无线传真作为 GSM的一项新的数据业务 ,广泛适用于新闻采访、交通运输、移动办公、公安缉毒等领域 ,改变了过去传真机只能固定收发传真的状况。本文阐述了以微机为平台、以无线 Modem卡为核心的仿真传真通信系统 ,以仿真无线发送传真为例 ,讨论了 GSM网络传真通信规程 As a new data service of GSM, wireless fax is widely used in the areas of news gathering, transportation, mobile office, public security and anti-drug and so on. It changed the situation that fax machines could only send and receive faxes in the past. This paper describes the simulation of fax communication system based on microcomputer as the platform and wireless modem as the core, taking the simulation of wireless transmission of fax as an example, discusses the GSM network fax communication protocol
