Uzoba nentshisekelo yokwazi Usebenza kanjani ophindayo we-WifiKulesi sihloko sizokunikeza yonke imininingwane nezincomo ezidingekayo ngokushesha futhi kalula.
Usebenza kanjani umuntu ophindayo?
Esikhathini samanje ama-routers anesibopho sokukhipha amasiginali avela kwamanye amadivayisi we-decoder abizwa nge-Modem.Lokhu kuphuma kubizwa nge-Wifi futhi basebenzela ukusungula ukuxhumana okungenawaya kumadivayisi ahlukahlukene eselula, amaphrinta, amaphilisi, amathelevishini namakhompyutha.
Kepha kukhona namasu okwandisa ukufakwa endaweni lapho la maqembu etholakala khona. Ubuchwepheshe banamuhla buxhomeke kakhulu ekuxhumaneni okungenantambo kwe-Wi-Fi, ubumnandi, umsebenzi kanye nobuchwepheshe obuningi busebenzisa lezi zimpawu ukwenza imisebenzi yabo; Kungakho namuhla kule ndatshana sizogxila kwisici esichazayo nesobuchwepheshe, ukukhombisa umfundi ukuthi osebenza kanjani uphinda asebenze kanjani.
Descripción
Lawa madivayisi ahlukile asebenza ngokubambisana nama-PLC ukuze athuthukise isignali ye-Wi-Fi. Ziyimishini elula yokuthi ngokubonakala kwayo kungabonakala sengathi ukusebenza nokufakwa kwakunzima kakhulu. Kodwa-ke, njengoba uzobona ngezansi, izinqubo azilutho ongabhalela ekhaya ngazo.
Bakulungele ukunweba lokho okubizwa ngokuthi inethiwekhi yasekhaya, esetshenziswa ngabantu abaningi namabhizinisi kodwa eyaziwa ngabambalwa. Ngale nethiwekhi ungafinyelela inani elingalindelekile lezicelo kanye nokwenziwa kwemisebenzi; kodwa masingaphambuki.
Abaphindayo bafuna ukuxhuma amasiginali we-inthanethi ngendlela efanayo nokuxhuma kwentambo. Umqondo wukwandisa ukudluliswa futhi uvikele ukuphazamiseka okukhiqizwa ngamanye amadivayisi ahambisa amasiginali kagesi.
Ngakho-ke usebenza kanjani umuntu ophindayo?
Ngokomthetho singasho ukuthi bafuna ngokusebenzisa amapharamitha athile ukuze babambe isignali yenethiwekhi ye-Wi-Fi onayo ekhaya noma ehhovisi lakho. Bese uyidlulisa ngekhwalithi engcono futhi uqhubekele phambili kancane kunamakhava omthamo we-router, ulibhekise ebangeni eliphindwe kabili noma kathathu ebangeni elizokwenziwa yilokhu; lawa madivayisi asebenzisa iphasiwedi efanayo nezilungiselelo zedivayisi eyisisekelo.
Bese baba uhlobo lwebhuloho ngobude obukhulu. Lapho banikela khona ngobubanzi obukhulu nebanga elingaphezulu, lokwelula isignali ezindaweni ezikude kakhulu. Ukwenza lokhu, isebenzisa uchungechunge lwezimpondo zomthamo ophakeme futhi luzidlulisele ezindaweni ezikude kakhulu zendlu.
Omunye umsebenzi ofanele ngukuthi ukudluliswa kwenziwa kuzo zonke izinkomba, okungukuthi, ngokungafani nalezo ezinikezwe umzila wendabuko, amasiginali ophindayo anwetshwa ngobukhulu obukhulu, ngaleyo ndlela kuvumela igagasi ukuba landiswe futhi linikeze isiginali eyandisiwe.
La maqembu angakwazi ukukhulisa amanethiwekhi asekhona ngezandiso ezisebenzisela ukudala inethiwekhi yazo ezimele ye-Wi-Fi. Ngisho nokuba negama nephasiwedi yakho ehluke ngokuphelele; ngakho-ke, ukucupha okufanele kwenziwe kudivayisi ngayinye exhunywe eduze kwendawo.
Ukusebenza
Izinsiza zalolu hlobo zenzelwe ukwenza nokusebenza lapho zithola isignali ye-Wi-Fi. Ukusebenza kwayo kulula; Iziphindayo zenziwa ngama-routers wohlobo olungenazintambo, lapho omunye wabo enesibopho sokwamukela isignali ekhishwa yi-router bese eyiguqula bese eyithumela kumzila olandelayo.
Le enye i-router yakhiwe ngezinto lapho ungathumela futhi uphindaphinde isignali ngamandla amaningi, isenze sifinyelele emakhoneni anzima kakhulu nasezindaweni ezinzima kakhulu ezindaweni ezahlukahlukene. Ngalokhu, ukumbozwa okukhulu kutholakala futhi izakhi eziningi zingaxhunywa ngasikhathi sinye ngaphandle kokunciphisa ikhwalithi yazo.
Izici zophindayo
Lawa madivayisi awusizo kakhulu lapho udinga ukusebenzisa izinsiza ezanele ze-inthanethi, ikakhulukazi uma unanoma iyiphi inombolo yamadivayisi namakhompyutha endaweni enkulu. Bacabanga ukuthi kufanele bafake ucingo. Isibonelo, lapho ihhovisi linamakhompyutha angaphezu kwama-60 endaweni ecishe ibe yi-120 m2.
Kungaba yindawo yokuhlanya lapho kufanele uphathe ukuxhumana okuningi kangaka bese uzama ukugcina izinga lokusebenza ngendlela efaneleke kakhulu. Kepha hhayi lokho kuphela, ukufakwa kukhebula kaningi kudala ukushisa nokuvinjelwa kokuthunyelwayo lapho kuxhunywe kuseva.
Ngenxa yalokho, ukusebenza ngobuchwepheshe obuphakeme njengokuphindayo, ukusebenza okuthe xaxa kuyatholakala. Ukugwema ukudideka ekuxhumaneni ngakunye nokukhiqiza ukusetshenziswa kwamandla amancane nezindleko; Kodwa-ke, phakathi kwezinye izici ezibalulekile singabala okulandelayo:
- Ngokuya ngemodeli yokuphindayo, nweba amagagasi aze afike cishe ku-500 m (Iningi lama-routers angafinyelela ebangeni eliphakeme lamamitha angama-30, uma okokusebenza kusezingeni eliphezulu).
- Ivuselela amasiginali futhi ikhulise kahle ngaphandle kokulahlekelwa yinoma yiliphi ikhwalithi yokudluliselwa kweWifi.
- Uma uthola igatsha elimpofu, unamandla okulihlukanisa, ngokwesibonelo lapho kunezintambo ezivulekile.
- Ingaguqula imidiya ehlukahlukene enjenge-Ethernet, ekhiqizwa nge-fiber optics, kanye nokuxhumana kohlobo lwe-coaxial, Thick Ethernet to Thin Ethernet
Izinhlobo
Kunamamodeli amaningi angathengwa emakethe ngokuya ngezidingo zamakhasimende. Kukhona namakhulu wemikhiqizo ekhiqiza ngobuningi lawa madivayisi, kepha ezingeni elijwayelekile singasho ukuthi kukhona okulandelayo.
Multiport Repeater
Isetshenziswa emahhovisi aneminyango engamakhulu futhi ivumela amagatsha amaningana ukuthi athwalelwe ku-185 m. Kanye nokusabalalisa kusuka kwikhebula le-coaxial noma ikhebula le-fiber optic elilula elinemisebenzi yokuhlukanisa ethekwini ngalinye.
Ukuphindaphinda okukodwa
Isetshenziswa ezindaweni ezincane kuze kufike ku-100 m. bakhiqiza ikhwalithi yesiginali efanayo njengama-routers noma ukuxhumana okuqondile kwekhebula, imisebenzi ye-fiber optic, i-AUI, phakathi kwezinye izindlela, iyasungulwa.
Umehluko osuka kuma-PLC
I-PLC noma i-Programmable Logic Controller, (i-Programmable Logic Controller, isifinyezo sayo esiNgisini), yiprosesa esetshenziselwa ubunjiniyela be-automation ukwenza umsebenzi kumishini nemishini. Uhlelo lunikeza ukuzimela okuncane futhi benza imisebenzi eqondile nehleliwe, bayasetshenziswa ekukhiqizeni imikhiqizo nasembonini yokukhiqiza.
Abaningi bazamile ukuqhathanisa amasistimu ala ma-PLC nabaphindayo, kepha njengoba sibona ukuthi kunomsebenzi wokugcina ohluke ngokuphelele. Ngaphakathi banesakhiwo esifanayo maqondana ne-elekthronikhi, ikakhulukazi lapho bethola imininingwane yangaphandle futhi kufanele bayicubungule.
Zombili lezi zinhlelo zinesibopho sokuthumela imininingwane echazwe ngokusebenza kwemishini. Endabeni yabaphindayo, umsebenzi uthunyelwa ngendlela yesiginali, ngaphambili wawutholwa futhi wenyuselwa ekuhambeni kwesikhathi uyiswe kwamanye amadivayisi.
Manje njengoba usuyazi ukuthi umuntu ophindayo usebenza kanjani, ungashiya umbono wakho bese usinika owakho umbono, ngendlela efanayo sincoma ukuthi ufunde i-athikili elandelayo Izinhlobo zamanethiwekhi e-LAN lapho uzothola khona imininingwane eyengeziwe ehlobene nalesi sihloko.
