Abstract

The invention discloses a wireless facsimile system, which comprises wireless facsimile equipment and a facsimile data server, wherein each piece of wireless facsimile equipment is provided with an interface protection circuit, a user interface circuit, a modem, a dual tone multiple frequency decoding circuit, a central processor and a wireless transmission module, wherein the modem can realize analog-to-digital or digital-to-analog conversion and performs data interaction with the central processor in a first data format; a storage module and a facsimile data conversion module are installed inside the central processor; the central processor is connected with the wireless transmission module and performs data interaction with the wireless transmission module in a second data format; the facsimile data conversion module is used for realizing conversion between the first data format and the second data format; and the facsimile data server is provided with a fixed Internet protocol (IP) address and is connected with the wireless transmission module through the Internet. The wireless facsimile system can be provided with a PSTN (Public Switched Telephone Network) / IP facsimile gateway, so that data interaction with a PSTN is realized and higher universal applicability is further achieved.

Description

technical field [0001] The present invention relates to network communication technology, and more specifically relates to a wireless facsimile system. Background technique [0002] With the development of information and intelligence, the existing fixed office methods can no longer meet the needs of the rapid development of social informatization. More and more business people need mobile business office, which brings new business growth points to wireless communication. Two of the three major components of wireless office: clear voice calls and high-speed wireless data transmission have been fully realized, but the wireless fax service, which is an important part of wireless office, has not been realized. [0003] Currently, the wireless facsimile network available in the 2G mobile communication network is implemented by superimposing the T.30 protocol on the basis of the CSD (Circuit Switch Data) technology in the CS (Circuit Switch) domain. Since CSD technology is a vir...
