Advantages and Disadvantages of 4G Cellular Routers
The 4G cellular router is usually an industrial wireless router device integrating a 3G/4G network, virtual private network, and other technologies. The 4G cellular router relies on a 4G wireless wide area network and Wi-Fi wireless local area network technology to provide uninterrupted access to a variety of network capabilities. With its comprehensive security and wireless service features, it provides users with high-speed and stable data transmission channels. The 4G cellular router is designed to meet the needs of unattended field communication.
As a user, you can communicate with the public network by setting a default gateway for your PC or network device. In effect, the default gateway configured for the network device is the packet exported for the network device. After sending the packet to the router's Ethernet port, the router performs the next task, so the router is an Internet relay.
Advantages of 4G Cellular Router
1. Multiprotocol compatibility: Networks interconnected by single-protocol industrial-grade wireless routers can use the same or different protocols from Layer 1 to Layer 2. Layer 3 uses the same routable protocol, and Layer 4 and above require the same or compatible protocol.
2. Multiple connections: 4G cellular router is capable of complex routing calculations and is suitable for connecting three or more large networks with complex network topologies.
3. Isolation: 4G cellular router can mitigate or reduce external storms because the excellent network isolation source of a 4G cellular router can effectively isolate broadcast storm information.
4. Complex protocol connectivity: Multi-protocol industrial wireless routers can serve as a network interconnection platform using different communication protocols because they can connect to the network through different communication protocols.
5. Stability: 4G cellular router is used to ensure the stability of unattended communication.
Disadvantages of 4G Cellular Router
1. First of all, it's expensive.
2. The initial configuration is extensive and the configuration needs to be professional. Installation and maintenance are difficult.
3. The longer the processing time, the lower the 4G cellular router performance of the entire network.
4. Unlike bridges, routers in industrial networks are protocol-dependent. For network connectivity, each advanced protocol must be configured separately, and a 4G cellular router must be provided for each protocol, with a separate protocol for each protocol.
5. The 4G cellular router does not support non-routing protocols, so when multiple networks are interconnected, the protocols used by the connected networks are limited.
The application of 4G cellular router products covers smart cities, integrated pipe galleries, smart manufacturing, rail transit, smart power, coal, and petrochemical industries. Among them, a 5g cellular router is an outdoor communication device realized through a 5G network. The speed of a 5G cellular router is 20 times that of a 4G cellular router, and the price is proportional to the speed. At present, the market price of a 5G cellular router is three times or even higher than that of a 4G cellular router.
