Abstract

Et kommunikasjonssystem sender og mottar kommunikasjoner innenfor en sektorisert celle mellom i det minste en primærstasjon og i det minste en sekundærstasjon. Kommunikasjonssystemet inkluderer en enhet for å generere og å forme en stråle, en antenne for å sende og motta signaler innenfor strålen, og en enhet for å rette strålen. Den formede strålen er rettet mot et flertall av forhåndsbestemte retninger, enten kontinuerlig eller diskret.
