Kutheni iselfowuni ingasebenzi xa isignali igcwele?

Isizathu 1: Ixabiso lefowuni ephathwayo alichanekanga, akukho signali kodwa libonisa igridi epheleleyo?

1. Kwinkqubo yokwamkela nokuthumela iisignali, ifowuni ephathwayo inetshiphu ye-baseband yokufaka ikhowudi kunye nokususa isignali. Ukuba ukusebenza kakuhle kwe-chip akusebenzi kakuhle, isignali yefowuni ephathwayo iya kuba buthathaka.

2. Uhlobo ngalunye lwefowuni ephathwayo alunamithetho ifanayo kumgangatho wegridi yesignali, kwaye ezinye iimpawu ziya kwehlisa ixabiso ukuze kubonakale "uphawu lulungile", ngoko ke uphawu lokubonisa lwefowuni ephathwayo lugcwele, kodwa isiphumo esisebenzayo asisihle.

Isizathu sesi-2: Ukusasazwa kwesignali yempembelelo kokusingqongileyo, okubangela "amabala angabonakaliyo".

Amaza e-electromagnetic asasazeka kwicala elilawulwa yi-antenna, kwaye imiqobo ethintela ukusasazeka kwamaza e-electromagnetic, njengeegobolondo zesinyithi zeemoto noololiwe, iiglasi zezakhiwo kunye neminye imiqobo enokungena, iya kuyinciphisa isignali yefowuni ephathwayo. Ukuba ikwigumbi elingaphantsi okanye ilifti, indawo ayinkulu okanye isemaphethelweni esithintelo, amaza e-electromagnetic esithintelo kunzima ukungena kuwo okanye ayinakuyiphazamisa, ifowuni ephathwayo isenokungabi nasignali konke konke.

Umgangatho wokulinganisa amandla eSignali yefowuni ephathwayo ubizwa ngokuba yi-RSRP (Amandla okufumana iSignali yeReference). Iyunithi yesignali yi-dBm, uluhlu luyi--50dBm ukuya kwi--130dBm, kwaye okukhona ixabiso elipheleleyo lincinci, kokukhona isignali inamandla ngakumbi.

Ifowuni ephathwayo enenkqubo ye-IOS: Vula ikhibhodi yokudayela yefowuni ephathwayo – faka *3001#12345#* – Cofa iqhosha elithi [Call] – Cofa [serving CELL info] – Fumana i-[RSRP] kwaye ujonge amandla esignali echanekileyo yefowuni ephathwayo.

Ifowuni ephathwayo enenkqubo ye-Androidbhala ifowuni [Izicwangciso] – Cofa [Malunga nefowuni] – cofa [Umyalezo Wesimo] – cofa [Inethiwekhi] – Fumana [Amandla esignali] uze ujonge ixabiso elichanekileyo lamandla esignali yangoku yefowuni.

Ngokuxhomekeke kwimodeli yefowuni kunye nenkampani ethwala ifowuni, kunokubakho umahluko kwindlela esebenza ngayo. Ezi ndlela zingasentla zenzelwe ukubhekisa kuphela.
