New Li-Fi Inthanethi ngokushesha izikhathi angaphezu kwangu-100-Wi-Fi

Umsunguli wendlela isibani neze ngicabange ukuthi ngolunye usuku emsebenzini wakhe ngeke isetshenziselwe kuphela ukukhanyisa amakhaya emhlabeni wonke, kodwa futhi ngoba ukudluliswa kwedatha ezinobukhulu obuhlukahlukene. Isibonelo, izolanda ulwazi kusuka kumasathalayithi emkhathini usebenzisa kumadivayisi amancane ngesandla. Nokho, lapho umuntu eba Li-Fi ekhaya ukukhanyisa angase ngokushesha kabili njengoba ifomu idatha, ngoba lobu buchwepheshe ishesha izikhathi angaphezu kwangu-100-Wi-Fi.

"Umzali" imishini yezokuxhumana engenazo izintambo: ungubani?

Umqondo womuntu oyedwa ukuxhumana okungenawaya Inthanethi walethwa ukuphila Garoldom Haasom, ukusebenza eyunivesithi Edinburgh. Lokhu kwenzeka ngo-2011.

Ososayensi esetshenziswa ebonakalayo zokuxhumana ukukhanya (VLC), ukuthumela idatha ngesivinini kakhulu. Eqinisweni, kwakungisiza kube inkomba ukukhanya ngendlela emangalisayo okusheshayo agqoke ngaphakathi nangaphandle kwe-ukuze bahlabe umkhosi mlayezo binary code (1s futhi 0s). Ekuqhubeni nezinye ucwaningo ngendlela efanayo ukuze uthumele ubuchwepheshe ukuvumele kuphela kuze kube 224 gigabits ngomzuzwana. Ukuze uqhathanise, Wi-Fi iyakwazi ukufinyelela isivinini megabits 600 ngobude ngesikhathi esifanayo.

Ubungcono etholakalayo

Ngenxa yalo msebenzi we nkampani Estonia Velmenni kwenza kwenzeka ukuba transmission technology namandla kakhulu. Ngo amahhovisi kanye izitshalo zezimboni inhlangano e Tallinn sebeqalile kakade ukuhlola uhlobo olusha imishini yezokuxhumana engenazo izintambo, ngokuthi Li-Fi. Kulezi zimo, onjiniyela ochwepheshe kungawufinyelela uxhumano ngesivinini esingaba Gigabit ngomzuzwana.

Ngaphezu Akumangalisi okusheshayo ukudluliswa kwedatha, Li-Fi Ubuye eziningi nezinye izinzuzo phezu esasisandulele. Ngokwesibonelo, ngokungafani-Wi-Fi, ubuchwepheshe obusha lithuthukile ukuphepha. Nge ukusebenzisa kwayo isiginali wadluliselwa-ugongolo optical, okusho ukuthi akunakuba udabula izindonga, kanjalo ezincisha isikhala umsebenzisi kwabantu bangaphandle.

Yiqiniso, lokhu kuzokwenza abanye ngokuphazamiseka. Kuyadingeka ukuba umsebenzisi basishiye, ngeke bakwazi ukuxhuma kunethiwekhi engenantambo. Nokho, uma Isivimbo ngesimo izindonga abayonqotshwa, le Li-Fi kuvula eziningi amathuba. Ngokwesibonelo, kuvumela ukuthumela imilayezo phezu ngobubanzi okuningi imvamisa ububanzi kuka-Wi-Fi, nesebenzela phakathi amaza ka 2.4 GHz no-5 GHz.

amathemba Ikusasa

Onjiniyela bakholelwa ukuthi Li-Fi kungaba esikhundleni Iyafaneleka evamile kithi wireless technology. It kuzokuvumela ukuba sigweme 'isiminyaminya "kunethiwekhi, okuyinto zibangelwa yokuthi Inthanethi kabanzi zasakazekela kulo lonke izwe.

Ngokusho izibalo wokulungiselela, senyanga ukusetshenziswa kwedatha global kumele singeqi 24.3 exabytes kakade nge-2019. Nakuba singakwazi kuphela bathi lemali ekufanele ukuxhumana okungenawaya yesimanje akakwazi ukubhekana nesimo. Ngakho-ke, eminyakeni embalwa ezayo, badinga i ethuthukisiwe, Analogue namandla kakhulu.

Engxoxweni aba nayo yamuva nge iyashelela uxhumano «TED» Haas waphikelela ngokuthi yasendlini abavamile LED-isibani kungenziwa iguqulwe kalula ibe omoya Li-Fi, ukuhlinzeka abasebenzisi inthanethi.

"Bonke kufanele senzeni - ukufaka microchip encane zonke kudivayisi ezingaba khona. Sizoba ndawonye ukusebenza ezimbili eziyinhloko ama: ukukhanya futhi wireless ukudluliswa kwedatha ", - esho.

Kufanele kuphawulwe ukuthi ijubane ngawo la LED blink okusheshayo kakhulu iso womuntu ukuze abone ukuthi izibani. Ngakho ukuthi abasebenzisi inethiwekhi ayikwazi bakhathazeke nokuqubuka ecasulayo.
