His current research interest is the development of visible light communications.Experiment of visible light communications: Since we need neither wireless-workers license nor radio station license , communication experiment can be done freely in the laboratory.Visible Light Communications（Information transmission by LED light）Experiment of visible light communication over long distance: The world record is 42.19km that is attained by co-working company. We am challenging to satellite communications.Thestudentsgraduatedfromourlabare“workinghardandplayinghard”,whichisourmotto.Theyareactiveintheareasofelectronicsandcommunications,workingatradioequipmentmanufacturersandmobileservice,railroad,electricpowercompanies.HandaLabIn the FutureAfter GraduationElectrical& Computer Engineering24
