Abstract

Procédé basé sur une plate-forme cellulaire hexagonale dans laquelle des groupes de fréquence au nombre de six ou d'un multiple de six sont orientés et réutilisés dans une même direction. Des antennes directives sont placées au centre de chaque cellule. Chaque antenne rayonne dans un secteur couvrant 60° de la cellule. Les groupes de fréquences réutilisés sont alignés sur des axes orientés à 0°, 120° et 240° de chaque cellule. Chaque axe est formé de trois couches, les deux couches externes possédant une série de fréquences de réutilisation identique. Les groupes de fréquences sont réutilisés dans une même direction le long de chaque axe, ce qui permet de réduire à une le nombre de cellules à interférences dominantes.
