The Multi-Link Aircraft Cellular System makes use of multiple physically separated antennas mounted on the aircraft, as well as the use of additional optional signal isolation and optimization techniques to improve the call handling capacity of the Air-To-Ground cellular communications network These additional techniques can include polarization domain and ground antenna pattern shaping (in azimuth, in elevation, or in both planes) Further, if code domain separation is added, dramatic increases in capacity are realized Thus, the Air-To-Ground cellular communications network can increase its capacity on a per aircraft basis by sharing its traffic load among more than one cell or sector and by making use of multiple physically separated antennas mounted on the aircraft, as well as the use of additional optional signal isolation and optimization techniques

L'invention porte sur un système cellulaire à liaisons multiples avec des avions utilisant de multiple antennes physiquement séparées montées sur l'avion, et sur des techniques optionnelles supplémentaire d'isolement et d'optimisation des signaux améliorant la capacité de traitement des appels air-sol du réseau de communication cellulaire. Ces techniques supplémentaires peuvent inclure un domaine de polarisation et l'élaboration d'un réseau d'antennes au sol (en azimut, en élévation, ou dans les deux plans). Si on ajoute de plus une séparation des domaines de codes, on obtient une augmentation extraordinaire de capacité. Ainsi, le réseau de communication cellulaire air-sol peut-il augmenter sa capacité sur un base par avion en partageant sa charge de trafic entre plus d'une cellule ou d'un secteur, en utilisant des antennes physiquement séparées montées sur l'avion, et en utilisant des techniques facultatives supplémentaires d'isolement et d'optimisation des signaux.
