數(shù)傳電臺是無線數(shù)據(jù)傳輸電臺的簡稱，而數(shù)據(jù)傳輸最早出現(xiàn)的應(yīng)用是數(shù)據(jù)遙控遙測，有別于目前無線微波電臺、無線以太網(wǎng)、GPRS手機(jī)等先進(jìn)數(shù)據(jù)傳輸設(shè)備，習(xí)慣上，數(shù)傳電臺就指傳遙控遙測數(shù)據(jù)用的電臺，我國無線電管理部門把223~235M/821~
825M/2.4~2.4835GHz等頻段指配給數(shù)傳業(yè)務(wù)（參2）。數(shù)據(jù)遙控遙測是隨著采用計(jì)算機(jī)進(jìn)行數(shù)據(jù)處理而應(yīng)生的業(yè)務(wù)，而六、七十年代只有模擬FM調(diào)制技術(shù)的音頻（300~3400Hz）通信電臺，因此把101010……數(shù)據(jù)流通過單頻（如FSK的1=1200 Hz，0=1800 Hz）來代表，再作為音頻信號進(jìn)行模擬FM調(diào)制就實(shí)現(xiàn)了早期的數(shù)傳電臺，其本質(zhì)是預(yù)FSK（或MSK、GMSK）調(diào)制加FM調(diào)頻這樣的二次調(diào)制（參3），如下圖所示：
模擬數(shù)傳電臺示意圖
以嘉興藍(lán)波數(shù)傳電臺N88X為例，其實(shí)質(zhì)就是采用單片機(jī)（232數(shù)據(jù)打包解包、電臺收發(fā)控制等）及專用FSK（或MSK、GMSK）芯片預(yù)調(diào)制而做成無線MODEM，再配上日本日精模擬FM調(diào)頻對講機(jī)（藍(lán)波公司提供的日精電臺N889信產(chǎn)部電臺入網(wǎng)證書中注明調(diào)制方式為FM，http://www.rec198.com）。
由于調(diào)頻對講機(jī)和MODEM已大量普及民用，價(jià)格低（如日精ND889 25W電臺，成本約為500元人民幣，藍(lán)波4800MODEM成本約為200元人民幣）是它的最大優(yōu)勢，但缺陷亦是明顯的，廣大用戶及專業(yè)人員都知道，
