Kwihlabathi lanamhlanje, isignali yeselula ibe yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla. Nokuba ufowuna, uthumela imiyalezo, okanye ukhangela i-intanethi, uqhagamshelo oluzinzileyo lwesignali lubalulekile. Nangona kunjalo, abantu abaninzi badla ngokubhidanisa amagama athi “amandla esignali” kunye “nomgangatho wesignali.” Kweli nqaku, siza kucacisa ezi ngcamango kwaye sikuncede uqonde ngcono umahluko phakathi kwamandla esignali yeselula kunye nomgangatho wesignali.
Amandla Esignali vs. Umgangatho WeSignali: Yintoni Umahluko?
Amandla esignali
Amandla esignali abhekisa kumandla esignali afunyanwa yifowuni yakho esuka kwisikhululo sesiseko, esilinganiswa nge-decibels milliwatts (dBm). Okukhona ixabiso lamandla esignali liphezulu, kokukhona isignali inamandla; okukhona ixabiso liphantsi, kokukhona isignali ibuthathaka. Izinto ezichaphazela kakhulu amandla esignali ziquka:
-Umgama ukusuka kwiSitishi esiseSisekweni: Okukhona ukude nesitishi esiseSisekweni, kokukhona isignali ibuthathaka.
-Iingxaki: Izakhiwo, iintaba, imithi, nezinye izinto ezithintelayo zingenza isignali ibe buthathaka.
-Iimeko zeMozulu: Imozulu embi, njengemvula enkulu okanye ikhephu, inokuchaphazela amandla esignali.
Umgangatho weSignali
Umgangatho wesignali ubhekisa ekucaceni nasekuzinzeni kwesignali, edla ngokulinganiswa ziiparameter ezifana neSignal-to-Noise Ratio (SNR) kunye neBit Error Rate (BER). Umgangatho wesignali uchaphazela ngokuthe ngqo ukucaca kwefowuni kunye nokuzinza kokudluliselwa kwedatha. Izinto ezichaphazela umgangatho wesignali ziquka:
-Ukuphazamiseka: Ukuphazamiseka kwezixhobo ze-elektroniki, iintambo zombane, kunye nezinye iimpawu ezingenazingcingo kunokunciphisa umgangatho wesignali.
-Ukuxinana kweNethiwekhi: Ngexesha leeyure ezixakekileyo okanye kwiindawo ezinabantu abaninzi, ukuxinana kwenethiwekhi kunokubangela ukuba isignali ibe semgangathweni ophantsi.
-Isiphumo seendlela ezininzi: Xa isignali idibana nokubonakaliswa okanye ukurhawuzelelwa ngexesha lokudluliselwa, inokubangela ukuba umgangatho wesignali uhle.
Ungawulinganisa njani Amandla kunye noMgangatho weSignali yeSelfowuni?
Ungalinganisa amandla esignali yakho yeselula kunye nomgangatho wayo usebenzisa i-app ebizwa ngokuba yi-“Cellular-Z,” efumaneka kwimarike yee-app ze-Android. Ngokuvula nje i-app, ungajonga imeko yesignali kwindawo okuyo.
Amandla esignali
-Ixabiso le-RSRP > -80 dBm: Amandla esignali agqwesileyo.
-Ixabiso le-RSRP > -100 dBm: Amandla esignali alungileyo.
-Ixabiso le-RSRP < -100 dBm: Amandla esignali aphantsi.
Njengoko kubonisiwe kumfanekiso ongezantsi, ixabiso le-RSRP eliyi--89 libonisa amandla esignali alungileyo.
Umgangatho weSignali
-Ixabiso le-SINR > 5: Umgangatho wesignali olungileyo.
-SINR Ixabiso liphakathi kwe-0-5: Isignali ifumana ukuphazamiseka okuthile.
Ixabiso le-SINR < 0: Isignali iphazamiseke kakhulu.
Njengoko kubonisiwe kumfanekiso ongezantsi, ixabiso le-SINR eliyi-15 libonisa umgangatho ogqwesileyo wesiginali.
Ungawuphucula njani amandla kunye nomgangatho wesignali yeselula?
Amandla esignali kunye nomgangatho wesignali zibalulekile ekuphuculeni isignali yakho yeselula. Amandla esignali amisela ukuba ungayifumana na isignali, ngelixa umgangatho wesignali uqinisekisa ukuba ungayisebenzisa ngokuthembekileyo loo signali.
Kwabo bafuna ukuphucula isignali yabo yeselula, ukusebenzisa isixhobo sokunyusa isignali yeselula sesona sisombululo sibanzi nesithembekileyo sokujongana neengxaki zamandla esignali kunye nomgangatho.
I-Lintratek, unamava angaphezu kweminyaka eli-13 kweli candeloisixhasi sesignali yeselfowuniishishini, libonelela ngoluhlu olupheleleyo lweemveliso, ukusuka kwizikhulisi zesignali zasekhaya ezinamandla aphantsi ukuya kwinqanaba lorhweboiziphindaphindi ze-fiber opticNokuba ufuna izisombululo zeendawo zokuhlala, zorhwebo, okanye zoshishino, iLintratek ibonelela ngezona zisombululo zibalaseleyo zokugubungela isignali yeselula.
