Ezweni lanamuhla, isignali yeselula isiyingxenye ebalulekile yokuphila kwethu kwansuku zonke. Ukuthi ukushaya izingcingo, ukuthumela imibhalo, noma ukuphequlula i-inthanethi, ukuxhumana okuzinzile kwesignali kubalulekile. Nokho, 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 Esiginali vs. Ikhwalithi Yesiginali: Uyini Umehluko?
Amandla Esignali
Amandla esignali abhekisela emandleni esignali atholwe iselula yakho esuka esiteshini, ngokuvamile akalwa ngama-decibel milliwatts (dBm). Lapho inani lamandla esignali liphakeme, isignali iba namandla; inani eliphansi, isignali iba buthakathaka. Izinto ezithinta kakhulu amandla esignali zihlanganisa:
-Ibanga elisuka esiteshini: Uma ukude nesiteshi, isignali iba buthakathaka.
-Izithiyo: Izakhiwo, izintaba, izihlahla, nezinye izithiyo zinganciphisa isignali.
-Izimo Zesimo Sezulu: Isimo sezulu esibi, njengemvula enkulu noma iqhwa, singaphazamisa amandla esignali.
Ikhwalithi Yesiginali
Ikhwalithi yesiginali isho ukucaca nokuzinza kwesignali, ngokuvamile ikalwa ngamapharamitha afana ne-Signal-to-Noise Ratio (SNR) kanye ne-Bit Error Rate (BER). Izinga lesiginali lithinta ngokuqondile ukucaca kwekholi nokuzinza kokudluliswa kwedatha. Izinto ezithonya ikhwalithi yesiginali zihlanganisa:
-Ukuphazamisa: Ukuphazamisa okuvela kumishini kagesi, izintambo zikagesi, namanye amasignali angenantambo kungehlisa izinga lesignali.
-Ukuminyana Kwenethiwekhi: Ngesikhathi samahora aphezulu noma ezindaweni ezinabantu abaningi, ukuminyana kwenethiwekhi kungaholela kukhwalithi yesignali ephansi.
-Umphumela we-Multipath: Uma isignali ihlangabezana nokuboniswa noma ukuphikiswa ngesikhathi sokudlulisa, kungaholela ekwehleni kwekhwalithi yesiginali.
Ungawakala Kanjani Amandla Esiginali Yeselula Nekhwalithi?
Ungakwazi ukukala amandla esignali yakho yeselula kanye nekhwalithi usebenzisa uhlelo lokusebenza olubizwa ngokuthi “Cellular-Z,” olutholakala kumakethe yohlelo lokusebenza lwe-Android. Ngokuvula uhlelo lokusebenza, ungabheka isimo sesiginali endaweni yangakini.
Amandla Esignali
-RSRP Inani > -80 dBm: Amandla esignali amahle kakhulu.
-RSRP Value > -100 dBm: Amandla esignali amahle.
-RSRP Value < -100 dBm: Amandla esignali angenamandla.
Njengoba kuboniswe esithombeni esingezansi, inani le-RSRP lika -89 libonisa amandla esignali amahle.
Ikhwalithi Yesiginali
-SINR Inani > 5: Ikhwalithi yesignali enhle.
-SINR Inani eliphakathi kuka-0-5: Isiginali ibhekene nokuphazamiseka okuthile.
-Inani le-SINR < 0: Isiginali iphazamiseke kakhulu.
Njengoba kuboniswe esithombeni esingezansi, inani le-SINR le-15 libonisa ikhwalithi yesignali enhle kakhulu.
Ungawathuthukisa Kanjani Amandla Esiginali Yeselula Nekhwalithi?
Kokubili amandla esignali kanye nekhwalithi yesignali kubalulekile ekuthuthukiseni isignali yakho yeselula. Amandla esiginali anquma ukuthi ungakwazi yini ukuthola isignali, kuyilapho ikhwalithi yesiginali iqinisekisa ukuthi ungasebenzisa leyo siginali ngokwethembeka.
Kulabo abafuna ukuthuthukisa isignali yabo yeselula, ukusebenzisa i-booster yesignali yeselula kuyisixazululo esiphelele nesinokwethenjelwa sokubhekana nakho kokubili amandla esignali nezinkinga zekhwalithi.
I-Lintratek, onolwazi lweminyaka engaphezu kwe-13 ku-i-booster yesignali yeselulaimboni, inikeza uhla olugcwele lwemikhiqizo, kusukela kuma-booster esignali asekhaya anamandla aphansi kuya kwebanga lezentengisoi-fiber optic repeaters. Noma ngabe ufuna izixazululo zendawo yokuhlala, yezohwebo, noma yezimboni, i-Lintratek inikeza izixazululo ezingcono kakhulu zokufakwa kwesignali yeselula.
