Kuyini wai fay

Okokuqala, amanethiwekhi wedatha aphethwe yi-wired futhi aphansi, ama-lateral high-speed wired networks avela. Kodwa umqondo wokwakha into entsha emnandi engqondweni, futhi manje kunenethiwekhi engenantambo. Ake sibhekane nalomqondo omusha.

Ngakho-ke, yini i-wi-fi? I-Wi-Fi ihilela ukuhanjiswa kolwazi kuchwepheshe obungenawaya. Lolu hlelo lukuvumela ukuba uxhume kwinethiwekhi engenazintambo, usebenzisa izibonakaliso zomsakazo. Abantu abaningi bayazi ukuthi amagagasi omsakazo yiwona amagagasi amakhulu kunawo onke, ubude bawo bungaba bukhulu bebhola lebhola kuze kube sezingeni lebhola le -volleyball. Ngamagagasi omsakazo, amasignali adluliselwa kumamukeli womsakazo, amathelevishini, ama-terminal terminals njalonjalo.

Uma unquma ukuthi yikuphi i-wi-fi, kufanelekile ukuphawula umqondo we-node yokufinyelela. Kuqondwa ukuthi kuqondwa njenge-node eklanyelwe yenethiwekhi engenawaya yendawo, eyabelwe imisebenzi ye-transmitter ephakathi nendawo eyamukeli yale nethiwekhi. I-node yokufinyelela ngokuvamile iqukethe imishini equkethe i-antenna, umsakazo womsakazo, kanye ne- adapter yenethiwekhi ehlanganisiwe . Manje kungenzeka ukuthi ukhulume ngegama elithi Hotspot, okuyinto ejwayele ukuqonda insimu enezinombolo zokufinyelela, okuvumela iklayenti ukuba ixhume kwinethiwekhi. Insimu enjalo ingafinyeleleka ezinhlokweni ezahlukene zebhizinisi, ekhaya; I-Wi-Fi iyatholakala kakhulu emahoreni, emahhotela, amathilomu nezinye izindawo lapho kunikezwa khona mahhala noma ngemali ephansi kakhulu.

Ukuqonda lokho okushiwo, kuyafaneleka ukukusho ngeminye imibono. I-Hotspot iyinhlangano yesenzo seyodwa noma inombolo yezinombolo ezixhunyanisiwe zokufinyelela. Ingakwazi ukumboza izikhala ezahlukene. Lokhu kungaba yikamelo elincane lapho izindonga zenziwe ngomsakazo, noma indawo yamakhilomitha angama-square, lapho kutholakala amaphuzu amaningi okufinyelela. Ngale ndlela, uxhumano okuthiwa oluxubile, noma oluselula, lungalungiswa. Ngenxa yalolu buchwepheshe, uxhumano lontanga nokuya lunikezwa ukuthi ivumela amadivaysi ukuthi axhumane ngqo. Le ndlela ivame ukusetshenziswa emidlalweni yenethiwekhi, kanye nalapho isebenza ngezinhlelo zokusebenza ezihlukahlukene ze-elekthronikhi.

Inhlangano yenethiwekhi engenazintambo esiteji sokuqala yayinezinkinga eziningi ezihlobene nokusebenzisana kwamadivaysi ahlukahlukene. Emva kwalokhu, inhlangano ebizwa nge-Wi-Fi Alliance yaqala ukusebenza kule nkinga ukuhlangabezana nezidingo zabasebenzisi ngokuthuthukisa ubuchwepheshe. Uma ngabe idivayisi inesitembu "I-Wi-Fi Certified", khona-ke lesi yisiqinisekiso sabathengi ukuthi sizosebenzisana namadivayisi afanayo. Imikhiqizo enjalo iyakwazi ukusebenzisa i-noode yokungena ngokungavumelani evumela ukuxhumana namanye amadivayisi anesitifiketi esifanele.

Manje singasho ngedivayisi ye-SSID nenhloso yayo. Ukusatshalaliswa kwabo kuhlobene ngokuqondile nensizakalo yokubeka isihlonzi. Ngenxa yale khodi, kungenzeka ukuxhuma wonke amaphakethe kwinethiwekhi engenantambo. Ikhodi inamanani nezinhlamvu. Amadivaysi azama ukuxhuma omunye nomunye phezu kweziteshi ezingenantambo kumele asebenzise ikhodi efanayo. Inqubo yokuxhumana okunjalo ivame ukubizwa ngokuthi inhlangano.

Ngakho-ke, uma ungakaqondi ukuthi yiyiphi i-wi-fi, ungatshela mayelana nezingxenye ezibalulekile zamadivayisi we-Wi-Fi. Kunezici ezimbili ezibhekwa njengeziyinhloko. Lezi amadivayisi wekhompuyutha, kufaka phakathi ubuchwepheshe bomsakazo, namanethiwekhi okufinyelela amandla aphansi-axhunyiwe kunethiwekhi yendawo noma i-intanethi ngaphandle kwentambo. Baxhunyiwe phakathi kwabo ngokusebenzisa uhla lwemsakazo wamahhala, olwenziwe ngokukhethekile kubasebenzisi.
