Intsha ye-Inthanethi ye-Li-Fi iphindwe ngama-100 ngokukhawuleza kune-Wi-Fi

Umvelisi we-bulb ukukhanya engalindelanga ukuba ngolunye usuku indalo yakhe ayisetyenziselwa ukukhanyisa izindlu ezijikeleze ihlabathi, kodwa ukuhambisa idatha yemigangatho eyahlukeneyo. Umzekelo, uya kuvumela ukulayisha ulwazi ukusuka kuma-satellites kwisithuba usebenzisa izixhobo ezincinci ezigcinwe ngesandla. Nangona kunjalo, ngokuqaliswa kwe-Li-Fi, ukukhanya kwekhaya kunokukhawuleza ngokuphindwe kabini njengendlela yokudluliswa kwedatha, kuba le teknoloji iphindwe ka-100 ngokukhawuleza kune-Wi-Fi.

"Umzali" onxibelelwano olungenantambo: ngubani na?

Ingcamango yoxhumano lwe-Intanethi engaxilwanga nge-intanethi yenziwa nguHarold Haas, osebenza kwiYunivesithi yase-Edinburgh. Oku kwenzeka ngo-2011.

Usosayensi wasebenzisa ukukhanya kokubonisana okubonakalayo (VLC) ukuthumela idatha kwizinga eliphezulu kakhulu. Enyanisweni, isebenze njengesibane sesibonakaliso sokukhawuleza ngokukhawuleza, ukuqhaqhafaza nokuvalela ukwenzela ukubuyisela kwakhona umyalezo kwikhowudi yebinary (1 no-0). Kweminye imvavanyo ngokufanayo, iteknoloji yavumela kuphela ukuya kuma-gigabits angu-224 ngesibini. Ukuthelekisa, i-Wi-Fi iyakwazi ukuphuhlisa isivinini malunga nama-megabits angama-600 kwixesha elifanayo lexesha.

Ukuphuculwa kubonakala

Ndiyabulela umsebenzi weenkampani zase-Estonia zaseVelmenni, iteknoloji yokudluliselwa kwedatha enamandla kunokwenzeka. Kwiofisi kunye nokufakelwa kwemveliso yombutho eTallinn, uhlobo olutsha lwezonxibelelwano ezingenazintambo, olubizwa ngokuthi yi-Li-Fi, seluqale luvavanywe. Kule miqathango, iingcali zophuhliso zikwazi ukufezekisa isivinini soxhumano malunga ne-gigabit yesibini.

Ukongezelela kokudluliswa kwedatha ngokukhawuleza, uLi-Fi unamanye amancedo ngaphezu kwexesha elidlulileyo. Umzekelo, ngokungafani ne-Wi-Fi, iteknoloji entsha inyuse ukhuseleko. Xa isetyenziswe, umqondiso usasazwa ngokukhanya okukhanyayo, oku kuthetha ukuba awukwazi ukudlula iindonga, ngaloo ndlela unciphisa isikhala somsebenzisi kwi-intrusions.

Kakade, oku kuya kubangela ukuphazamiseka okuthile. Kufuneka kuphela ukuba umsebenzisi avele egumbini, njengoko engakwazi ukuxhuma kwi-network wireless. Nangona kunjalo, ukuba le ngqongquthela ngendlela yeendonga iyanqotshwa, i-Li-Fi iya kuvula ezininzi iimeko. Umzekelo, kuya kuvumela ukuthumela imilayezo kwibala lohlu olubanzi kakhulu kune-Wi-Fi, esebenza phakathi kwe-2.4 GHz ne-5 GHz.

Iinjongo zekamva

Abaphuhlisi bacinga ukuba i-Li-Fi ingaba yinto efanelekileyo yokutshintshela iteknoloji engaqhelekanga. Kuya kupheka "ukuhamba kweendlela" kwintanethi, ebangelwa kukuba i-Intanethi iyaqhubeka isasazeka kwihlabathi jikelele.

Ngokweziqikelelo zokuqala, ukusetyenziswa kwedatha yenyanga yenyanga kufuneka kudlule ii-exabytes ezingama-24.3 ngo-2019. Ngethuba singathetha nje ukuba lo ngumqulu onxibelelwano lwe-wireless wanamhlanje awukwazi ukuhlangabezana nayo. Ngoko ke, kwiminyaka embalwa ezayo bafuna i-analog ephuculweyo, enamandla kakhulu.

Kwi-interview ye-TED, i-Haas iqinisekise ukuba ii-bulbs zokukhanya zezindlu eziqhelekileyo ziyakwazi ukuguqulwa kwii-Li-Fi, zibonelele i-intanethi kubasebenzisi be-intanethi.

"Yonke into esimele siyenze ukufaka i-microchip encinci kweso sixhobo ngasinye. Oku kuya kusenza sidibanise iimbini ezimbini eziphambili zezibane zokukhanya: ukukhanyisa kunye nokudluliselwa kwedatha, "watsho.

Kuyafaneleka ukuba uqaphele ukuba isantya apho ii-LED zitshisa ngokukhawuleza kweso luntu ukuze zibone izibane. Ngoko abasebenzisi benethiwekhi abanako ukuxhalabisa ngokukhawuleza ukukhanya.
