Ayikwazi ukwamukela isignali yocingo lukamakhalekhukhwini endaweni engaphansi.Kungakhathaliseki ukuthi uhlangabezana nezimo eziphuthumayo ezindaweni zokupaka ezingaphansi komhlaba ezidinga ukuxhumana, noma ukungakwazi ukuxhumana nabangane ezindaweni zezitolo ezingaphansi komhlaba, lezi yizindawo ezibuhlungu ekuphileni kwethu kwansuku zonke.Manje, sikunikeza aukusabalala kwesignaliisixazululo esikuvumela ukuthi ukhulume ngaphandle kokuphazamiseka ngisho nangaphansi.
Isembozo esingaphansi esisembozo socingo lukamakhalekhukhwini lokuqinisa isignali iyithuluzi elikhethekile.Njengoba ungasakhawulelwa yisikhala, uzokwazi ukujabulela isignali yocingo oluqinile oluzinzile futhi olusezingeni eliphezulu noma yikuphi endaweni engaphansi.Noma ngabe ukuxhumana, ukuthumela umbhalo, noma ukusefa i-inthanethi, kulula futhi kulula ukuhlala uxhumene nomndeni nabangane.Ngakho-ke, ama-amplifiers amasignali omakhalekhukhwini aya ngokuya evame kakhulu empilweni yesimanje.
Ezindaweni ezinezixuku eziminyene noma ukumbozwa kwesignali okubuthakathaka, izimpawu zocingo zingase ziphazamiseke noma zingakwazi ukuxhunywa.Isikhulisi sesiginali yeselula singasetshenziswa futhi ukuthuthukisa ngempumelelo ukuzinza nekhono lokwamukela isignali futhi kuqinisekiswe ikhwalithi yokushaya kanye nokushelela kokudluliswa kwedatha.
IIsiqinisi isiginali yeselula engaphansiiyidivayisi engakwazithuthukisa isignali yeselulafuthi wandise ukusabalala kwesignali.Kwezinye izindawo, isignali yeselula ivamise ukuvinjwa, okuholela esignali ebuthaka noma ukungabikho nhlobo uxhumano.Ukufaka isikhulisi sesignali kungaxazulula le nkinga ngokuvala wonke amakhona esignali, siqinisekise ukuthi singasebenzisa ifoni yethu ngokukhululeka noma yikuphi.Umgomo oyinhloko uwukwamukela amasignali ezintini zangaphandle bese uziguqula zibe amasignali aqinisiwe ngokusebenzisa izimpondo ezingaphakathi ukuze zisetshenziswe omakhalekhukhwini.Isimiso sokusebenza semishini yokukhulisa isignali yesignali yocingo lweselula ihluke kancane, kodwa iphuzu elivamile ukunqanda isignali yokuxhumana ngocingo eyayithunyelelwe umakhalekhukhwini ekuqaleni, bese udlulisela kabusha isignali kumakhalekhukhwini ngamandla aphakeme.
Umgomo wokusebenza weisisekelo sokuqinisa isignali yeselulailula uma kuqhathaniswa.Iqukethe izingxenye ezintathu eziyinhloko: i-antenna yangaphandle, i-antenna yasendlini, ne-amplifier yesignali.Okokuqala, uthi olungaphandle lwamukela futhi ludlulisele isignali yocingo lwangaphandle ku-amplifier yesignali.Isikhulisi sesignali sikhulisa amandla esiginali eyamukelwe futhi siyidlulisele ku-antenna yasendlini.Ekugcineni, i-antenna yasendlini izovala yonke indawo yasendlini ngesignali yeselula ekhulisiwe, ibone ukumbozwa okugcwele kweisignali engaphansi.
Isitezi esingaphansi sokuqinisa isignali yocingo lweselula siyisixazululo esikahle.Ingakwazi ukumboza ngokugcwele isignali Yefoni Ephathwayo egumbini elingaphansi, ixazulule inkinga yesignali ebuthakathaka noma engekho, inikeze uxhumano lwesignali ezinzile, futhi inciphise imisebe yomakhalekhukhwini.I-speakeasy, amagumbi angaphansi kanye nezindawo zokupaka ezingaphansi komhlaba ezinezimpawu ezibuthakathaka zingase zicabange ukusebenzisaIzithuthukisi zesignali yeselulaukuletha umuzwa ongcono wokuxhumana ngomakhalekhukhwini endaweni yakho engaphansi.
