Method and system for wireless data communication in data processing system

摘要

A method of wireless data communication in a data processing system comprise the steps of providing a wireless data communication device, in which installed are a wireless transceiver module for receiving and transmitting data information, and a controller and an interface module for controlling the wireless data communication device; establishing an information exchange channel between the device and the data processing system based on a serial or parallel connection or wireless communication interface; wherein the wireless data communication device transmits or receives the data information through the wireless transceiver module via a public wireless network. The device is connected with a variety of data processing equipments, such as, a computer host, through a variety of interfaces, and has a wireless transceiver module which can receive or transmit information through a mobile telephone network, uses directly communication services provided by the mobile telephone network company, and thus has the advantages of being online at any time but at low cost. It can also connect to the Internet for transmitting and receiving information so as to realize wireless access to the Internet.
