Kutheni i-cell phone ingasebenzi xa umqondiso ugcwele imivalo?

Isizathu 1: Ixabiso lefowuni ephathwayo ayichanekanga, akukho mqondiso kodwa ubonisa igridi epheleleyo?

1. Kwinkqubo yokufumana kunye nokuthumela iimpawu, ifowuni ephathwayo ine-baseband chip yokufaka ikhowudi kunye nokucacisa isignali. Ukuba ukusebenza kakuhle kwe-chip kubi, isignali yefowuni yeselula iya kuba buthathaka.

2. I-brand nganye yefowuni yeselula ayinayo imimiselo efanayo kumgangatho wegridi yesignali, kwaye ezinye iimpawu ziya kunciphisa ixabiso ukwenzela ukuba kugxininise "uphawu luhle", ngoko uphawu lokubonisa ifowuni lugcwele, kodwa umphumo osebenzayo awubi.

Isizathu sesi-2: Ukusasazwa komqondiso wempembelelo yokusingqongileyo, okukhokelela “kwiindawo ezingaboniyo”.

Amaza ombane asasaza kwicala elilawulwa yi-eriyali, kwaye imiqobo ethintela ukwanda kwamaza ombane, njengamaqokobhe esinyithi eemoto kunye noololiwe, iglasi yezakhiwo kunye neminye imiqobo ekunokungenwa kuyo, iya kunciphisa umqondiso wefowuni ephathwayo. Ukuba iphantsi okanye i-elevator, indawo ayinkulu okanye kumda womqobo, i-electromagnetic wave yomqobo kunzima ukungena okanye ayikwazi ukuphazamisa, ifowuni ephathwayo ayinakho uphawu kuyo yonke into.

Umgangatho wokulinganisa amandla efowuni ephathwayo Umqondiso ubizwa ngokuba yi-RSRP (Isibonakalisi sokuReference Receiving Power). Iyunithi yesiginali yi-dBm, uluhlu luyi-50dBm ukuya kwi--130dBm, kwaye incinci ixabiso elipheleleyo, isibonakaliso somelele.

Ifowuni ephathwayo enenkqubo ye-IOS: Vula ikhibhodi yokucofa kwifowuni ephathwayo – ngenisa *3001#12345#* – Cofa [Call] iqhosha – Cofa [ukusebenzela ulwazi lwe-CELL] – Fumana [RSRP] kwaye ujonge kanye amandla omqondiso wefowuni ephathwayo. .

Ifowuni ephathwayo enenkqubo ye-Androidpen ifowuni [Iisetingi] – Cofa [Malunga nefowuni] – cofa [Umyalezo Wesimo] – cofa [Inethiwekhi] – Fumana [Amandla omqondiso] kwaye ujonge elona xabiso lamandla omqondiso wangoku wefowuni.

Ngokuxhomekeke kwimodeli yefowuni kunye nomthwali, kunokubakho umahluko ekusebenzeni. Ezi ndlela zingentla zezereferensi kuphela.
