Ubuchwepheshe bokukhanya okukhanya bukwakha imiqondo ye-Wi-Fi ukudlulisa idatha ngokushesha
I-Li-Fi yinqubo yokudlulisa ulwazi ngokusheshisa kakhulu. Esikhundleni sokusebenzisa izimpawu zomsakazo ukuze uthumele ulwazi - yilokho okusetshenziselwa i -Wi-Fi - Ubuchwepheshe bokukhanya okukhanya, okuvame ukubizwa nge-Li-Fi, kusebenzisa ukukhanya kwe- LED ebonakalayo.
Yakhiwe nini i-Li-Fi?
I-Li-Fi idalwe njengenye indlela kumathuluzi wenethiwekhi asekelwe kumvamisa womsakazo (RF) . Njengoba ukuxhumana okungaxhunyiwe ku-intanethi kuqhumekile ekuthandeni, sekuye kwaba nzima kakhulu ukuthwala lezi zimali ezinkulu zedatha ngenani elinganiselwe lamaqembu omvuthwandaba omsakazo atholakalayo.
UHarald Hass, umcwaningi eYunivesithi yase-Edinburgh (eScotland), ubizwa ngokuthi uBaba weLi-Fi ngemizamo yakhe ekuthuthukiseni lobu buchwepheshe. Inkulumo yakhe ye-TED ngo-2011 yaletha i-Li-Fi kanye neProjekthi ye-D-Light yeYunivesithi embonweni womphakathi okokuqala, eyibiza ngokuthi "idatha ngokukhanya."
I-Li-Fi ne-Visible Light Communication (VLC) Umsebenzi
I-Li-Fi yindlela yeVisible Light Communication (VLC) . Ukusebenzisa izibani njengamadivaysi okuxhumana akuyona umqondo omusha, osukho eminyakeni engaphezu kwengu-100. Nge-VLC, izinguquko ekujuleni kokukhanyisa zingasetshenziselwa ukuxhumana ngolwazi olufakiwe.
Amafomu okuqala e-VLC asebenzisa izibani zendabuko zendabuko kodwa akakwazanga ukufeza amazinga aphezulu kakhulu wedatha. IEEE iqembu labasebenzi 802.15.7 liyaqhubeka nokusebenza kumazinga omkhakha we-VLC.
I-Li-Fi isebenzisa ama-diode amhlophe okukhanyisa ama-LED (ama-LED) kunokuba i-fluorescent yendabuko noma ama-incandescent ama. Inethiwekhi ye-Li-Fi iyashintsha ubukhulu be-LED phezulu futhi phansi phansi ngesivinini esiphezulu kakhulu (ngokushesha kakhulu ukuze iso lomuntu liqonde) ukudlulisa idatha, uhlobo lwekhodi ye-hyper-speed speed.
Ngokufanayo namanethiwekhi we-Wi-Fi, ama-Li-Fi adinga amaphuzu wokufinyelela e-Li-Fi akhethekile ukuhlela ithrafikhi phakathi kwamadivayisi. Amadivayisi womthengi kufanele akhiwe nge-adapter ye-Wireless ye-Li-Fi, noma i-chip eyakhelwe ngaphakathi noma i- dongle .
Izinzuzo ze-Li-Fi Technology Ne-intanethi
Amanethiwekhi e-Li-Fi agwema ukuphazamiseka kwemvamisa yomsakazo, ukucatshangelwa okubaluleke kakhulu emakhaya njengoba ukuthandwa kwe- Inthanethi yezinto (i-IoT) namanye amagajethi angenawaya aqhubeka nokwanda. Ukwengeza, inani le- spectrum engenazintambo (ububanzi bemikhawulo yesignali etholakalayo) ngokukhanya okubonakalayo kudlulele kakhulu kweyomsakazo we-radio njengaleyo esetshenziselwa i-Wi-Fi - izimangalo ezibalwe ngokuphindaphindiwe izikhathi ezingu-10 000. Lokhu kusho ukuthi amanethiwekhi we-Li-Fi kufanele athole inzuzo enkulu ngaphezu kwe-Wi-Fi ekukhoneni kwamanethiwekhi okusekela nge traffic eziningi.
Amanethiwekhi e-Li-Fi akhiwe ukuze asetshenziswe ukukhanya okufakiwe kakade emakhaya nakwezinye izakhiwo, okwenza kube eshibhile ukufaka. Zisebenza kakhulu njengamaxhunyiwe we- infrared asebenzisa ama-wavevel of light engabonakali emehlweni e-human, kodwa i-Li-Fi ayidingi ama-transmitter ahlukene alula.
Ngenxa yokuthi ukuhanjiswa kuvinjelwe ezindaweni lapho ukukhanya kungena khona, i-Li-Fi inikeza inzuzo yokuvikeleka yemvelo phezu kwe-Wi-Fi lapho izimpawu kalula (futhi ngokuvamile ngokuklama) zihamba ngezindonga nasemhlabathini.
Labo ababaza imiphumela yempilo ye-Wi-Fi yokudalwa isikhathi eside kubantu bazoyithola i-Li-Fi inketho engezansi.
Ukushesha kangakanani i-Li-Fi?
Ukuhlolwa kwelabhu kubonisa ukuthi i-Li-Fi ingasebenza ngokusheshisa okukhulu kwezinto; ukuhlolwa okukodwa kulinganise izinga lokudluliswa kwedatha lama-224 Gbps (ama-gigabits, hhayi ama-megabits). Ngisho nalapho izinto ezisebenzayo ze- network protocol ngaphezulu (njenge- encryption ) zicatshangelwa, i-Li-Fi iyashesha kakhulu.
Izinkinga ezine-Li-Fi
I-Li-Fi ayikwazi ukusebenza kahle ngaphandle kokuphazamiseka kwelanga. Ukuxhumanisa kwe-Li-Fi nakho akunakwenzeka ukungena ezindongeni nezinto ezivimba ukukhanya.
I-Wi-Fi isivele ijabulela isisekelo esikhulu esimisiwe samanethiwekhi wekhaya namabhizinisi emhlabeni jikelele. Ukwandisa ukuthi yiziphi izinhlinzeko ze-Wi-Fi kudinga ukunikeza abathengi isizathu esicindezelayo sokuthuthukisa futhi ngezindleko eziphansi. Izifunda ezengeziwe okumelwe zengezwe kuma-LED ukuze zikwazi ukuxhumana nabo nge-Li-Fi kufanele zamukelwe abakhiqizi be-bulb ezinkulu.
Ngenkathi i-Li-FI ijabule imiphumela emihle yokuhlolwa kwelebhu, kungase kube khona iminyaka ukuthi ingabikho kakhulu kubathengi.
