Umehluko Phakathi Kwamandla Esignali Yeselula Nekhwalithi Yesignali

Ezweni lanamuhla, isignali yeselula isibe yingxenye ebalulekile yempilo yethu yansuku zonke. Kungakhathaliseki ukuthi ushaya izingcingo, uthumela imiyalezo, noma uphequlula i-inthanethi, ukuxhumana kwesignali okuzinzile kubalulekile. Kodwa-ke, abantu abaningi bavame ukudida amagama athi “amandla esignali” kanye “nekhwalithi yesignali.” Kulesi sihloko, sizocacisa le mibono futhi sikusize uqonde kangcono umehluko phakathi kwamandla esignali yeselula kanye nekhwalithi yesignali.

Amandla Esignali vs. Ikhwalithi Yesignali: Uyini Umehluko?

Amandla Esiginali

Amandla esignali abhekisela emandleni esignali atholwa yifoni yakho ephathekayo esuka esiteshini sesisekelo, ngokuvamile alinganiswa ngama-decibel milliwatts (dBm). Uma inani lamandla esignali liphakeme, isignali iqina; uma inani liphansi, isignali iba buthaka. Izici ezithinta kakhulu amandla esignali zifaka:
-Ibanga ukusuka eSiteshini Esiyisisekelo: Uma ukude nesiteshi esiyisisekelo, isignali iba buthaka.
-Izithiyo: Izakhiwo, izintaba, izihlahla, nezinye izithiyo zinganciphisa isignali.
-Izimo Zesimo Sezulu: Isimo sezulu esibi, njengemvula enkulu noma iqhwa, singathinta namandla esignali.

Ikhwalithi Yesignali

Ikhwalithi yesignali ibhekisela ekucaceni nasekuzinzeni kwesignali, ngokuvamile kulinganiswa ngamapharamitha afana neSignal-to-Noise Ratio (SNR) kanye neBit Error Rate (BER). Ikhwalithi yesignali ithinta ngqo ukucaca kwezingcingo kanye nokuqina kokudluliswa kwedatha. Izici ezithonya ikhwalithi yesignali zifaka:
-Ukuphazamiseka: Ukuphazamiseka okuvela kumadivayisi kagesi, izintambo zikagesi, kanye nezinye izimpawu ezingenantambo kungonakalisa ikhwalithi yesignali.
-Ukuminyana Kwenethiwekhi: Ngesikhathi samahora amaningi noma ezindaweni ezinabantu abaningi, ukuminyana kwenethiwekhi kungaholela ekhwalithini yesignali ephansi.
-Umphumela Wezindlela Eziningi: Uma isignali ihlangana nokubonakaliswa noma ukugudluzwa ngesikhathi sokudluliselwa, kungabangela ikhwalithi yesignali ewohlokayo.
Ungalinganisa Kanjani Amandla Nekhwalithi Yesignali Yeselula?

Ungalinganisa amandla esignali yakho yeselula kanye nekhwalithi usebenzisa uhlelo lokusebenza olubizwa ngokuthi “Cellular-Z,” olutholakala emakethe yezinhlelo zokusebenza ze-Android. Ngokuvula nje uhlelo lokusebenza, ungahlola isimo sesignali endaweni yakini.
Amandla Esiginali
-Inani le-RSRP > -80 dBm: Amandla esignali amahle kakhulu.
-Inani le-RSRP > -100 dBm: Amandla esignali amahle.
-Inani le-RSRP < -100 dBm: Amandla esignali aphansi.
Njengoba kuboniswe esithombeni esingezansi, inani le-RSRP elingu--89 libonisa amandla amahle esignali.

Ikhwalithi Yesignali
-Inani le-SINR > 5: Ikhwalithi yesignali enhle.
-Inani le-SINR eliphakathi kuka-0-5: Isignali ibhekene nokuphazamiseka okuthile.
-Inani le-SINR < 0: Isignali iphazamiseke kakhulu.
Njengoba kuboniswe esithombeni esingezansi, inani le-SINR elingu-15 libonisa ikhwalithi yesignali enhle kakhulu.

Ungathuthukisa Kanjani Amandla Nekhwalithi Yesignali Yeselula?

Kokubili amandla esignali kanye nekhwalithi yesignali kubalulekile ekuthuthukiseni isignali yakho yeselula. Amandla esignali anquma ukuthi ungayithola yini isignali, kuyilapho ikhwalithi yesignali iqinisekisa ukuthi ungayisebenzisa leyo signali ngokuthembekile.
Kulabo abafuna ukuthuthukisa isignali yabo yeselula, ukusebenzisa isikhuthazi sesignali yeselula kuyisisombululo esiphelele nesithembekile kakhulu sokubhekana nezinkinga zamandla esignali kanye nekhwalithi.
I-Lintratek, onolwazi olungaphezu kweminyaka eyi-13 ku-isikhuthazi sesignali yeselulaimboni, inikeza uhla oluphelele lwemikhiqizo, kusukela kuma-booster wesignali yasekhaya anamandla aphansi kuya ezingeni lokuhwebaiziphindaphindi ze-fiber opticKungakhathaliseki ukuthi ufuna izixazululo zezindawo zokuhlala, zezentengiselwano, noma zezimboni, i-Lintratek inikeza izixazululo ezinhle kakhulu zokumboza isignali yeselula.
