WiFi tam sim no yog qhov tseem ceeb ntawm peb lub neej xws li nyeem ntawv, ua si, ua haujlwm thiab lwm yam.
Cov khawv koob ntawm xov tooj cua tsis muaj cov ntaub ntawv rov qab los ntawm cov khoom siv thiab wireless routers.
Txawm li cas los xij, lub teeb liab ntawm wireless network tsis yog ubiquitous.Qee lub sij hawm, cov neeg siv nyob rau hauv ib puag ncig nyuaj, tsev loj lossis villas feem ntau yuav tsum tau siv cov wireless txuas ntxiv los ua kom cov kev pab cuam ntawm wireless signals.
Txawm li cas los xij, lub teeb hluav taws xob muaj nyob hauv ib puag ncig sab hauv tsev.Nws puas yuav zoo dua yog tias peb tuaj yeem xa cov teeb liab wireless los ntawm lub teeb ntawm lub teeb hluav taws xob?
Maite Brandt Pearce, tus xibfwb ntawm Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob thiab Computer Engineering ntawm University of Virginia, tab tom sim siv cov coj los xa cov teeb liab wireless sai dua li kev sib txuas hauv Is Taws Nem tam sim no.
Cov kws tshawb fawb tau hu ua qhov project "LiFi", uas siv tsis muaj zog ntxiv los xa cov ntaub ntawv wireless los ntawm LED qhov muag teev.Tam sim no ntau lub teeb tau hloov mus rau LEDS, uas tuaj yeem muab tso rau hauv ntau qhov chaw hauv tsev thiab txuas nrog wirelessly hauv Is Taws Nem.
Tab sis tus xibfwb Maite Brandt Pearce cov lus qhia tsis txhob cuam tshuam koj lub wireless router sab hauv.
LED qhov muag teev emit wireless network signals, uas tsis tuaj yeem hloov WiFi, tab sis tsuas yog ib qho kev pab txhais tau tias nthuav dav wireless network.
Ua li no, txhua qhov chaw hauv ib puag ncig uas koj tuaj yeem nruab lub teeb pom kev tuaj yeem yog qhov chaw nkag mus rau WiFi, thiab LiFi muaj kev nyab xeeb heev.
Twb tau, tuam txhab lag luam tab tom sim siv LI-Fi los txuas rau Is Taws Nem siv lub teeb nthwv dej ntawm lub rooj teeb.
Xa cov teeb liab wireless los ntawm LED qhov muag teev tsuas yog ib qho thev naus laus zis uas muaj kev cuam tshuam loj hauv Is Taws Nem ntawm Yam.
Los ntawm kev txuas mus rau lub wireless network muab los ntawm lub teeb, lub tsev lub tshuab kas fes, tub yees, lub rhaub dej thiab lwm yam tuaj yeem txuas nrog Is Taws Nem.
Nyob rau hauv lub neej yav tom ntej, peb yuav tsis tas yuav txuas ntxiv lub wireless network muab los ntawm wireless router rau txhua chav hauv tsev thiab txuas cov khoom siv rau nws.
Ib qho yooj yim LiFi thev naus laus zis yuav ua rau peb siv wireless network hauv peb lub tsev.
