無線電對講機是(shi)最早被(bei)人類使用(yong)(yong)的無線(xian)(xian)移(yi)動通(tong)(tong)(tong)(tong)(tong)信(xin)(xin)(xin)設備(bei)，早在二十世紀(ji)三十年代就開始得(de)到應(ying)用(yong)(yong)。已從專業(ye)化領域走向普通(tong)(tong)(tong)(tong)(tong)消(xiao)費(fei)，從軍用(yong)(yong)擴展(zhan)到民用(yong)(yong)。它既是(shi)移(yi)動通(tong)(tong)(tong)(tong)(tong)信(xin)(xin)(xin)中的一(yi)種(zhong)專業(ye)無線(xian)(xian)通(tong)(tong)(tong)(tong)(tong)信(xin)(xin)(xin)工具，又是(shi)一(yi)種(zhong)能滿(man)足人們(men)生活需要(yao)的具有(you)消(xiao)費(fei)類產品特點的消(xiao)費(fei)工具。顧名思義移(yi)動通(tong)(tong)(tong)(tong)(tong)信(xin)(xin)(xin)就是(shi)通(tong)(tong)(tong)(tong)(tong)信(xin)(xin)(xin)一(yi)方和(he)另一(yi)方在移(yi)動中實現通(tong)(tong)(tong)(tong)(tong)信(xin)(xin)(xin)。它包括(kuo)移(yi)動用(yong)(yong)戶對(dui)移(yi)動用(yong)(yong)戶、移(yi)動用(yong)(yong)戶對(dui)固(gu)(gu)定(ding)用(yong)(yong)戶、當然(ran)又包括(kuo)固(gu)(gu)定(ding)用(yong)(yong)戶對(dui)固(gu)(gu)定(ding)用(yong)(yong)戶之間進行通(tong)(tong)(tong)(tong)(tong)信(xin)(xin)(xin)聯系，無線(xian)(xian)電對(dui)講機就是(shi)移(yi)動通(tong)(tong)(tong)(tong)(tong)信(xin)(xin)(xin)中的一(yi)個重要(yao)分支。

這種(zhong)通(tong)(tong)信方式(shi)和其它通(tong)(tong)信方式(shi)有(you)不同(tong)的特點：即時(shi)(shi)溝通(tong)(tong)、一(yi)呼(hu)百應、經(jing)濟實用(yong)(yong)、運(yun)營成(cheng)本(ben)低、不耗費(fei)通(tong)(tong)話費(fei)用(yong)(yong)、節約(yue)使用(yong)(yong)方便(bian)，同(tong)時(shi)(shi)還具有(you)組呼(hu)通(tong)(tong)播、系統呼(hu)叫、機密呼(hu)叫等(deng)功能(neng)。在處理緊急(ji)突(tu)發(fa)事(shi)件中(zhong)，在進行(xing)調(diao)度指揮中(zhong)其作用(yong)(yong)是其它通(tong)(tong)信工具所不能(neng)替代的。

無(wu)線(xian)電(dian)(dian)對(dui)講機和其它無(wu)線(xian)通信工具(ju)（如(ru)手機）其市場定(ding)位各不相同，難以(yi)互相取(qu)代。無(wu)線(xian)電(dian)(dian)對(dui)講機決不是過時(shi)的(de)產品。它還(huan)將長期使用(yong)下去。隨(sui)著經濟的(de)發展，社會的(de)進步，人們更(geng)關(guan)注自身的(de)安全、工作(zuo)效率和生(sheng)活質量的(de)提高，對(dui)無(wu)線(xian)電(dian)(dian)對(dui)講機的(de)需求(qiu)也(ye)將日(ri)益(yi)增長。公眾對(dui)講機的(de)大量使用(yong)，更(geng)促進了無(wu)線(xian)電(dian)(dian)對(dui)講機和有線(xian)電(dian)(dian)話機一樣成為人們喜(xi)愛和依賴的(de)通信工具(ju)。
