Ganizo kulumikiza opanda zingwe Intaneti anabweretsedwa ku moyo Garoldom Haasom, ntchito pa yunivesite ya Edinburgh. Izi zinachitika mu 2011.

Asayansi ntchito owoneka kuunika kulankhulana (VLC), kutumiza deta imathamanga kwambiri mkulu. Ndipotu ntchito monga amazipanga kudya chizindikiro kuwala zikuthwanima osinthasintha kuti kupereka uthenga code bayinare (1s ndi 0s). Mu akafuna kutulukira zinthu zina pa maziko omwewo kusamutsa luso walola yekha kuti gigabits 224 pa mphindi. Yerekezerani Wi-Fi ndi kukwaniritsa imathamanga 600 megabits kwa kutalika kwa nthawi.

Kutsata zilipo

Chifukwa cha ntchito ya kampani Estonia Velmenni kunatheka amphamvu kwambiri kufala luso.

Kuwonjezera pa n'zosadabwitsa kudya kutengerapo deta Li-Fi alinso angapo ubwino pa kuloŵedwa m'malo. Mwachitsanzo, mosiyana ndi Wi-Fi, luso latsopano bwino chitetezo. Ndi kugwiritsa ntchito mbendera opatsirana ndi mtengo kuwala, kutanthauza kuti angathe kudutsa makoma, n'kusowa wosuta danga kwa adani.

Kumene, uyu adzachititsa ena mavuto. M'pofunika wosuta agogowo, iye sangathe kugwirizana kwa maukonde opanda zingwe. Komabe, ngati zopinga mu mawonekedwe a mpanda adzagonjetsedwa, Li-Fi amatsegula kwambiri mwayi. Mwachitsanzo, timatha kutumiza mauthenga pa zambiri onse pafupipafupi osiyanasiyana kuposa Wi-Fi, amene umagwira ntchito pakati pa mafurikwense wa 2.4 GHz ndi 5 GHz.

tsogolo

The Madivelopa amakhulupirira kuti Li-Fi kungakhale mmalo oyenera kwa mwachizolowezi ife luso opanda zingwe. Iwo adzalola kupewa "chotipinga" pa maukonde, amene amayamba chifukwa chakuti Internet ndi zambiri ambiri kufalitsa padziko lonse.

Malinga kuwerengetsera kuyambirira, padziko lonse mwezi deta ntchito ayenera upambana 24,3 exabytes kale ndi 2019. Ngakhale sitingathe kunena kuti ndi ndalama zimene kugwirizana masiku ano opanda zingwe si kupirira. Choncho, mu zaka zingapo zotsatira, ayenera bwino, amphamvu kwambiri analogue.

"Onse tiyenera kuchita - kukhazikitsa ndi microchip yaing'ono aliyense chipangizo angathe. Cizapereka pamodzi ndi magwiridwe ziwiri zikuluzikulu za mababu: kuwala ndi opanda zingwe ukuthamana "- iye anati.

Iwo ayenera kukumbukira kuti liwiro limene LEDs izi zimaphethira mothamanga kwa diso anthu kuzindikira magetsi. Kotero kuti owerenga maukonde sangathe nkhawa kubuka pa zosasangalatsa.
