Kungani ifoni ingasebenzi uma isignali igcwele amabha?

Isizathu 1: Inani lefoni ephathekayo alinembile, alinawo amasignali kodwa libonisa igridi egcwele?

1. Enkambisweni yokwamukela nokuthumela amasignali, ifoni ephathekayo ine-chip ye-baseband yokufaka ikhodi nokuhlela isignali. Uma ukusebenza kahle kwe-chip kukubi, isignali yefoni ephathekayo izoba buthaka.

2. Uhlobo ngalunye lweselula alunazo izimiso ezifanayo ezindinganisweni zegridi yesignali, futhi ezinye izinhlobo zizokwehlisa inani ukuze kugqanyiswe ukuthi "isignali ilungile", ngakho-ke isignali yokubonisa ifoni ephathekayo igcwele, kodwa umphumela osebenzayo mubi.

Isizathu sesi-2: Ukusabalala kwesignali yomthelela endaweni, okuholela “ezindaweni ezingaboni”.

Amagagasi kagesi asakazeka ngendlela elawulwa yi-antenna, kanti izithiyo ezivimbela ukusabalala kwamagagasi kagesi, njengemigoqo yensimbi yezimoto nezitimela, ingilazi yezakhiwo nezinye izithiyo ezingangena, zizonciphisa isignali yocingo oluphathwayo. Uma ingaphansi noma ilifti, indawo ayinkulu noma isemaphethelweni esithintelo, igagasi kagesi locingo oluthiyayo kunzima ukulingena noma alikwazi ukuliphazamisa, ifoni ingase ingabi nasignali nhlobo.

Izinga elijwayelekile lokukala amandla eSignali yocingo oluphathwayo libizwa ngokuthi i-RSRP (Amandla Okwamukela Isignali Yereferensi). Iyunithi yesignali yi-dBm, ububanzi buyi--50dBm kuya ku--130dBm, futhi uma inani eliphelele lincane, isignali iqina kakhulu.

Ifoni ephathekayo enesistimu ye-IOS: Vula ikhibhodi yokudayela yefoni ephathekayo – faka *3001#12345#* – Chofoza inkinobho ethi [Call] – Chofoza [serving CELL info] – Thola i-[RSRP] bese ubheka amandla esignali aqondile efoni ephathekayo.

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

Kuye ngemodeli yefoni kanye nenkampani yenethiwekhi, kungase kube nomehluko ekusebenzeni. Izindlela ezingenhla zingezokubhekisela kuphela.
