Abstract

The invention provides a data card and a transmission method based on the data card, and solves the problems in the prior art that the data card of an universal serial bus (USB) interface can not support network data transmission in long distance. The data card comprises an Ethernet port used for being connected with external equipment, an internet port controller and a processor. The internet port controller is connected with the Ethernet port and used for controlling communication between the Ethernet port and the external equipment. The internet port controller is further connected with the processor in a communication mode. Through adoption of the Ethernet port, the data card can support network data transmission in long distance.

Description

technical field [0001] The invention relates to the communication field, in particular to a data card and a transmission method based on the data card. Background technique [0002] At present, most data cards transmit data through the Universal Serial Bus (USB, Universal Serial BUS) interface. For example, connect the data card to a personal computer (PC, personal computer) through the USB interface, and realize the operation of the data card through the driver program on the PC side. and control, such as surfing the Internet and transferring data. [0003] However, due to the limitation of the USB protocol, the data cable of the USB interface generally cannot be too long. When the computer is fixed, the transmission range of the USB data cable is relatively limited, so that the data card using the USB interface cannot be moved in a large range. For example, when the communication signal in the area where the computer is located is not very good, use a longer USB data cabl...
