The Role of Cellular Routers

PublishTime： 2023-08-17 Article Source：usr News

With the advent of the Internet of Things era, Cellular Router plays a vital role in the industry. It is often used in the industry with the application of 4G LTE modem data transmission and PLC remote gateway control to make IIOT more unmanned. It liberates the manpower of engineers who travel back and forth in different places and the labor force of manual detection at all times, and realizes the industrialization of intelligent unmanned in a real sense.

The cellular router is a high-speed industrial Internet of Things router, fully compatible with 4G/3.5G/3G/2.5G networks, with VPN links, industrial protection, and wide temperature setting correction, which can simply form a high-speed and stable wireless transmission network using the public LTE network.

The cellular router uses a high-performance industrial 32-bit communication processor and an industrial wireless module and uses an embedded real-time operating system as a software support platform, including RS232 (or RS485/RS422), Ethernet LAN, Ethernet WAN, and Wi-Fi.

The principle of the cellular router

The wireless 4G module is mainly built into the original router. Users can first use the meter (SIM card) to insert into the 4G router, which can be obtained through the operator's 4G network dialing, network WCDMA, TD-SCDMA, data transmission, Internet access, and so on. The router has the WIFI function to share the Internet. If the mobile phone, computer or PSP has a wireless card or wifi function, you can access the Internet through the 4G wireless router, which is very useful for sharing the 3G wireless network in the wireless LAN. Some manufacturers have wired broadband interfaces that allow normal Internet access without 4G.4G wireless routers allow broadband connectivity, and in applications such as monochrome networks, it is becoming very common to meet or exceed the current network bandwidth of ADSL.

The role of the cellular router

1. Improve data processing and transmission speed

High-capacity memory cache (DDR2-1Gbits) with high-performance MIPS core, powerful performance, and excellent performance to meet the performance requirements of large data transfer applications such as image and video

2. Network and communication

Compared with ordinary routers, the complex industrial environment also puts forward higher requirements for cellular routers. The cellular router uses high-performance industrial-grade 4G wireless modules to provide industrial-grade high-security and high-precision components, an extremely wide temperature correction screen of -40 to + 85 degrees Celsius, easy adaptation to high temperature and cold working environments, reliable network and network security communication for unmanned systems.

3. 2/3/4G signal self-switching

The dual 4G antenna signal is more stable. In addition to the two LTE standards of FDD-LTE/TD-LTE, it is also downward compatible with 2G/3G and supports TD-SCDMA/WCDMA/edge.

4. Stable WIFI signal

Dual Wi-Fi antenna signals support 802.11 B/G/n and up to 24 wireless STA connections with automatic and manual channel selection. In addition, the WIFI signal supports WPA/WPA2, WEP, and other encryption methods, and the WIFI signal is safe and stable.
