LED lights could sup­ple­ment WiFi: Study

The Hitavada - - WORLD -

EN­ERGY-sav­ing Light Emit­ting Diodes (LEDs) could re­place WiFi tech­nol­ogy for trans­mit­ting dig­i­tal data, with­out com­pro­mis­ing the qual­ity of light or en­vi­ron­men­tal ben­e­fits, a study has shown.

Re­searchers from the Univer­sity of Ed­in­burgh in the UK found that trans­mit­ting dig­i­tal data via LEDs at the same time as us­ing them to gen­er­ate light does not make the light dim­mer or change its colour. It also does not make LEDs more en­ergy- hun­gry.

Th­ese con­cerns have held back the more wide­spread adop­tion of Light Fi­delity, or LiFi, which uses house­hold LEDs to en­able data trans­fer, said Wa­siu Popoola of the Univer­sity of Ed­in­burgh, who led the re­search.

How­ever, the find­ings help elim­i­nate key hur­dles to us­ing LEDs to help sat­isfy the in­creas­ing global thirst for wire­less com­mu­ni­ca­tions.
