Ubuchwepheshe be-VLC, okungukuthi ukuxhumana kokukhanya okubonakalayo (VLC), iqukethe ukudluliswa kwedatha kusetshenziswa ukukhanya. Ama-LED asetshenziswa njengama-transmitter, kuyilapho ama-photodetectors aguqula amasignali okukhanya abe ama-impulses kagesi asebenza njengabamukeli.
Ukusebenzisa ubuchwepheshe be-VLC endaweni yezimboni, lena inselele entsha. Izitshalo zokukhiqiza zinemithombo yokuphazamiseka, njengezindonga, izinto zensimbi nemishini, okungathinta ukusebenza kwazo. Abacwaningi abavela ku-Fraunhofer IOSB-INA kanye ne-Ostwestfalen-Lippe University of Applied Sciences e-Lemgo, eJalimane benze umkhankaso wokulinganisa ngokuhlola izici ezintathu ezinethonya: ukukhanya okuzungezile, izinhlayiya zothuli e imibono evela kubantu abahamba kancane nezimoto.
Ukulinganisa izenzakalo ezenzeka ngokushesha kune-millisecond, kukhona ubuchwepheshe obuthuthukisiwe. Abacwaningi abavela ku-National Institute of Optics (INO) ye-CNR yaseFlorence kanye neNyuvesi yaseFlorence banelungelo lobunikazi bedivayisi esekelwe kubuchwepheshe bokuxhumana obusha be-VLC (Visible Light Communication) ukuvumela izimoto nezimpawu zomgwaqo ukuthi zixhumane nge-millisecond eyodwa futhi gwema ukungqubuzana.
Ubuchwepheshe be-VLC busekelwe embonweni wokulungisa ukuqina kokukhanya kwe-LED ukuze kudluliselwe ulwazi lwedijithali: usebenzisa lolu hlelo nokukhanya okungabonakali ngeso lomuntu, idivayisi enelungelo lobunikazi ivumela amarobhothi nezimoto ukuthi zishintshisane ngolwazi olungenantambo ngaphansi kwe i-millisecond futhi ugweme imithelela nokuqondisa okuyingozi. Minyaka yonke, empeleni, cishe abantu abayizigidi eziyi-1.3 bafa ezingozini zomgwaqo emhlabeni, abantu abangama-3287 ngosuku. Ukwakha izinto ezikwazi ukuvimbela ukushayisana kungenza imigwaqo iphephe futhi ukuphila kwabashayeli bakhululeke kakhudlwana.
Idivayisi, okwamanje esebenza emkhakheni wezimoto, ukukhanya komphakathi nezimpawu zomgwaqo, ingase isetshenziswe esikhathini esizayo emikhakheni eminingi yezimboni neyomphakathi, njengokuvikela, ukunakekelwa kwezempilo).
Ubuchwepheshe bethulwe kudemo yokusebenza, ehlanganisa ubuchwepheshe obubuzwayo nobuchwepheshe be-5G, ngempumelelo enkulu. Kukhona ukusebenzisana nezinkampani ezinentshisekelo yokusebenzisa i-IP exhunywe kulolu hlelo lokusebenza lwelungelo lobunikazi. Isicelo selungelo lobunikazi sisanda kufakwa kunguqulo yobuchwepheshe be-VLC ukuze kusetshenziswe imnyuziyamu kanye/noma ezindaweni zentengiso. Ngale ndlela kungenzeka ukuhlinzeka ngezinsizakalo ezintsha ezinikezelwe kubasebenzisi, kuyilapho uvumela indawo yabo ngisho nasezindaweni zasendlini lapho ubuchwepheshe be-GPS bungasebenzi.
