Le c\u00e9l\u00e8bre institut de normalisation vient de compl\u00e9ter et publier un nouveau standard de r\u00e9seaux sans fil. Il coexistera avec les pr\u00e9c\u00e9dents (802.11x) sans interf\u00e9rences entre r\u00e9seaux <\/p>\n
Le nouveau r\u00e9seau ‘wireless’ transmet, sans fil:
\n-des donn\u00e9es (dont son, images) \u00e0 55Mbps
\n-sur une distance de 100 m\u00e8tres (environ)
\n-sur la fr\u00e9quence de 2,4Ghz<\/p>\n
Son agr\u00e9ment par l’IEEE (Institute of Electrical and Electronics Engineers) porte la r\u00e9f\u00e9rence IEEE 802.15.3 <\/p>\n
Le point fort de ce standard provient de ce qu’il garantit que rien ne viendra interf\u00e9rer avec le flux des donn\u00e9es. Une sp\u00e9cificit\u00e9 qui l’autorise \u00e0 coexister avec les autres technologies \u00ab\u00a0wireless\u00a0\u00bb, comme Wi-Fi (802.11x) ou Bluetooth.<\/p>\n
Mais surtout, il est particuli\u00e8rement bien adapt\u00e9 \u00e0 la transmission, \u00e0 tr\u00e8s haut d\u00e9bit, des donn\u00e9es audio\/vid\u00e9o. <\/p>\n
Il constitue un compl\u00e9ment attendu \u00e0 Wi-Fi, sans doute. Mais encore faut-il que l’industrie l’adopte.<\/p>\n
Les premi\u00e8res applications de cette nouvelle norme 802.15.3 ne sont pas attendues avant la fin 2004. En parall\u00e8le, devront sortir des dispositifs ou accessoires de communication entre PC et appareils \u00e9lectroniques grand public. <\/p>\n
