The working principle of 3g internet router

2018.07.21
The working principle of 3g internet router 3g internet router is mainly embedded the wireless 3G module in the original router. Firstly, users plug a SIM card to the 3g internet router. The functions of data transmission and surfing the Internet can be achieved by the dial-up networking of 3g network WCDMA, CDMA2000, TD-SCDMA of the operator. The router can realize the sharing of the Internet by the function of WIFI. It can access the Internet through the 3g internet router as long as the mobile phone, computer, PSP has a wireless card or WIFI function, which provides great convenience to achieve the sharing 3g wireless network of wireless local area networks. The routers of some manufacturers also have a cable broadband access, which allows it to access to the Internet without 3g. Broadband connections can be achieved through 3g internet router, which can meet or exceed the network bandwidth of current ADSL. It has been widely used in office, travel or Internet of things. The reason why 3g internet router can connect heterogeneous networks is that the routers need to strip off the frame header and the end of the frame of the data they received to get the data packet inside. If the router tends to forward a data packet, it will need to reseal this packet with the frame that is newly connected and used with the data link layer protocol conformance. For example, routers first receive an ethernet frame from a port of local area network. It extracts the data packets and then construct a frame of the frame relay that is used in wide area network. After that, it sends a new frame from a port that is connected to a wide area network. The data packets in the frames remain unchanged in the process of router splitting and rebuilding the frames.
