Can card-inserting routers replace ordinary routers?

In the selection of network devices, card-inserting routers, such as 4G industrial routers and card-inserting industrial routers, often raise people's questions due to their unique connection methods and functional features: Can they be used as ordinary routers?

To answer this question, it is first necessary to understand the working principles and features of card-inserting routers and ordinary routers.

A common router is a core device for network interconnection, operating at the network layer of the OSI reference model. Its main functions are routing selection and data packet forwarding. It exchanges network topology information through routing protocols, dynamically generates routing tables based on the topology, and then forwards data packets from one network to another according to the forwarding table. It is usually connected to the network via wired broadband.

The 4G industrial router in the card-inserting router is fully compatible with 4G/3.5G/3G/2.5G networks and provides users with long-distance wireless data transmission functions by using the public LTE network. It adopts high-performance industrial-grade 32-bit communication processors and industrial-grade wireless modules, with an embedded real-time operating system as the software support platform. Industrial Ethernet routers are mainly used in industrial environments to achieve Ethernet communication connections between industrial devices. They support multiple industrial communication protocols and feature high reliability and stability. The card-inserting industrial router combines the card-inserting network access method with the characteristics of industrial-grade equipment. It usually has a metal casing, is anti-interference and radiation-proof, and can adapt to harsh working environments.

So, can a card-inserting router be used as a regular router? The answer is that it is possible under certain conditions, but there are also some limiting factors.

From a functional perspective, card-inserting routers possess many of the common functions of ordinary routers, such as supporting multiple protocols (TCP/IP, UDP, etc.), having routing and forwarding capabilities, and supporting DHCP, NAT, and other functions. In terms of basic network connection and data transmission, they can meet the needs of ordinary users.

In terms of performance, the communication bandwidth of some card-inserting routers can meet the daily needs of a home or a small office. For instance, some 4G industrial routers have a downlink rate of up to 100Mbps or even higher. For general applications such as web browsing and video viewing, their performance is not much different from that of ordinary routers. However, if a large number of devices are connected simultaneously and high-bandwidth requirements are involved, such as multiple people holding high-definition video conferences or downloading large files at the same time, the card-inserting router may experience lag due to network bandwidth limitations or insufficient processing capacity.

In terms of applicable scenarios, the wireless connection method of card-inserting routers gives them certain advantages. For places that cannot access wired broadband, such as remote areas, temporary office locations or outdoor areas, card-inserting routers can provide network connections through mobile networks by inserting SIM cards, which is something that ordinary routers cannot do. However, in environments with fixed broadband access such as homes or offices, ordinary routers usually offer more stable and high-speed network connections. This is because wired networks are less likely to be interfered with compared to wireless signals, and their transmission rates are also more guaranteed.

In addition, cost is also a factor that needs to be considered. Card-inserting routers usually require payment for mobile network data traffic, and the cost may be relatively high over long-term use. In contrast, ordinary routers only require a fixed broadband fee, which gives them a cost advantage, especially for users with a large amount of network usage.

To sum up, in some cases, the card-inserting router can be used as a regular router, especially in scenarios where there is no wired broadband access or where there is a high demand for network mobility. It can leverage its unique advantages to provide users with network connections. However, in most home and office environments with fixed broadband, ordinary routers remain a more suitable choice because they have more comprehensive advantages in terms of stability, performance and cost. When making a choice, users should decide based on their actual needs, usage scenarios and budget to ensure they can obtain the most suitable network solution for themselves.
