Tomas Chlebek Kusukela okungenani ezinsukwini ze-antennagate ze-iPhone 4, ukunemba kwenkomba yekhwalithi yesiginali kuma-smartphone kube isihloko esivame ukuxoxwa ngaso. Labo abangayithembi imibuthano engenalutho futhi egcwele ekhoneni lesibonisi bangayishintsha kalula ngenombolo okufanele, okungenani ngokombono, inikeze inani elithembeke kakhulu.
Amandla esignali ngokuvamile akalwa ngama-decibel-milliwatts (dBm). Lokhu kusho ukuthi le yunithi izwakalisa isilinganiso phakathi kwevelu elinganisiwe ne-milliwatt eyodwa (1 mW), ebonisa amandla esignali eyamukelwe. Uma la mandla engaphezulu kuka-1 mW, inani eliku-dBm liphozithivu, uma amandla engaphansi, inani eliku-dBm liyinegethivu.
Endabeni yesignali yenethiwekhi yeselula enama-smartphones, amandla ahlala ephansi, ngakho-ke kukhona uphawu olubi ngaphambi kwenombolo kuyunithi ye-dBm.
Ku-iPhone, indlela elula yokubuka leli nani yilena elandelayo:
- Thayipha *3001#12345#* endaweni yokudayela (Ifoni -> Isidayeli) bese uchofoza inkinobho eluhlaza ukuze uqale ucingo. Lesi sinyathelo sizofaka idivayisi kumodi yokuhlola i-Field (esetshenziswa ngokuzenzakalelayo phakathi nesevisi).
- Uma kuvela isikrini se-Field Test, cindezela bese ubamba inkinobho yokulala kuze kuvele isikrini sokuvala shaqa. Ungaluvali ucingo (uma wenza kanjalo, akukho okubi okuzokwenzeka, kodwa kuzomele uphinde inqubo).
- Cindezela bese ubamba inkinobho yedeskithophu kuze kuvele ideskithophu. Bese, ekhoneni eliphezulu kwesokunxele lesibonisi, esikhundleni semibuthano yakudala, inani lenombolo lamandla esignali ku-dBm lingabonakala. Ngokuchofoza le ndawo, ungakwazi ukushintsha phakathi kwesibonisi sakudala kanye nesibonisi senani lezinombolo.
Uma ufuna ukushintshela ekubonisweni kwakudala kwamandla esignali futhi, phinda isinyathelo 1 futhi ngemva kokuthi isikrini se-Field Test sibonisiwe, mane ucindezele kafushane inkinobho yedeskithophu.
Amanani ku-dBm, njengoba kuchaziwe ngenhla, ahlala engemihle kumadivayisi eselula, futhi lapho inombolo isondela ku-zero (okungukuthi, inenani eliphakeme, kucatshangelwa uphawu olubi), isignali inamandla. Nakuba izinombolo ezivezwa i-smartphone zingenakuthenjelwa ngokuphelele kuzo, zinikeza inkomba enembe kakhulu kunomfanekiso ocacile wesiginali. Lokhu kungenxa yokuthi asikho isiqinisekiso sokuthi isebenza kahle kanjani futhi, ngokwesibonelo, ngisho nezindandatho ezintathu ezigcwele, izingcingo zingase ziphume, futhi ngokuphambene nalokho, ngisho neyodwa ingase isho isignali eqinile ngokwanele ekusebenzeni.
Endabeni yamanani e-dBm, izinombolo ezingaphezulu kuno--50 (-49 nangaphezulu) ziyivelakancane kakhulu futhi kufanele ngokuvamile zibonise ukusondela okudlulele kumthumeli. Izinombolo ukusuka ku -50 kuya ku -70 zisaphakeme kakhulu futhi zanele isignali yekhwalithi ephezulu kakhulu. Amandla esignali avamile futhi avamile ahambisana -80 kuya ku -85 dBm. Uma inani liseduze -90 kuya ku -95, lisho isignali yekhwalithi ephansi, kufika ku -98 engathembekile, kufika ku -100 engathembeki kakhulu.
Amandla esiginali angaphansi kuka -100 dBm (-101 nangaphansi) asho ukuthi awasebenziseki. Kungokwemvelo ukuthi amandla esiginali ahluke ebangeni okungenani lama-dBm amahlanu, futhi izici ezifana nenani lamadivayisi axhunywe kumbhoshongo, inani lamakholi aqhubekayo, ukusetshenziswa kwedatha yeselula, njll., umphumela kulokhu.
kuyilapho lokhu kuthonywa izici ezifana nenani lamadivayisi axhunywe embhoshongweni, inombolo yamakholi aqhubekayo, ukusetshenziswa kwedatha yeselula, njll.
… ukubanjwa kwedivayisi… :-D
uma kungenjalo, uma umuntu esesikrinini sasekhaya, ngokuthepha umunwe kusiginali, ishintsha phakathi kwamachashazi kanye ne-dBm...
Kulungile, umuntu uphoqeleka ukuba amakhodi aqine kanjalo nezinqubo ngezinkinobho, lapho okumele ukwenze nje ukuchofa umunwe wakho kusiginali bese ishintsha iye emuva naphambili. ? Hhayi-ke, okungenani oyedwa uyamangala kumenyu efihliwe, esewusizo. ?
Ngizamile, kodwa ngandlela thize akusebenzanga ngaphandle kwekhodi yedivayisi ye-i7 kanye nesofthiwe yakamuva
Ngine-iP5, i-iOS yakamuva, futhi isebenza ngisho nasesikrinini esikhiyiwe, lapho ufaka ikhodi, nakumadeskithophu anezithonjana. Angazi ukuthi zinjani izinguqulo zakamuva zefoni, ngizobuza ozakwethu. ?
Futhi uma ngifuna ukuyibuyisela esimweni sayo sasekuqaleni? Ngiyabonga
Sibhala embhalweni: Uma ufuna ukushintshela ekubonisweni kwakudala kwamandla esignali futhi, phinda isinyathelo 1 futhi ngemva kokuvezwa kwesikrini se-Field Test, mane ucindezele kafushane inkinobho yedeskithophu.
Kuhle, ngiyabonga kakhulu!
Ingibonisa -110 naseduze -89, ngakho-ke angazi ukuthi iphutha likuphi. Ucingo luyasebenza.
Nginakho lapho - 102 futhi lapho ngishintsha amabhamuza ama-3. Noma kunjalo, isignali ibonakala yanele, yonke into isebenza kahle. Futhi ngokusho kwakho, akufanele ngempela. Hhayi-ke, angazi………………..
