Abafundi abaningi bebelokhu bebuza ukuthi iyiphi inzuzo namandla amapharamitha we-aophinda isignali yeselulazisho mayelana nokusebenza. Bahlobene kanjani? Yini okufanele uyicabangele lapho ukhetha isiphindaphindi sesiginali yeselula? Lesi sihloko sizocacisa inzuzo namandla eziphindaphinda zesiginali yeselula.Njengomkhiqizi ochwepheshe wesiginali yeselula ephindayoiminyaka engu-12, sizokutshela iqiniso.
I-Lintratek KW27B Isiphindaphindi Sesiginali Yeselula
Ukuqonda Inzuzo namandla Eziphindaphinda Zesiginali Yeselula
Inzuzo namandla amapharamitha amabili abalulekile weziphindaphinda zesiginali yeselula:
Zuza
Inzuzo ivamise ukukalwa ngama-decibel (dB) futhi imele izinga lowo ophindayo akhulisa ngalo isignali. Empeleni, i-booster yesiginali yeselula, eyaziwa nangokuthi isiphindisi sesignali yeselula, idlulisela amasignali ukusuka ezindaweni ezinokwamukela okuhle kuya kulezo ezinezimpawu ezibuthakathaka.Inzuzo ibhekana nenkinga yokuncishiswa kwesignali yeselula okwenzeka ngesikhathi sokudlulisela ngamakhebuli.
Lapho uthi luthola amasignali eselula, amasignali angase alahlekelwe ngamazinga ahlukahlukene ngesikhathi sokudluliselwa ngamakhebuli noma izihlukanisi.Uma isignali idinga ukudluliselwa, iba phezulu inzuzo edingekayo kusukela kusiphindayo sesignali yeselula. Ngaphansi kwesimo esifanayo, ukuzuza okuphezulu kusho ukuthi ophindayo angakwazi ukudlulisela amasignali kumabanga amade.
Ngakho-ke, isitatimende esilandelayo esivame ukutholakala ku-inthanethi siakulungile: Inzuzo ikhombisa ngokuyinhloko ikhono lophindayo lokuthuthukisa amasignali. Ukuzuza okuphezulu kubonisa ukuthi ngisho namasignali amaselula abuthakathaka angakhuliswa kakhulu, ngaleyo ndlela kuthuthukiswe ikhwalithi yesignali.
Ngokudlulisa isignali yebanga elide, sincoma ukusebenzisa i-fiber optics njengendawo yokudlulisela, njengei-fiber optic repeatersithola ukuncishiswa kwesignali okuncane kakhulu kunezintambo zendabuko ze-coaxial.
Amandla
Amandla asho amandla esignali yokuphumayo evela kusiphindayo, ngokuvamile esikalwa ngama-watts (dBm/mW/W). Inquma indawo yokumboza yesiginali kanye nekhono layo lokungena izithiyo. Ngaphansi kwesimo esifanayo, isilinganiso samandla esiphezulu siphumela endaweni ebanzi.
Okulandelayo yithebula lokuguqulwa lamayunithi amandla i-dBm ne-mW
kw40B Isiphindaphindi Sesiginali Yeselula
Kuhlobene Kanjani Inzuzo namandla?
Lawa mapharamitha amabili awaxhumene ngokwemvelo, kodwa ngokuvamile, isiphindaphinda sesiginali yeselula esinamandla aphezulu sizophinde sibe nenzuzo ephezulu.
Yini Okufanele Uyicabangele Lapho Ukhetha Isiphindaphindi Sesiginali Yeselula?
Ukuqonda lezi zinhlaka ezimbili kusiza ekukhetheni isiphindaphinda sesiginali yeselula esifanele izinhlelo zokusebenza ezithile:
1. Gxila kumabhendi amafrikhwensi adinga ukukhuliswa. Amabhendi asetshenziswa kakhulu namuhla afaka i-GSM, LTE, DSC, WCDMA, ne-NR. Ungaxhumana nenkampani yakho yenethiwekhi ukuze uthole ulwazi, noma uhlole amabhendi esignali yeselula usebenzisa izindlela ezinikezwe ngezansi.
2. Khomba indawo enesignali yokwamukela kahle, futhi usebenzise ifoni yakho nesofthiwe yokuhlola ukukala amandla esignali. Abasebenzisi be-iPhone bangathola okokufundisa okulula nge-Google, kuyilapho abasebenzisi be-Android bengalanda uhlelo lokusebenza lwe-Cellular Z esitolo sohlelo lokusebenza ukuze luhlolwe isignali.
I-RSRP (Reference Signal Received Power) isilinganiso esijwayelekile sokuhlola ukushelela kwesignali. Ngokuvamile, amanani angaphezu kuka-80 dBm abonisa ukwamukela okushelela kakhulu, kuyilapho amanani angaphansi kuka -110 dBm ebonisa cishe akukho ukuxhumana kwenethiwekhi. Ngokuvamile, kufanele uhlose umthombo wesignali ongezansi -100 dBm.
3. Khetha isiphindaphindi sesignali yeselula esifanele ngokusekelwe kumandla esignali nendawo edinga ukufakwa.
Ngokuvamile, uma ibanga eliphakathi komthombo wesignali nendawo embozwayo eqondiwe lilikhulu, ukuncipha okubangelwa ikhebula kuzoba phezulu, okudinga ophindayo ngenzuzo enkulu.
Ukuze uthole ukumbozwa okubanzi kwamasignali eselula, kufanele ukhethe ukuphinda isiginali yeselula enamandla amakhulu.
Uma ungaqiniseki ukuthi iyiphi i-signer yesiginali yeselula ongakhetha ukuyikhetha,sicela usithinte, futhi sizokunikeza isisombululo sokumboza isignali yeselula ngokushesha ngangokunokwenzeka.
I-Lintratekube ngumkhiqizi ochwepheshile wezokuxhumana ngeselula ngemishini ehlanganisa i-R&D, ukukhiqiza, nokuthengisa iminyaka eyi-12. Imikhiqizo yokumboza isignali emkhakheni wezokuxhumana ngomakhalekhukhwini: izithuthukisi zesiginali yeselula, izinti, izihlukanisi zamandla, ama-couplers, njll.
