Ukusetyenziswa kwe-Two Way Radio

Yintoni iIrediyo yeNdlela ezimbini?

Ngo-1936, inkampani ye-Motorola walkie talkie yase-United States yavelisa imveliso yokuqala yonxibelelwano lukanomathotholo- "i-patrol brand" ye-amplitude modulation yemoto esamkeli sikanomathotholo.Ngophuhliso malunga ne-3/4 yenkulungwane, ukusetyenziswa kwe-walkie talkie kuye kwaxhaphaka kakhulu, kwaye iye yasuka kwintsimi ekhethekileyo ukuya kusetyenziso oluqhelekileyo, ukusuka kwi-walkie talkie yasemkhosini ukuya kwi-civil.hamba ithetha.Yikungekuphela nje isixhobo sonxibelelwano esingenazintambo kunxibelelwano oluphathwayo, kodwa isixhobo somthengi esineempawu zeemveliso zabathengi ezinokuhlangabezana neemfuno zobomi babantu.Njengoko igama lisitsho, mobileunxibelelwano lunxibelelwano phakathi kweqela elinye kunye nelinye iqela kwiselula.Ibandakanya abasebenzisi beselula kubasebenzisi beselula, abasebenzisi beselula kubasebenzisi abasisigxina, kwaye kunjalo, abasebenzisi abalungisiweyo kubasebenzisi abasisigxina.I-intercom yerediyo yi-isebe ebalulekileyo yonxibelelwano mobile.

Isikhululo sikanomathotholo sase-US 611

Irediyo yeendlela ezimbini, okanye i-transceiver, okanye i-walkie talkie luhlobo lwesixhobo sikanomathotholo esinokusasaza kwaye sifumane usasazo oluvakalayo.Ngapha koko, wonke umntu usebenzise uhlobo oluthile lwerediyo yeendlela ezimbini ebomini babo.Iindidi zezixhobo ezichazwe njengoonomathotholo beendlela ezimbini ukusuka kwii-'walkie talkies' ezilula ukuya kwiimonitha zomntwana ukuya kwiiselfowuni ezisetyenziswa kubomi bemihla ngemihla.

Isebenza njani iTwo Way Radio?

Walkie talkieszithathwa ngokuba simplex iindlela ezimbini radios.Ngokuqhelekileyo kukho iindidi ezimbini ezahlukeneyo zerediyo ezinezindlela ezimbini, i-simplex kunye ne-duplex.Oonomathotholo be-Simplex beendlela ezimbini bahlelwa njengonomathotholo abasebenzisa ijelo elinye ukusasaza ulwazi.Oku kuthetha ukuba nangaliphi na ixesha, mnye kuphela umntu okwincoko onokuthetha aze aviwe.Eyona nto ixhaphakileyo yerediyo yeendlela ezimbini yirediyo ephathwayo okanye i-walkie talkie, edla ngokuba neqhosha 'lokucofa ukuze uthethe' ukuqalisa usasazo ukusuka kwenye iyunithi ukuya kwenye.Kwangaxeshanye, unomathotholo ophindwe kabini usebenzisa amaza erediyo amabini ahlukeneyo ngaxeshanye, edala ukukwazi ukuqhuba iincoko eziqhubekayo.Umzekelo oqhelekileyo wolu hlobo lwerediyo yeendlela ezimbini yimveliso esetyenziswa ngabantu abaninzi kubomi babo bemihla ngemihla, njengeefowuni ezingenazintambo okanye iiselfowuni.

Xa oonomathotholo ababini bephakathi koluhlu oluthile omnye komnye, banokunxibelelana ngaxeshanye, kodwa banokunxibelelana ngesitishi esinye xa bengekho kuluhlu.Iindlela ezimbini zoonomathotholo abanalo buchule badla ngokubizwa ngokuba zizixhobo ze-intercom, izixhobo ezithe ngqo, okanye imoto kwizixhobo zemoto.Ezinye iirediyo ezineendlela ezimbini zisebenzisa itekhnoloji ye-analog, ngelixa ezinye zisebenzisa usasazo.Ngokwedijithali, zombini zineengenelo kunye nezingeloncedo, njengakwixesha elidlulileyo.Xa umqondiso ubuthathaka okanye unomsindo, ukusetyenziswa kweempawu ze-analog kunamandla onxibelelwano olungcono, kodwa njengoko kukhankanyiwe ngasentla, kuphela icala elinye lengxoxo linokubanjwa ngexesha.

Iirediyo eziphathwayo ze-shortwave zisetyenziswe ngumkhosi kunye neentlola amashumi eminyaka kuba zivumela unxibelelwano lweendlela ezimbini ezikude ngaphandle kwesidingo seziseko zoncedo zikanomathotholo zasekhaya.
