Eminyakeni yamuva, ngenjongo yokonga izindleko nokunciphisa ukuphindaphinda kokwakhiwa, izinhlelo eziningi zokusabalalisa zasendlini zamukele imodeli yesistimu ehlanganisiwe eminingi eyabelana ngekamelo nezinye izinhlelo ezincane. Lokhu kusho ukuthi amasiginali wezinhlelo eziningi kanye nama-multi-band ahlanganiswa ngaphakathi kwezinkundla ezihlangene ezivamile futhi kwabelwane ngezinhlelo zokusabalalisa zasendlini ukuze kuzuzwe ukudluliswa kwamabhendi amaningi, amasistimu amaningi, indlela eyodwa, noma izindlela ezimbili.
Inzuzo wukunciphisa ukuphindaphindeka kwengqalasizinda nokonga indawo. Kodwa-ke, izinkinga ezibangelwa izinhlelo ezinjalo zokusabalalisa ngaphakathi endlini ziya zigqama kakhulu. Ukuhlalisana kwamasistimu amaningi ngokungagwemeki kwethula ukuphazamiseka phakathi kwesistimu. Ikakhulukazi, amabhendi efrikhwensi yokusebenza ayafana, futhi amabhendi esikhawu mancane, ukukhishwa okuyinkohliso kanye ne-PIM phakathi kwamasistimu ahlukene nakho kuyathinteka.
Kulokhu, idivayisi yokwenziwa yekhwalithi enhle inganciphisa imiphumela yalokhu kuphazamiseka. Idivayisi ye-RF yezinga eliphansi ye-passive nayo izoholela ekwehleni kwezinye izinkomba zenethiwekhi, futhi amadivayisi wekhwalithi ephezulu azoba nomthelela omuhle kukhwalithi yenethiwekhi, ukuvimbela ukwenzeka kwezinto ezikhishwayo ezingamanga, ukuphazamiseka, nokuzihlukanisa.
Izinhlobo eziyinhloko zokugxambukela kumanethiwekhi angenawaya zihlukaniswe ngokuphazamiseka kwesistimu nokuphazanyiswa phakathi kwesistimu. Ukugxambukela kwesistimu kubhekisela ekudukeni kwebhendi yokudlulisa, ewela ekuphazamisekeni kwesistimu ngokwayo okubangelwa ibhendi eyamukelayo. Ukuphazamiseka kwe-Inter-system ikakhulukazi ukukhishwa okungamanga, ukuhlukaniswa komamukeli, kanye nokuphazamiseka kwe-PIM.
Ngokuya ngenethiwekhi evamile nesimo sokuhlola, amadivaysi angenzi lutho ayingxenye ebalulekile ethinta amanethiwekhi avamile.
Izici eziyinhloko zokwenza ingxenye enhle ye-passive zifaka:
1. Ukuzihlukanisa
Ukuhlukaniswa okungalungile kuzodala ukuphazamiseka phakathi kwamasistimu, ukuqhutshwa kwe-PIM elahlekile kanye ne-multi-carrier carrier, bese kuthikamezeka nesignali ekhuphukayo yomfula.
2. VSWR
Esimeni se-VSWR yezingxenye ze-passive inkulu uma kuqhathaniswa, isiginali ebonisiwe iba nkulu, ezimeni ezimbi kakhulu isiteshi esiyisisekelo sizokwaziswa ngokulimala kwezakhi ze-RF nezikhulisamandla.
3. Ukwenqatshwa ku-out-of-band
Ukwenqatshwa okungekuhle ngaphandle kwebhendi kuzokhuphula ukuphazamiseka kwesistimu, kodwa ikhono elihle lokuvimbela ngaphandle kwebhendi, kanye nokuhlukaniswa kwembobo okuhle kuzosiza ukunciphisa ukuphazamiseka phakathi kwamasistimu.
4. I-PIM - I-Intermodulation engenzi lutho
Imikhiqizo emikhulu ye-PIM iwela kubhendi ekhuphuka nomfula izobangela ukonakala kokusebenza komamukeli.
5. Umthamo wamandla
Endabeni yenkampani yenethiwekhi eminingi, ukuphuma kwamandla aphezulu, kanye nesignali yesilinganiso esiphakeme kakhulu, umthamo wamandla onganele uzoholela ekulayisheni okuphezulu kwesistimu. Lokhu kubangela ukuthi ikhwalithi yenethiwekhi yehle kakhulu, okubuye kubangele izimo ze-arcing nezomlilo. Ezimweni ezimbi kakhulu, kungenzeka ukuphula noma ukushisa imishini, okubangela ukuba inethiwekhi yesiteshi sesisekelo iwa.
6. Inqubo yokucubungula idivayisi nezinto zokwakha
Izinqubo zokubalulekile nokucubungula azivaliwe, okuholela ngokuqondile ekonakaleni kokusebenza kwepharamitha yedivayisi, kuyilapho ukuqina kwedivayisi nokuvumelana nezimo zemvelo kwehliswa kakhulu.
Ngaphezu kwezici eziyinhloko ezingenhla, kunezici ezithile ezijwayelekile njengalezi ezilandelayo:
1. Ukulahlekelwa kokufaka
Ukulahlekelwa kokufakwa ngokweqile kwenza isignali ilahlekelwe amandla engeziwe kusixhumanisi esithinta ukumbozwa, kuyilapho ukukhulisa isiteshi esiqondile kuzokwethula ukuphazamiseka okusha, futhi ukumane kuthuthukise amandla okudlulisela esiteshini esiyisisekelo akunabungani bemvelo, futhi nangale komugqa we-amplifier uhla lokusebenza olulungile lomugqa. lapho ikhwalithi yesiginali yesidlulisi izowohloka, izothinta ukugcwaliseka okulindelekile komklamo wokusabalalisa wasendlini.
2. Ukushintshashintsha kwe-in-band
Ukushintshashintsha okukhulu kuzoholela ekucabaneni okubi kwesignali engaphakathi kwebhendi, lapho kukhona abathwali abaningi abazovala umthelela, futhi kuthinte ukuqaliswa okulindelekile kwedizayini yokusabalalisa endlini.
Ngakho-ke, izingxenye ze-passive zidlala indima ebalulekile ekwakhiweni kwesiteshi sesisekelo senethiwekhi ye-ae.
I-Jingxin igxile kuukwenza ngokwezifiso izingxenye ze-passiveokudingekayo kumakhasimende, kungaba kusukela ekuhloleni kokuqala, iseluleko sedizayini yamaphakathi nethemu, noma ukukhiqizwa kwenqwaba yakamuva, sithobela ikhwalithi kuqala, ukuze sinikeze amasevisi kumakhasimende emhlabeni jikelele.
