It is mainly used in the M2M industry in the Internet of Things industry chain, such as smart grids, smart transportation, Smart home, finance, mobile POS terminal, supply chain automation, industrial automation, smart building, fire protection, public security, environmental protection, meteorology, digital medicine, remote sensing survey, military, space exploration, agriculture, forestry, Water affairs, coal mining, petrochemical and other fields. Four-Faith Industrial 3G Router Commercial 3G Commercial 3G router is a common Internet router for homes or offices, mainly used for office or personal Internet access. . Working principle 3G router mainly embeds wireless 3G module in the original router. First, the user uses a tariff card (SIM card) to plug into the 3G router, and dials up the network through the operator's 3G network WCDMA, CDMA2000, TD-SCDMA, and then can realize data transmission, Internet access, etc. The router has a WIFI function to enjoy the Internet. As long as a mobile phone, computer, or PSP has a wireless network card or has a wifi function, it can access the Internet through a 3G wireless router, which provides an ideal way to realize a wireless local network and enjoy the 3G wireless network. Great convenience. Some manufacturers also have wired broadband interfaces, which can provide normal access to the Internet without 3G. Through 3G wireless routers, broadband connections can be achieved, reaching or exceeding the current ADSL network bandwidth, and becoming very popular in applications such as office and travel or the Internet of Things.

The USB interface of the multifunctional service 3G wireless router can be used as a multifunctional server to help you build a network of your own. When you are out, you can use the office printer and monitor your house through Webcam. Share files with colleagues or friends, and even download FTP or BT files. Mobility and Security With 802.11n wireless access points, the router delivers three times the transmission rate of 802.11b/g network devices and supports data rates up to 300Mbps. So wireless access works everywhere in the room. For example, JCG JGR-N605 also supports the Wi-Fi Protected Setup (WPS) standard, which allows users to establish a secure network with just one button. If you need your network to cover a wider area, the built-in Wireless Distribution System (WDS) cloning function allows you to expand the coverage without adding any cables and lines. Multifunctional Display Tool The unique 3G Management Center is a multifunctional display tool that visually displays signal conditions, allowing users to maximize the use of their connections. You can monitor the video width using upload speed and download speed. This tool can calculate the total amount of data used per month or the total hourly amount. Wireless Settings SSID SSID (Service Set Identifier) ??is the abbreviation of "Service Set Identifier" and is the identifier of the wireless routing network. It is used to identify the identity of wireless devices discovered on a specific wireless network. All workstations and access points must use the same SSID to communicate with each other. SSID is a 32-bit data, and its value is case-sensitive. It can be the physical location identifier of the wireless LAN, your name, the company name, or company name and department, a preferred slogan, or whatever you like. Channel Channel is also called "Channel", which is a data signal transmission channel that uses wireless signals as the transmission medium. Wireless broadband routers can operate on many channels. Various wireless network devices located in the vicinity must be on different channels, otherwise signal interference will occur. If you only have one device, then the default channel value of 6 is probably best. Unless there is a special reason to change the channel (such as interference from Bluetooth, microwave ovens, cell phone towers, or other access points in the area), use the factory defaults. If you have multiple wireless routers and wireless access points on the network, it is recommended to stagger the channels used by each device. For example, the 802.11g and 802.11b wireless standards have 11 channels, but only 3 are non-overlapping channels (channel 1, channel 6, channel 11).

Security Settings Compared with wired networks, data transmitted and received through wireless LANs is more susceptible to eavesdropping. When designing a complete wireless LAN system, encryption and authentication are security factors that need to be considered. The most fundamental purpose of applying encryption technology in wireless LAN is to enable wireless services to achieve the same security level as wired services. To achieve this goal, the IEEE802.11 standard adopts the WEP (Wired Equivalent Privacy: Wired Equivalent Privacy) protocol to set up a specialized security mechanism to encrypt business flows and authenticate nodes. It is mainly used for the confidentiality of link layer information data in wireless local networks. WEP uses a symmetric encryption mechanism, and the same key and encryption algorithm are used for data encryption and decryption. WEP uses an encryption key (also called a WEP key) to encrypt the data portion of each packet exchanged on an 802.11 network. When encryption is enabled, for two 802.11 devices to communicate, they must have encryption enabled and have the same encryption key. WEP encryption is disabled by default, which means no encryption. Parameter optional settings Wireless security parameters are optional settings. There are generally three parameters, as follows: (1) WEP key format: hexadecimal digits; ASCII characters. (2) WEP encryption level: Disable encryption function; 40 (64) bit encryption; 128 bit encryption. The default value is Disable Encryption. (3) WEP key value: set by the user. Wireless routers and wireless network cards that support encryption function work together to encrypt data transmission, making it difficult for others to steal your information midway. There are two WEP encryption levels: 40 (64) bit and 128 bit. Using 128 bit encryption is more secure. The WEP key can be a randomly generated set of hexadecimal numbers, or a user-selected ASCII character. In general, we choose the latter and input it manually. Each wireless broadband router and wireless workstation must use the same key to communicate. But encryption is optional, and most wireless routers disable encryption by default. Encryption may have an impact on transmission efficiency. Optional encryption function To enable the encryption function, please select the WEP key format of "ASCII characters" and select 40 (64) bit or 128 bit WEP key under WEP encryption method (mode). When using the 40 (64)-bit encryption method, you can enter four "different" WEP keys, but you can only choose one to use at the same time. Each key consists of 10 hexadecimal characters. Saved in wireless broadband router. Under Default, select one of the four keys to use. When using the 128-bit encryption method, enter 26 hexadecimal characters as the WEP key. In this case only one key can be entered. Some wireless cards only use 40 (64) bit encryption, so you may want to choose a lower encryption level. If all your clients can support 128-bit encrypted communication, please select 128 bit; if any client can only support 40 (64)-bit encrypted communication, please select 40 (64) bit. To enable encryption, select the encryption type and WEP keys for all wireless routers, access points, and workstations on your network. To increase network security, keys can be changed frequently. When you change the key used by one wireless device, remember to also change the keys for all radios and access points on your network. Basically these are all the security settings of wireless routers. I think everyone should have a comprehensive understanding.
