Le consortium Europe-Cor\u00e9e \u20185G Champion\u2019, coordonn\u00e9 par le CEA-Leti proposent aux JO de Pyongcheng la toute premi\u00e8re preuve de concept de r\u00e9seau 5G au monde, enti\u00e8rement int\u00e9gr\u00e9 et op\u00e9rationnel. Cette preuve de concept 5G sera mise \u00e0 la disponibilit\u00e9 des visiteurs, au K-ITC center et dans la Yulgok Street, aussi intitul\u00e9e \u00ab IoT street \u00bb, proche du village olympique de Gangneung. Des stations de type \u00ab backhaul \u00bb, d\u00e9velopp\u00e9es par la partie europ\u00e9enne et cor\u00e9enne du consortium, seront install\u00e9es au K-ITC center et le long de cette \u00ab IoT street \u00bb.<\/p>\n

Le d\u00e9bit d\u00e9pend de plusieurs facteurs, notamment le type d’application et de service utilis\u00e9s, la bande de fr\u00e9quence disponible et la distance de communication.  Si, aujourd\u2019hui, les r\u00e9seaux de type 3 et 4G, permettent d\u00e9j\u00e0 d\u2019atteindre localement (en fibre optique notamment) un type de d\u00e9bit de l\u2019ordre de 100 Mbits\/s pour l\u2019utilisateur final, les bandes utilis\u00e9es sont satur\u00e9es, de sorte que l\u2019utilisateur n\u2019a acc\u00e8s qu\u2019\u00e0 des fractions du d\u00e9bit maximal.
\nLa 5G, gr\u00e2ce \u00e0 l\u2019utilisation de nouvelles bandes de fr\u00e9quence et le d\u00e9veloppement de nouvelles architecture basse consommation et faible co\u00fbt, a pour objectif de d\u00e9mocratiser ce type de lien via des stations dites \u00ab backhaul \u00bb (antenne point-\u00e0-point, d\u00e9velopp\u00e9s notamment au CEA Leti) et d\u2019atteindre des d\u00e9bits de l\u2019ordre du Gbits\/s. Les stations \u00ab backhaul \u00bb, d\u00e9velopp\u00e9es dans le projet 5G Champion sur la bande de 28 GHz, permettent d\u2019atteindre des d\u00e9bits de l\u2019ordre de 2.5 Gbits\/s. Ce d\u00e9bit est possible gr\u00e2ce \u00e0 l\u2019utilisation d\u2019une toute nouvelle bande de fr\u00e9quence.
\nDes formes d\u2019onde pour la communication par satellite et des algorithmes ont \u00e9galement \u00e9t\u00e9 \u00e9tudi\u00e9es pour suivre des objets connect\u00e9s en mouvement et ce, jusqu\u2019\u00e0 500 km\/heure. Un savoir-faire tr\u00e8s attendu pour \u00e9quiper les trains \u00e0 grande vitesse avec la 5G.<\/p>\n

\u00ab Les syst\u00e8mes de communication 5G derni\u00e8re g\u00e9n\u00e9ration vont changer la donne mondiale en termes de perspectives technologiques, \u00e9conomiques, soci\u00e9tales et environnementales, explique Emilio Calvanese Strinati, directeur recherche et innovation au CEA-Leti. Le haut d\u00e9bit rend les technologies plus accessibles encore. Les Jeux olympiques d\u2019hiver 2018 \u00e0 PyeongChang, en Cor\u00e9e du Sud, sont l\u2019occasion d\u2019en faire la d\u00e9monstration, deux ans avant le lancement officiel de la 5G pour le grand public, en 2020. \u00bb<\/em><\/p>\n

Ces technologies sont particuli\u00e8rement int\u00e9ressantes pour les communications mobiles large bande et grande vitesse et pour l\u2019internet des objets.<\/p>\n
