What is 4G Router?The 4G Router is a high-speed industrial Internet of Things router, which is fully compatible with 4G/3.5G/3G networks, supports VPN links, industrial-grade protection, and a wide-temperature design. It can easily build a high-speed and stable wireless transmission network. Users provide wireless long-distance data transmission functions.
Transparent transmission is a characteristic of 4G routers, and in layman's terms it is "transparent transmission". It is necessary to transmit the data to the destination node under the premise of ensuring the quality and do not do any processing on the data. Transparent transmission is generally used to read remote serial port data. For example, train stations need to swipe ID card information to enter, but the ID card information database cannot be placed near every train station. At this time, 4G industrial routers can be used to collect and transmit data to the proofreading platform of the train station for comparison with identity verification.
Ⅰ.What's the principle of 4G Router?
The wireless 4G module is mainly built into the original router. The user can first use the charging meter (SIM card) to insert into a 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 a WIFI function for sharing the Internet. If your mobile phone, computer, or PSP has a wireless card or wifi function, you can access the Internet through a 4G wireless router, which is very useful for sharing 3G wireless networks in a wireless LAN. Some manufacturers have wired broadband interfaces and can access the Internet normally without 4G. 4G wireless routers allow broadband connections, and in applications such as monochrome networks, it has become very common to reach or exceed the current network bandwidth of ADSL.
Ⅱ.What's the role of 4G Router?
1. Improve data processing and transmission speed
Use high-performance MIPS core to provide high-capacity memory cache (DDR2-1Gbits), powerful performance, and excellent performance to meet the performance requirements of large data transmission applications (such as images and videos)
2. Network and communication
Compared with ordinary routers, the replicated industrial environment also puts forward higher requirements on industrial routers. 4G industrial routers use high-performance industrial-grade 4G wireless modules, provide industrial-grade high-security and high-precision components, extremely wide temperature correction screens of -40 to +85 degrees Celsius, easy to adapt to high temperature and cold working environments, reliable networks, and wireless Network security communication of human system.
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, which can automatically and manually select channels. In addition, the WIFI signal supports WPA/WPA2, WEP, and other encryption methods, and the WIFI signal is safe and stable.
Ⅲ. Factor one that affects the coverage of 4G Router: environment
In an open environment, the signal coverage of 4G industrial routers is bound to be wider. If there is interference from water, signal interference sources, metal objects, or walls in the transmission environment, it will inevitably affect the signal of 4G industrial routers. The result of the influence depends on how much the interfering substance affects the signal. For example, the thickness of the wall in the transmission medium or the wall material has different effects on the signal coverage.
Ⅳ. Factor two that affects the coverage of 4G Router: antenna
The longer the antenna, the stronger and wider the signal, or the number of antennas is also an important factor affecting the coverage of WIFI signals. Otherwise, you will not see 4G industrial routers with 3 or 5 antennas on the market. At the same time, the antenna quality of the 4G industrial router is also critical. The high-quality 3dBi antenna can achieve high-gain signals, and the wifi distance can reach more than 100 meters.
