Ⅰ.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.

 

Ⅱ.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.

 

Ⅲ.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.

 

Ⅳ.What's the advantage and disadvantage of 4G Router?

Advantages of industrial 4G Router

1. Industrial-grade routers can isolate broadcast storm information in the source network, thereby reducing and suppressing the impact of broadcast storms.

2. The multi-protocol industrial wireless router can be connected to networks that use different communication protocols, so it can be used as a network interconnection platform that uses different communication protocols.

3. The entire network router can also be used as a network bridge to deal with non-routable protocols.

4. The network segmentation function of the full Netcom router can improve the performance of the network and reduce the burden on the host.

5. It can provide reliable transmission and priority service, and industrial LTE routers do not need to maintain permanent connections between networks that communicate with each other.

 

Disadvantages of industrial 4G Router

1. There are many initial configurations when installing an industrial-grade LTE router, so its installation and maintenance are difficult.

2. Unlike network bridges, industrial network-wide routers are protocol-related. Each high-level protocol in the network connection must be configured separately, and an industrial-grade network-wide router with a separate protocol must be provided for each protocol.

3. Use more time for processing, resulting in a decline in the network transmission performance of the entire network of industrial routers.

4. The price is higher.

 

Ⅴ.What are the factors that affect the coverage of the 4G Router?

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.

 

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.

 

Ⅵ.How do I find the best 4G Router?

1. Select from function.

The role of 4G industrial router is comparable to the role of application areas in that both are based on the selection of 4G routers that are suitable for the major parameters according to project regulations. If a certain role is required, you can also choose to tailor the product.

 

2. Select from the application category.

The home-installed wireless router is no longer considered now that the 4G industrial router model is the option. The industrial router's application field is determined by the project's requirements, and it is sufficient to select a 4G industrial router with matching major parameter index values. For example, in the winter, the temperature for outdoor industrial production projects in cold places is around minus 20°C-40°C. All routine operations must be carried out at that temperature, which necessitates the use of 4G industrial routers with a larger temperature range.

If the intelligent public transportation system software uses a 4G industrial production wired router, and the data information transfer rate and socket needs are relatively high, machinery and equipment with a relatively high transmission rate should be used.

 

3. Select from the operator.

4G industrial routers are classified as mobile 4G industrial routers, China Unicom 4G industrial routers, telecom 4G industrial routers, and complete Netcom 4G industrial routers from the standpoint of operators. Most projects can benefit from industrial routers with five-mode and twelve-band (Mobile Unicom 2G/4G/4G, Telecom 4G). The following table corresponds to the style of each frequency band of the operators:

 

4. Select from a variety of belt machine options.

The key to determining the number of machines is to consider the project's specific business scale as well as the overall number of machines and equipment available on the Internet. There are many linked machines and equipment in the natural environment of a huge shopping mall, so a wireless router with a higher number of machines should be used. Most industrial production projects can be considered with 24 wireless network intervention machines and equipment if they are not too demanding.

 

5. Select from interfaces

WLAN ports, LAN ports, 4G sockets, and even serial communication (RS242485422) alternatives are common computer interfaces, depending on whether the sockets are regarded project needs. Some industrial routers, for example, do not support serial communication, thus the project should not consider using internal serial communication to connect to the network; other projects do not require as many WAN ports and can opt for a more cost-effective wireless route with fewer WAN ports.
