The principle of 4G router:
The wireless 4G module is mainly built into the original router. The user can first use the billing meter (SIM card) to insert the 4G router, and obtain it through the operator’s 4G network dial-up, network WCDMA, TD-SCDMA, data transmission, Internet access, etc.

The router has the WIFI function of sharing the Internet, if the mobile phone, computer or psp has the 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 local area network.

Some manufacturers have wired broadband interfaces that allow normal Internet access without 4G. 4G wireless routers allow broadband connections, and in applications such as monochrome networks, it has become very common to meet or exceed the current network bandwidth of ADSL.

The role of 4G industrial routers

  1. Improve data processing and transmission speed
    With high-performance MIPS core, providing high-capacity memory cache (DDR2-1Gbits), powerful performance and excellent performance to meet the performance requirements of large-scale data transfer applications (such as images and videos)
  2. Network and Communication
    Compared with ordinary routers, the replicated industrial environment also puts forward higher requirements for industrial routers. 4G industrial routers use high-performance industrial-grade 4G wireless modules, provide industrial-grade high security and high-precision components, an extremely wide temperature correction screen from -40 to +85 degrees Celsius, easy to adapt to high temperature and cold working environments, reliable network and no Cybersecurity communication of human 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 backward compatible with 2G/3G and supports td-scdma/wcdma/edge.
  4. Stable WIFI signal
    Dual Wi-Fi antenna signals support 802.11b/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
