Abstract

The invention provides a data card and a radio communication system, the data card includes a radio communication unit for demodulating and decoding received Internet data according to Internet protocol to obtain basic data; a protocol control unit for carrying out 1394 protocol packaging for the basic data according to 1394 protocol to obtain 1394 protocol package data; and a 1394 interface unit for sending the 1394 protocol package data to user terminal. The data card of the embodiment of the present invention employs 1394 interface, solves problem of low output current because present data card uses other interface, and increases transmission rate and access quantity of the data card, based on point-to-point communication characteristic, equipment can directly communicates without participation of third party.

Description

technical field [0001] The invention relates to the technical field of wireless data terminals, in particular to a data card and a wireless communication system. Background technique [0002] At present, wireless data terminals have been widely used and developed, such as PCMCIA interface data cards; Express interface data cards; USB interface data cards; and standard MiniPCI interface data card modules embedded in portable devices such as notebooks, etc. , the basic working principle of the data card with these interfaces is basically to provide the power required for the entire system to work through these interfaces, and then communicate through various data protocols and baseband chips to realize control and data exchange, and then through the baseband, Modules such as RF circuits and antennas, as well as software processing, realize air interface communication with the base station. [0003] figure 1 It is a schematic diagram of the hardware structure of a data card w...
