A is a point-to-point radio link used to transmit information (voice, data, or video) via highly directional electromagnetic waves between two fixed locations. Operating primarily in the frequency range of 1 GHz to 40 GHz (and up to 86 GHz in modern systems), these links are essential for backhauling mobile networks (like 4G/5G), connecting remote industrial sites, and TV broadcasting. 1.

: Utilisation de fréquences porteuses (généralement entre 1 GHz et 40 GHz ) pour l'interconnexion de sites distants. : Pas de support physique requis, idéal pour les zones difficiles d'accès ou déploiements rapides. Inconvénients : Sensibilité aux conditions atmosphériques et nécessité d'une visibilité directe. 2.
