Kungani iselula ingakwazi ukusebenza lapho isignali iyizinsimbi ezigcwele?

Isizathu 1: Inani leselula alinembile, alinasiginali kodwa libonisa igridi egcwele?

1. Enqubweni yokwamukela nokuthumela amasignali, ifoni ephathekayo ine-baseband chip ukuze ihlanganise futhi inqume isignali. Uma ukusebenza kahle kwe-chip kungalungile, isignali yeselula izoba buthakathaka.

2. Ibhrendi ngayinye yeselula ayinazo izimiso ezifanayo ezilinganisweni zegridi yesignali, futhi ezinye izinhlobo zizokwehlisa inani ukuze kugqanyiswe "isiginali yinhle", ngakho isignali yokubonisa umakhalekhukhwini igcwele, kodwa umphumela ongokoqobo awulungile.

Isizathu sesi-2: Ukusabalalisa isignali yomthelela wendawo, okuholela “ezindawo eziyimpumputhe”.

Amagagasi kagesi asakazeka lapho elawulwa khona uthi, futhi izithiyo ezivimbela ukusatshalaliswa kwamagagasi kagesi, njengamagobolondo ensimbi ezimoto nezitimela, ingilazi yezakhiwo nezinye izithiyo ezingangenwa kuzo, zizonciphisa isignali yeselula. Uma isendaweni engaphansi noma i-elevator, indawo ayinkulu noma emaphethelweni esithiyo, igagasi le-electromagnetic lesithiyo linzima ukungena noma alikwazi ukuhlukanisa, ifoni ephathekayo ingase ingabi nayo isignali nhlobo.

Izinga lokulinganisa amandla eSiginali yeselula libizwa nge-RSRP(Reference Signal Receiving Power). Iyunithi yesiginali ingu-dBm, ububanzi bungu-50dBm ukuya ku--130dBm, futhi uma lincane inani eliphelele, isignali inamandla.

Iselula enohlelo lwe-IOS: Vula ikhibhodi yokudayela yeselula – faka *3001#12345#* – Chofoza inkinobho ethi [Shaya] – Chofoza [ukunikeza ulwazi lwe-CELL] – Thola i-[RSRP] bese ubuka amandla esiginali aqondile weselula .

Ifoni ephathekayo enesistimu ye-Androidbhala ifoni [Izilungiselelo] – Chofoza [Mayelana nefoni] – chofoza [Umlayezo Wesimo] – chofoza [Inethiwekhi] – Thola [Amandla esignali] futhi ubuke inani eliqondile lamandla esignali yamanje yefoni.

Ngokuya ngemodeli yefoni kanye nenkampani yenethiwekhi, kungase kube nomehluko ekusebenzeni. Izindlela ezingenhla ngezereferensi kuphela.
