Cov kws tshawb fawb ntawm University of Edinburgh hauv tebchaws United Kingdom tau tshawb nrhiav txog ib xyoo los txiav txim seb puas yog LI-tus yuav cuam tshuam cov kev siv zog ntawm cov hluav taws xob. Txoj kev tshawb no tau nyiaj txiag los ntawm British Engineering thiab Natural Science Research Council (EPSRC).
Cov kws tshawb fawb tau piav qhia qhov project hauv cov ntawv ntawm cov teebmeem ntawm pom lub teeb pom kev ntawm teeb pom kev zoo thiab kev pom zoo. Lawv pom tias LEDs tuaj yeem ua tau raws li cov kev xav tau ntawm kev sib txuas lus sib txuas thiab tsis cuam tshuam rau lub teeb pom kev zoo lossis kev pabcuam lawv li cas.
Kev tshawb nrhiav pom tias LEDs xa tawm cov ntaub ntawv thaum tib lub sij hawm li cov LEDs, uas tsis ua rau lub teeb hloov xim lossis tsaus, lossis kom haus zog ntawm cov LEDs. Kev saib xyuas zoo dua yog qhov tseem ceeb tshaj vim tias nws muaj feem cuam tshuam txog kev noj qab hauv lub cev thiab lub hlwb ntawm cov neeg hauv tsev thiab hauv chaw ua haujlwm.
Wasiu Popoola, tus kws tshawb fawb ntawm Lub Tsev Kawm Ntawv Li Loj thiab Kev Txhim Kho Kev Ua Haujlwm thiab Digital Communications Institutes nyob hauv University of Edinburgh, tau hais tias cov no yog cov kev txhawj xeeb ntawm kev lag luam, uas tiv thaiv cov neeg siv los ntawm kev sib koom ua LiFi nrog tsev coj thiab ua rau kev siv thoob plaws -fi.
Nrog kev pab los ntawm ob tug sib txawv ntawm cov ntaub ntawv hloov tshuab, cov soj ntsuam ntawm tshawb cov creation ntawm dawb lub teeb dawb thiab dawb coj - thawj yog qhib qhov tseem ceeb tswj, thaum lub sij hawm uas LED hom kev lag luam, zoo li Morse code, sai sai hloov, tib neeg qhov muag tsis yog yooj yim mus ntes; ob, nrawm tshaj tawm, lub sijhawm, hloov qhov kev siv ntawm lub teeb kom ua tiav tib lub hom phiaj.
Ob hom kev kawm tau muaj kev vam meej thiab tsis yig txo qhov ci ntsa iab los yog lub neej expectancy ntawm LED qhov muag teev, tsis ua rau muaj kev pom tshwm hauv qhov muag xim. Ob leeg ntawm cov technologies tsuas muaj me ntsis hloov nyob rau hauv tus nqi ntawm cov tshav kub tsim los ntawm cov LEDs. Cov cim ntawm tshav kub yog ib qho tseem ceeb uas xav tau, vim tias qhov kub hnyiab txhais tau tias LEDs siv ntau lub zog los tsim teeb thiab txo kev siv zog.
Dr Popoola ntxiv tias: "Peb lub ntiaj teb nce kev xav tau ntau dua kev muaj bandwidth tshaj muaj nyob rau hauv feem coob RF feem ntawm spectrum." Peb cov kev tshawb fawb tsim rau cov kev paub txog kev paub tseem ceeb, thiab peb cov qhab nees yeej txhawb kev sib txuas lus ntawm kev sib txuas lus yav tom ntej, uas yuav pab kom paub ntau yam ntawm kev lag luam thiab kev sib raug zoo ntawm lub neej yav tom ntej. Cov tuam txhab lag luam yuav tsum paub txog kev koom tes ntawm kev hloov cov ntaub ntawv xa mus rau lawv cov khoom. Peb cov kev tshawb fawb qhia tias siv LED teeb kom ntxiv WiFi tsis muaj kab li cas.
