Dual communication mode wireless network transmission device

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.

FIELD OF THE INVENTION

The present invention relates to wireless communication, and particular to a wireless network transmission device which uses the network communication protocol module and mobile phone communication protocol module in parallel so that data can be transmitted effectively with a higher quality by the alternative use of the two protocol.

BACKGROUND OF THE INVENTION

With the improvement of wireless communication, the notebook computers (or even other computer devices, or PDAs (personal digital assistants, etc) can communicate wirelessly by wireless networks or through mobile phones. In general, one notebook computer is equipped only one kind of protocol so that the users only select one communication way to communicate wirelessly. However, since the wireless device is strictly confined by the coverage defined by base stations. Thereby, it is often that the communication quality is not good.

However, if the user can switch between devices using the two communication protocols so that it can select one with preferred signal quality, then a preferred communication will be acquired.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a wireless network transmission device which uses two protocols for communication so as to have a preferred communication quality.

To achieve above object, the present invention provide a wireless network transmission device. 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, two data of different protocol being transmitted in parallel. 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.

DETAILED DESCRIPTION OF THE INVENTION

With reference toFIG. 1, the present invention provides a system for parallel using a wireless network card and a mobile phone. The system comprises the following elements.

A wireless network transmission device1includes a network control chip2, a communication control chip3and a control chip set4which are arranged in parallel. The network control chip2, communication control chip3, and control chip set4are connected to a module5and a module6through a bus. The module5is connected to an external network communication protocol module7and the module6is connected an external mobile phone communication protocol module8. Thereby, the system can communicate with the network communication protocol module7and mobile phone communication protocol module8in parallel over different sections. Thereby, two data of different protocol can be transmitted in parallel.

The control chip set4serves to connect a PCMCIA interface9to the module5and module6through network control chip2and the communication control chip3.

In the present invention, the protocol of the network communication protocol module7can selected from one of for example WLAN802.11a/b/b+/g/g+ and the protocol of the mobile phone communication protocol module8is selected from one of for example GPRS, CDMA, WCDMA, CDMA1X, TD-CDMA.

With reference toFIG. 2, one embodiment of the present invention is illustrated. The wireless network transmission device1is installed to a notebook computer10. Initially, the notebook computer10is communicated with a mobile phone11through the network communication protocol module7. When the wireless network transmission device1is near the coverage of a base station, but not in the coverage. The data to be transmitted in the network transmission and receiving end12is by using the mobile phone communication protocol module8.

Advantages of the present invention are that two protocols are used at the same time so that the communication will not confined in a narrow coverage. Thereby, when the quality of signal is not good, the module can be changed so that the decay of signals can be avoided.
