A wireless network transmission device is disclosed. A network control chip, a communication control chip and a control chip set are arranged in parallel. The network control chip, communication control chip, and control chip set are connected to the first module and the second module through a bus. The first module is connected to an external network communication protocol module and the second module is connected an external mobile phone communication protocol module. Thus, the system is communicable with network communication protocol module and mobile phone communication protocol module in parallel; thereby, data of different protocols being transmitted in one device. The control chip set serves to connect a PCMCIA interface to the first module and second module through the network control chip and the communication control chip.
