\"Ampoule<\/a>
Ampoule Lifi (Wifi)<\/figcaption><\/figure>\n

Ca se passe \u00e0 Shangai, \u00e0 l’universit\u00e9 de Fudan. Des scientifiques ont mis au point une ampoule de 1 W g\u00e9n\u00e9rant son propre signal Wifi, baptis\u00e9 Lifi.<\/p>\n

Les taux de transfert affich\u00e9s sont meilleurs que pour les connexions dites moyennes en Chine, par exemple, il est annonc\u00e9 un d\u00e9bit de 150 Mbps soit 20x plus rapide…<\/p>\n

Le Professeur Chi Nan confie que le signal actuel est couteux et inop\u00e9rant (ou en tout cas, insuffisant).<\/p>\n

“As for cell phones, millions of base stations have been established around the world to strengthen the signal but most of the energy is consumed on their cooling systems,” Nan told\u00a0Xinhuanet<\/a>. “The energy utilization rate is only 5 percent.”<\/p><\/blockquote>\n

Ca fonctionne \u00e9galement avec des Leds et ca permet lorsque vous \u00e9teignez la lumi\u00e8re de couper le signal Wifi, enfin Lifi pour le coup…<\/p>\n

Ils ont “r\u00e9ussi” a connecter 4 ordinateurs simultan\u00e9ment et \u00e0 les connecter \u00e0 l’Internet. J’ai envie de dire “Good Job”, “Keep on that way” \ud83d\ude00<\/p>\n
