一、電臺是什么意思

電臺是無線(xian)電(dian)(dian)臺的簡(jian)稱。設有無線(xian)電(dian)(dian)發(fa)(fa)射機(ji)、接(jie)(jie)收(shou)機(ji)和(he)天線(xian)等裝置，用以發(fa)(fa)送(song)或接(jie)(jie)收(shou)無線(xian)電(dian)(dian)信(xin)號的場所(suo)。有時也將(jiang)這些設備稱為電(dian)(dian)臺。從應用角度出發(fa)(fa)可(ke)分為話音傳(chuan)輸的對講(jiang)電(dian)(dian)臺（如(ru)：對講(jiang)機(ji)、車載臺等）和(he)數(shu)據傳(chuan)輸的數(shu)傳(chuan)電(dian)(dian)臺（如(ru)：MDS數(shu)傳(chuan)電(dian)(dian)臺）等。

二、無線電臺的分類有哪些

無線電臺根據(ju)使用頻段或業務范(fan)圍(wei)進行分類。

1、按使用頻段分類，無線電(dian)(dian)臺(tai)根據使用(yong)的頻(pin)段(duan)可(ke)統稱為長(chang)波(bo)電(dian)(dian)臺(tai)、中波(bo)電(dian)(dian)臺(tai)、短波(bo)電(dian)(dian)臺(tai)（也稱高頻(pin)電(dian)(dian)臺(tai)）、超短波(bo)電(dian)(dian)臺(tai)、微(wei)波(bo)電(dian)(dian)臺(tai)等。

2、按業務范圍分類，設置在地球表面(mian)(mian)或地球大(da)氣層主要(yao)部分(fen)(fen)以內(nei)的物體上的電(dian)臺，統稱為地面(mian)(mian)電(dian)臺。地面(mian)(mian)電(dian)臺可分(fen)(fen)為：
