Abstract

A dual mode wireless network card serves for supporting a GPRS communication device and a wireless receiver. The wireless network card is connected to a GPRS communication device and a wireless receiver. The GPRS communication device uses a PPP communication protocol for using in far-end data communication; the wireless receiver transmits data through a gateway for performing near-end data communication. The wireless network card includes a driving program for switching. When the GPRS communication device is turned off, the wireless network card is switched to the wireless receiver for near-end transmission. The wireless network card can be switched to the GPRS communication device so as to be used suburbs. When the user is indoors with the GPRS communication device being turned on. The wireless network card scans the wireless receiver; if there are signals of the wireless receiver, then the mode is switched for receiving signals of wireless receiver.
