YiniI-Two Way Radio?
Ngo-1936, inkampani ye-Motorola walkie talkie yase-United States yakha umkhiqizo wokuqala wokuxhumana ngomsakazo weselula - "i-patrol brand" ye-amplitude module module imoto esamukeli.Ngokuthuthuka cishe kwekhulu le-3 / 4, ukusetshenziswa kwe-walkie talkie kuye kwanda kakhulu, futhi kusuke endaweni ekhethekile kuya ekusetshenzisweni okuvamile, kusukela ku-walkie talkie yezempi kuya ku-civil.u-walkie talkie.Ikonahhayi kuphela ithuluzi lokuxhumana elingenazintambo elichwepheshile ekuxhumaneni kweselula, kodwa futhi ithuluzi labathengi elinezici zemikhiqizo yabathengi engahlangabezana nezidingo zokuphila kwabantu.Njengoba igama lisho, mobileukuxhumana ukuxhumana phakathi kweqembu elilodwa kanye nelinye iqembu kumakhalekhukhwini.Kubandakanya abasebenzisi beselula kubasebenzisi beselula, abasebenzisi beselula kubasebenzisi abangaguquki, futhi vele, abasebenzisi abangaguquki kubasebenzisi abangaguquki.I-intercom yomsakazo iyi-igatsha ezibalulekile zokuxhumana mobile.
Isiteshi somsakazo sase-US 611
Umsakazo we-Two way, noma i-transceiver, noma i-walkie talkie uhlobo lwemishini yomsakazo engasakaza futhi yamukele ukusakazwa komsindo.Eqinisweni, wonke umuntu usebenzise uhlobo oluthile lwerediyo yezindlela ezimbili ekuphileni kwabo.Izinhlobo zamadivayisi ahlukaniswa njengemisakazo yezindlela ezimbili kusukela ku-'walkie talkies' elula kuye kumamonitha ezingane kuya kumaselula asetshenziswa empilweni yansuku zonke.
Isebenza kanjani i-Two Way Radio?
I-Walkie talkiesithathwa njengemisakazo enezindlela ezimbili.Ngokuvamile kunezinhlobo ezimbili ezahlukene zemisakazo yezindlela ezimbili, i-simplex ne-duplex.Imisakazo ye-Simplex two way ihlukaniswa njengemisakazo esebenzisa isiteshi esisodwa ukudlulisa ulwazi.Lokhu kusho ukuthi noma nini, oyedwa kuphela engxoxweni ongakhuluma futhi azwakale.Umsakazo we-two-way ovame kakhulu umsakazo ophathwa ngesandla noma i-walkie talkie, evamise ukuba nenkinobho 'yokucindezela ukuze ukhulume' ukuze iqalise ukudlulisa usuka kwenye iyunithi iye kwenye.Ngesikhathi esifanayo, umsakazo we-duplex wezindlela ezimbili usebenzisa amaza omsakazo amabili ahlukene ngesikhathi esisodwa, okwenza ikhono lokuqhuba izingxoxo eziqhubekayo.Isibonelo esivamile salolu hlobo lwerediyo yezindlela ezimbili umkhiqizo osetshenziswa abantu abaningi ezimpilweni zabo zansuku zonke, njengamafoni angenazintambo noma omakhalekhukhwini.
Uma imisakazo emibili iphakathi kwebanga elithile, ingaxhumana ngesikhathi esisodwa, kodwa futhi ingaxhumana ngesiteshi esisodwa uma ingaphandle kwebanga.Imisakazo yezindlela ezimbili enaleli khono ivame ukubizwa ngokuthi yimishini ye-intercom, izinsiza eziqondile, noma imoto eya emishinini yemoto.Eminye imisakazo yezindlela ezimbili isebenzisa ubuchwepheshe be-analog, kanti eminye isebenzisa ukusakaza.Ngokwedijithali, kokubili kunezinzuzo kanye nokubi, njengakudala.Uma isignali ibuthakathaka noma inomsindo, ukusetshenziswa kwezimpawu ze-analog kunamakhono angcono okuxhumana, kodwa njengoba kushiwo ngenhla, uhlangothi olulodwa kuphela lwengxoxo lungabanjwa ngesikhathi.
Imisakazo ephathekayo ye-shortwave isetshenziswe amasosha nezinhloli amashumi eminyaka ngoba ivumela ukuxhumana okukude okubili ngaphandle kwesidingo sengqalasizinda yomsakazo wendawo.
