Itheknoloji yoLungisa lokuKhanya ilwakha kwiingcamango ze-Wi-Fi ukuthumela idatha ngokukhawuleza
ULi-Fi yinkqubo yokudlulisa ulwazi ngokukhawuleza. Esikhundleni sokusebenzisa izalathisi zomsakazo ukuthumela ulwazi - yiyiphi i- Wi-Fi esebenzayo - Ubuchwephesha bokuKhanya koBhanya, okubizwa ngokuba yi-Li-Fi, isebenzisa ukukhanya kwe- LED ebonakalayo.
Kwakunjani i-Li-Fi?
U-Li-Fi wadalwa njengenye indlela kwi-network-based frequency (RF) esekelwe kobuchwephesha benethiwekhi. Njengoko unxibelelwano olungenazintambo luqhubekile ekuthandeni, kunzima kakhulu ukuphatha ezi zikhulu zedata ngenani elincinci leemvama zomsakazo ezikhoyo.
UHarald Hass, umphandi kwiYunivesithi yase-Edinburgh (eScotland), ubizwa ngokuba nguYise weLi-Fi kwimigudu yakhe ekuqhubekiseni phambili lobu bugcisa. Inkulumo yakhe ye-TED ngo-2011 yiletha i-Li-Fi kunye neprojekthi ye-D-Light yeYunivesithi ekukhanyeni koluntu okokuqala, eyibiza ngokuthi "idatha ngokukhanya."
I-Li-Fi kunye noNxibelelwano lokuKhanya kokuBonakalayo (VLC)
U-Li-Fi yindlela yoLwazi lokuKhanya lokuBonakalayo (VLC) . Ukusebenzisa izibane njengezixhobo zonxibelelwano akuyona ingcamango entsha, ehlala emva kweminyaka engama-100. Nge-VLC, utshintsho kwi-intanethi yokukhanyisa lungasetyenziselwa ukunxibelelana ngolwazi oluchanekileyo.
Iifom zokuqala ze-VLC zasebenzisa izibane zombane zendabuko kodwa zazingenakufikelela kwiziphumo eziphezulu kakhulu zedatha. IEEE esebenzayo yeqela 802.15.7 iyaqhubeka isebenza kwimigangatho yoshishino yeVLC.
U-Li-Fi usebenzisa ii-diode ezikhanyayo ezimhlophe (ii-LED) kunokuba i-fluorescent yendabuko okanye i-bulb incandescent. Inethwekhi ye-Li-Fi iguqula ubunzulu bee-LED phezulu nangaphantsi ngesantya esiphezulu kakhulu (ngokukhawuleza ukuze isohlo lomuntu liqonde) ukudlulisa idatha, uhlobo lwekhowudi ye-hyper speed speed.
Ngokufanayo ne-Wi-Fi, iinqununu ze-Li-Fi zidinga amaphulo akhethekileyo okufikelela kwi-Li-Fi ukulungiselela ukuhamba kweendlela phakathi kwezixhobo. Iifowuni zabaxhasi kufuneka zakhiwe nge-adapter ye-wireless ye-Li-Fi, nokuba i-chip eyakhelwe ngaphakathi okanye i- dongle .
Inzuzo ye-Li-Fi Technology kunye ne-Intanethi
Iinqununu ze-Li-Fi ziphephe ukuphazamiseka kwee-frequency zomsakazo, ukuxubusha okubaluleke kakhulu kumakhaya njengoko ukuthandwa kwe- Intanethi yezinto (IoT) kunye nezinye izixhobo zobuchwepheshe ezingenazintambo ziyaqhubeka zanda. Ukongezelela, isixa sembonakalo engena-wire (ububanzi bee-frequencies ezikhoyo) kunye nokukhanya okubonakalayo kunaphezulu kwee-redio njengento esetyenzisiweyo kwi-Wi-Fi-amabango amaninzi angama-10 aphezulu. Oku kuthetha iinqununu ze-Li-Fi kufuneka zithande inzuzo enkulu kwi-Wi-Fi ekukwazi ukunyuka kwiinkcukacha zonxibelelwano ezinezithuthi ezininzi.
Iinqununu ze-Li-Fi zakhiwa ukuba zisebenzise ukukhanyisa okuvele zifakwe kumakhaya nakwezinye izakhiwo, zenze ukuba zizithengise ukufaka. Basebenza ngokufana neenethwekhi zangasese ezisebenzisa ubuninzi bokukhanya okungabonakali kwiso luntu, kodwa i-Li-Fi ayifuni iifayili zokukhanya ezihlukeneyo.
Ngenxa yokuba ukuhanjiswa kuncitshiswe kwiindawo apho ukukhanya kungena khona, i-Li-Fi inikeza inzuzo yokukhusela ngokwemvelo ngaphezu kwe-Wi-Fi apho izibonakaliso kalula (kwaye ngokuqhelekileyo ngokuyila) zihamba ngeendonga kunye neepansi.
Abo baphendula ngemiphumo yempilo ye-Wi-Fi exoxa kwintlalo yabantu baya kufumana i-Li-Fi ingozi ephantsi.
Ukhawuleza kangakanani u-Li-Fi?
Iimvavanyo zeeLab zibonisa ukuba i-Li-Fi inokusebenza ngokukhawuleza kwinqanaba lokubhala; olunye uvavanyo lulinganisa izinga lokudluliswa kwedatha lama-224 Gbps (iigigabits, kungekhona i-megabits). Ngaphandle kokuba iimeko zokusebenza kwenkqubo yomnatha (njenge- encryption ) zithathwa ingqalelo, i-Li-Fi ihamba ngokukhawuleza.
Imiba eneLi-Fi
U-Li-Fi akakwazi ukusebenza ngaphandle ngaphandle kokuphazamiseka kwelanga. Ukuqhagamshelana kwe-Li-Fi kwakhona akunako ukungena kwiindonga nezinto ezivimba ukukhanya.
I-Wi-Fi sele isandula isiseko esikhulu seefayile zekhaya nakwizentengiso emhlabeni wonke. Ukwandisa kwiziphi izinikezelo ze-Wi-Fi kufuna ukuba banike abathengi isizathu esichukumisayo sokuphucula kunye neendleko eziphantsi. Iesekethe ezongezelelweyo kufuneka zifakwe kwii-LED ukwenzela ukuba bakwazi ukunxibelelana kwe-Li-Fi kufuneka bamkelwe ngabakhiqizi bamabhule.
Nangona uLi-FI uye wafumana iziphumo ezintle kwiimvavanyo zeebhanki, kusenokuba iminyaka ibe yinto yokuba ingafumaneki ngokubanzi kubathengi.
