MICROWAVE & RF RF - Hyper et Fibre dans la fracture numérique : une chance pour la filière des « hypers » 1

Les attentes et les logiques La 4 G: pas de capacité sans déploiement de petites cellules et 80% du backhaul se fera en sans-fil (enquête SARABAND auprès de 20 opérateurs hors France) L’accès en périurbain, résidentiel et rural on attend toujours les promesses de la fibre mais: – On ne saurait utiliser 100Mbps dans un foyer, et une PME high- tech de 30 personnes consomment 30Mbps “peak”, – La fibre est très chère et contraignante en capillaire, ni les opérateurs ni les collectivités n’ont les moyens à court ou moyen terme – La radio et les hyperféquences font des progrès rapides et constants ouvrant de plus en plus de spectre donc de capacité utilisable sans travaux (Fréquences, GaN, modems, antennes) 2
