FIELD: radio engineering.
SUBSTANCE: transmission device includes data channel transmission module by using one of multilobe antenna directivity diagrams and switched antenna directivity diagram, as well as transmission module of certain signal as pilot channel by using one of sector antenna directivity diagrams, multilobe antenna directivity diagram and switched antenna directivity diagram. Multilobe antenna directivity diagram includes many directed antenna directivity diagrams having fixed orientation directions. Switched antenna directivity diagram changes orientation direction in compliance with position of mobile terminal.
EFFECT: improving quality of signal transmitted via superior-to-subordinate communication channel.
