I-Antenna yangaphandle 470-510MHz ethi Flexible whip
Isingeniso Somkhiqizo
I-470-510MHz i-flexible whip antenna iyi-antenna yokuxhumana engenantambo esebenza kahle kakhulu.Isebenzisa isixhumi sowesilisa se-SMA ukwenza lula ukuxhumana namadivayisi ahlukahlukene futhi ifanele ukusetshenziswa ezindaweni ezingaphandle.Ukusebenza kahle kwemisebe ye-antenna kufinyelela ku-53%, okusho ukuthi ingaguqula ngempumelelo amandla kagesi abe amandla asakazwayo futhi inikeze ukudluliswa kwesignali okuzinzile.Ngesikhathi esifanayo, ukuzuza kwayo okuphezulu kudlula i-1 dBi futhi inamandla okuthuthukisa isignali aqinile, anganweba ububanzi bokuxhumana.
Le antenna isetshenziswa kakhulu ezimeni ezehlukene, okuhlanganisa i-smart metering, amasango, ukuqapha okungenantambo namanethiwekhi anezikhala.Emkhakheni we-smart metering, ingasetshenziswa ukuxhumana namamitha kagesi ahlakaniphile, amamitha amanzi nezinye izinto zokusebenza ukuze kuzuzwe ukuqoqwa kwedatha okuhlakaniphile nokuqapha okukude.Ngokuya ngamasango, ingaxhuma namadivayisi ahlukahlukene wesango ukuze inikeze ukwesekwa kokuxhumana okungenantambo okuzinzile.Kuzinhlelo zokusebenza zokugada okungenantambo, ingasetshenziselwa ukudlulisa isignali yamakhamera okuqapha ividiyo nezinye izinto zokusebenza ukuze kuqinisekiswe ikhwalithi yevidiyo nokuzinza.Kunethiwekhi ye-mesh, ingasetshenziswa njengendawo yokuxhumana phakathi kwamadivayisi e-node ukuze kubonwe ukushintshana kwedatha nomsebenzi wokuhlanganyela phakathi kwamadivayisi.
I-antenna inephethini yokudlulisela phambili ye-omnidirectional enhle kakhulu, okusho ukuthi ikhipha amasignali ngokulinganayo kuzo zonke izinhlangothi, inikeza ukumboza okubanzi.Lokhu kuyenza ifanelekele izinhlelo zokusebenza ezidinga ukufakwa ezindaweni ezinkulu, njengezakhiwo ezinkulu, izindawo zasemadolobheni, njll. Kungakhathaliseki ukuthi ingaphakathi noma ngaphandle, le-antenna inganikeza ukusekela kokuxhumana okungenantambo okuzinzile nokusebenzayo.
