Zoo kawg! Siv cov LED ntse qhov muag teev kom nkag mus rau Is Taws Nem lossis ua haujlwm raws li routers

Tam sim no txhua zaus koj mus txog qhov chaw, thawj kab lus tsis yog hais nyob zoo, tab sis ib lo lus nug yooj yim thiab meej: “Puas muaj Wi-Fi, Wi-Fi password yog dab tsi? ”Essence Rau qee cov khoom siv ntse, Wi-Fi tau dhau los ua qhov tseem ceeb hauv peb lub neej. Txawm li cas los xij, qee zaum, Wi-Fi tsis yog txhua qhov chaw. Piv txwv li, nyob rau hauv qab daus los yog chav tsev nyuaj, Wi-Fi teeb liab yuav tsis tau them tag nrho. Ob peb hnub dhau los, R & D pab pawg ntawm Department of Electronics thiab Computer Engineering ntawm University of Virginia tab tom ua cov haujlwm sim uas xa cov teeb liab wireless los ntawm LED qhov muag teev —Lifi. Yog tias qhov kev sim zaum kawg ua tiav, koj tuaj yeem ua tus router los ntawm LED qhov muag teev uas tuaj yeem muab faib rau hauv tsev, kom lub teeb liab wireless hauv tsev tuaj yeem nyob txhua qhov chaw. Maite Brandt Pearce, tus thawj coj ntawm R & D team, hais: “Kev xa cov ntaub ntawv wireless los ntawm LED qhov muag teev tsis siv lub zog ntau dua, thiab cov qij LED tsuas yog nthuav cov pab pawg ntawm kev nthuav dav cov teeb liab wireless los ntawm lawv cov teeb pom kev zoo. Wireless Router. ”Lifi tau txhim kho los ntawm wireless cov ntaub ntawv teeb liab los ntawm LED qhov muag teev, uas tuaj yeem ua rau Wi-Fi nyob txhua qhov chaw. Ntawm chav kawm, thawj qhov chaw yog los xyuas kom meej tias tsis muaj lub qhov rais pob tshab nyob rau hauv tag nrho cov chav, txwv tsis pub Wi-Fi teeb liab yuav raug puas los ntawm lub teeb kis tau tus mob. Yav dhau los, ib lub tuam txhab npe hu ua Vlncomm tau thov rau patents uas cuam tshuam thiab siv LIFI thev naus laus zis los txuas rau Is Taws Nem los ntawm lub teeb nthwv dej ntawm lub rooj teeb. Ntxiv nrog rau kev txhim kho cov teeb liab wireless, LIFI yog qhov zoo dua yog tias nws yooj yim heev los siv. Kev hloov ntawm LED qhov muag teev yog yooj yim heev. Lwm qhov txiaj ntsig tseem ceeb ntawm LIFI yog tias tsis muaj kev txwv rau lub teeb nthwv dej xws li cov chaw tsis txaus ntseeg thiab nrov xws li tsev kho mob. R & D cov neeg ua haujlwm hais tias: “Cov cuab yeej no yuav muaj kev cuam tshuam rau Internet ntawm Yam. Piv txwv li, lub tswb moos tuaj yeem sib txuas lus nrog lub lauj kaub kas fes, ceeb toom tias lub lauj kaub kas fes tuaj yeem pib kas fes. Hauv lwm lo lus, cov cuab yeej nruab nrog LED qhov muag teev tuaj yeem sib txuas lus nrog ib leeg. Tau kawg, koj tsis tas yuav nruab nrog lub teeb liab xaim hluav taws xob ib leeg, vim tias ntev npaum li muaj LIFI, nws txaus. ”
