Working principle of the 4g router with sim solt

4g router with sim slot is a high-speed industrial Internet of Things router, fully compatible with 4G / 3.5G / 3G / 2.5G network, flagship configuration, VPN link, industrial-grade protection, wide temperature design, can easily build high-speed, stable Wireless transmission network, using the public TD-SCDMA network to provide users with wireless long-distance data transmission functions. Generally, a 4G router provides one RS232 (or RS485 / RS422), four Ethernet LANs, one Ethernet WAN, and one WIFI interface. It can be connected to serial devices, Ethernet devices, and WIFI devices at the same time to achieve transparent data transmission and routing. Features.

Mainly embedded wireless 4G module in the original router. First of all, users use a tariff card (SIM card) to plug in a 4G router and dial-up through the operator's 4G network WCDMA and TD-SCDMA to achieve data transmission and Internet access. The router has WIFI function to realize shared Internet access. As long as the mobile phone, computer, psp has a wireless network card or with wifi function, it can access the Internet through a 4G wireless router, which provides great convenience for the wireless LAN to share 3G wireless network. Some manufacturers also have wired broadband interfaces, which can access the Internet normally without 4G. Through 4G wireless routers, broadband connections can be achieved to reach or exceed the current ADSL network bandwidth, which has become very widespread in applications such as the Internet of Things.

Functionally, 4g router with sim slot can be divided into general routers and dedicated routers. Generally speaking, the router is a universal router. Dedicated routers are usually optimized for router interfaces, hardware, etc. to achieve a specific function. For example, the access server is used to access dial-up users to enhance dial-up interfaces and signaling capabilities; broadband access routers emphasize the number and type of broadband interfaces; wireless routers are dedicated to routing connections in wireless networks.
