Abstract
Une antenne distribuée et un système de liaison terrestre fournissent une connectivité de réseau pour un déploiement de petites cellules. Plutôt que de construire de nouvelles structures et d'installer des câbles et des fibres supplémentaires, les modes de réalisation décrits ici portent sur l'utilisation de communications à ondes millimétriques à grande largeur de bande. Un système aérien à ondes millimétriques peut être utilisé pour fournir une connectivité de raccordement. Des modules peuvent être placés sur l'infrastructure existante, telle que des réverbères et des poteaux utilitaires, et les modules peuvent contenir des stations de base et des antennes pour transmettre les ondes millimétriques vers et depuis d'autres modules. Des signaux de liaison montante et de liaison descendante (c'est-à-dire des signaux dirigés vers/depuis une station de base depuis/vers un noeud de communication) peuvent être spectralement divisés en canaux de commande, les segments spectraux de liaison montante et de liaison descendante comprenant chacun : des signaux modulés qui peuvent être convertis en fréquence à leur bande de fréquence originale/native pour permettre aux noeuds de communication de communiquer avec un ou plusieurs dispositifs mobiles ou stationnaires, et des signaux pilotes qui peuvent être fournis avec certains ou tous les segments spectraux pour atténuer la distorsion créée entre les signaux de communication. Les signaux pilotes peuvent être traités par des émetteurs-récepteurs de noeuds de communication vers le haut et vers l'aval afin d'éliminer la distorsion d'un signal de réception (par exemple, une distorsion de phase).
