Description

aftastningsmodtagerens (240) modtagere kan forbindes til en eller flere af seks vektorantenner (214). Ved udøvelse af fremgangsmåder ifølge den foreliggende opfindelse vedligeholder den mikroprocessorstyrede (358) basispladskontrol kommunikationsveje til mobile og transportable radiotelefoner af høj kvalitet ved periodisk at aftaste deres signalstyrke og, når signalstyrkeforringelse detekteres, enten ændre den sektorantenne (214), der er forbundet til talesende-modtagerne (220,230), øge eller mindske radiotelefonens udgangseffekt, eller overdrage radiotelefonen til en anden celle.
