无线数传历史

我国在无线数据通信技术方面,与欧、美、日等发达国家相比,起步较晚,至少落后了20年左右,但发展较快。无线数传电台概念在我国的形成,应该是在改革开放后的80年代初期,但在整个80年代,由于我国的软件及硬件技术还比较落后,系统集成水准还比较低,因此数传电台也只是在水利、电力、自来水等极少数的几个领域进行一些试验性的、小范围的、小批量的应用。看到无线数据通信的发展前景,当时的国家无线电管理委员会还专门辟出了223~235MHz的无线数据通信专用频段,避免了与当时的150MHz、450MHz等语音通信设备争夺有限的频率资源,这一有远见的做法为日后数传电台及遥控遥测系统的快速发展奠定了良好的政策基础。
