L’avenir de l’internet haut d\u00e9bit ? Des scientifiques de Google envoient du haut d\u00e9bit sur le fleuve Congo via des faisceaux lumineux, une perc\u00e9e qui pourrait conduire \u00e0 des r\u00e9seaux plus rapides dans les zones recul\u00e9es. Le projet Taara est initi\u00e9 par X, la branche de recherche secr\u00e8te d’Alphabet.<\/em><\/strong><\/p>\n\n\n\n

Il utilise des communications optiques sans fil pour lier la transmission entre deux villes. Cela implique des terminaux qui dirigent des faisceaux de lumi\u00e8re les uns vers les autres dans l’air. C’est une alternative \u00e0 la pose de c\u00e2bles \u00e0 travers le Congo, le fleuve le plus profond du monde.<\/em><\/strong><\/p>\n\n\n\n

Alphabet, la soci\u00e9t\u00e9 m\u00e8re de Google , a envoy\u00e9 le haut d\u00e9bit \u00e0 travers le fleuve Congo en Afrique via des faisceaux de lumi\u00e8re a\u00e9roport\u00e9s, dans sa derni\u00e8re tentative de fournir un acc\u00e8s Internet haut d\u00e9bit aux communaut\u00e9s mal desservies. <\/p>\n\n\n\n

Dans le cadre d’une initiative appel\u00e9e Project Taara, Alphabet transmet des donn\u00e9es entre les villes de Brazzaville (en R\u00e9publique du Congo) et de Kinshasa (R\u00e9publique d\u00e9mocratique du Congo), de part et d’autre du fleuve Congo.<\/p>\n\n\n\n

Google a d\u00e9clar\u00e9 avoir combl\u00e9 \u00ab\u00a0un \u00e9cart de connectivit\u00e9 particuli\u00e8rement tenace\u00a0\u00bb entre les deux villes, qui ne sont distantes que d’environ 4,8 kilom\u00e8tres\u00a0\u00bb<\/em>.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Cependant, la connectivit\u00e9 est cinq fois plus ch\u00e8re \u00e0 Kinshasa car la connexion en fibre doit parcourir plus de 250 miles pour contourner le fleuve Congo, le fleuve le plus profond et le deuxi\u00e8me plus rapide du monde.<\/p>\n\n\n\n

Project Taara a r\u00e9ussi \u00e0 fournir un total de pr\u00e8s de 700 To de donn\u00e9es \u2013 l’\u00e9quivalent de regarder un match de Coupe du Monde de la FIFA en HD 270 000 fois \u2013 en 20 jours avec une disponibilit\u00e9 de 99,9%, a-t-il d\u00e9clar\u00e9.<\/p>\n\n\n\n

Les habitants de Kinshasa ont connu des vitesses d’environ 20 Gbit\/s, ce qui est \u00ab\u00a0une bien meilleure option\u00a0\u00bb que de passer \u00e0 c\u00f4t\u00e9 des avantages de la connectivit\u00e9, selon les chercheurs.<\/p>\n\n\n\n

Google a d\u00e9clar\u00e9 avoir combl\u00e9 un foss\u00e9 de connectivit\u00e9 entre les deux villes, qui ne sont distantes que d’environ 4,8 kilom\u00e8tres mais sont s\u00e9par\u00e9es par la rivi\u00e8re la plus profonde du monde, ce qui rend la pose de c\u00e2bles sous-marins difficile.<\/p>\n\n\n\n

Project Taara utilise des terminaux qui \u00e9mettent des faisceaux lumineux tr\u00e8s \u00e9troits et invisibles. Ceux-ci sont capt\u00e9s par d’autres terminaux qui se verrouillent \u00ab\u00a0comme une poign\u00e9e de main\u00a0\u00bb<\/p>\n\n\n\n

Le projet Taara est la tentative d’Alphabet de fournir un acc\u00e8s Internet haut d\u00e9bit aux communaut\u00e9s mal desservies.<\/p>\n\n\n\n

Comme la fibre mais sans les c\u00e2bles, Taara utilise la lumi\u00e8re pour transmettre des informations \u00e0 des vitesses tr\u00e8s \u00e9lev\u00e9es dans l’air sous la forme d’un faisceau tr\u00e8s \u00e9troit et invisible.<\/p>\n\n\n\n

Les liaisons de communication optique sans fil de Taara, quant \u00e0 elles, utilisent des faisceaux de lumi\u00e8re tr\u00e8s \u00e9troits et invisibles, \u00e9mis par des terminaux sp\u00e9ciaux dans l’air au-dessus du sol, pour fournir des vitesses similaires \u00e0 celles de la fibre.<\/p>\n\n\n\n

Les terminaux de Taara d\u00e9tectent le faisceau de lumi\u00e8re provenant les uns des autres et se verrouillent \u00abcomme une poign\u00e9e de main\u00bb.<\/p>\n\n\n\n

Le projet Taara est orchestr\u00e9 par X, anciennement Google X \u2013 la branche secr\u00e8te de recherche et d\u00e9veloppement d’Alphabet.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Baris Erkmen, directeur de l’ing\u00e9nierie pour Taara, a d\u00e9crit le projet dans un article de blog .<\/p>\n\n\n\n

\u00catre capable de fournir un Internet haut d\u00e9bit jusqu’\u00e0 20 gigabits par seconde (Gbit\/s) est \u00abune bien meilleure option\u00bb que des millions de personnes qui ne profitent pas des avantages de la connectivit\u00e9, car l’\u00e9conomie de la pose de c\u00e2bles dans le sol \u00abne suffit tout simplement pas. empiler \u00bb, a-t-il soulign\u00e9.<\/p>\n\n\n\n

\u00ab Les liaisons de communication optique sans fil du projet Taara diffusent d\u00e9sormais une connectivit\u00e9 \u00e0 la vitesse de la lumi\u00e8re de Brazzaville \u00e0 Kinshasa \u00e0 travers le fleuve Congo <\/em>\u00bb, a d\u00e9clar\u00e9 Erkmen.<\/p>\n\n\n\n

\u00ab Bien que nous ne nous attendions pas \u00e0 voir une fiabilit\u00e9 parfaite dans toutes sortes de conditions m\u00e9t\u00e9orologiques et de conditions \u00e0 l’avenir, nous sommes convaincus que les liens de Taara continueront \u00e0 offrir des performances similaires et joueront un r\u00f4le cl\u00e9 pour apporter une connectivit\u00e9 plus rapide et plus abordable au 17 millions de personnes vivant dans ces villes.<\/p>\n\n\n\n

Le projet Taara fonctionne de mani\u00e8re similaire \u00e0 la fibre optique traditionnelle, qui utilise la lumi\u00e8re pour transporter des donn\u00e9es \u00e0 travers des c\u00e2bles dans le sol.<\/p>\n\n\n\n

Avec la fibre, les donn\u00e9es qui permettent d’\u00e9tablir une connexion Internet parcourent les c\u00e2bles \u00e0 la vitesse de la lumi\u00e8re.<\/p>\n\n\n\n
