intelligently, they are suitable for connecting more than two large-scale networks with complex network topologies.
2. Industrial-grade routers can isolate broadcast storm information in the source network, thereby reducing and suppressing the impact of broadcast storms.
3. The multi-protocol industrial wireless router can connect to networks that use different communication protocols, so it can be used as a network interconnection platform that uses different communication protocols.
4. For networks interconnected by single-protocol industrial-grade wireless routers, the same or different protocols can be used at layers 1-2; the same routable protocol is used at layer 3: the same or compatible protocols are required at layer 4 and above.
5. The use of industrial 4G routers can isolate unnecessary communications, so that the interconnected networks maintain their own independent management and control ranges, and improve the security performance of the network. Therefore, industrial-grade 4G routers are often used as firewalls to restrict the internal and external networks (Internet) of the local area network and the access of external networks to the internal area of ​​the local area network, and play a role of network shielding.
6. The entire network router can also be used as a network bridge to deal with non-routable protocols.
7. The network segmentation function of the router can improve the performance of the network and reduce the burden on the host.
8. It can provide reliable transmission and priority service, and industrial LTE routers do not need to maintain permanent connections between networks that communicate with each other.

Shortcomings:

1. There are many initial configurations when installing an industrial-grade LTE router, so its installation and maintenance are difficult.
2. Unlike network bridges, industrial network-wide routers are protocol-related. Each high-level protocol in the network connection must be configured separately, and an industrial-grade network-wide router with a separate protocol must be provided for each protocol.
3. Use more time for processing, resulting in a decline in the network transmission performance of the entire network of industrial routers.
4. The price is higher.
5. Industrial routers do not support non-routing protocols, so when interconnecting multiple networks, there are restrictions on the protocols used by the connected networks.

E-Lins has varies model of 4g/5g router to suit for many industrial areas. Small size router for tight space like H685 4g router and H685f 5g router. It’s single sim and supporting many function, GPS/WiFi/Serial port. Dual sim model we have popular model H900 4g and H900f 5g router. Kindly contact us if you have interest.
