Abstract :
The frame structure of the future broad-band wireless multimedia communication system using millimeter wave frequencies is investigated. Both portability and small power consumption of the terminal are realized by the gain of base station (BS) antenna. The frame structure in this system is constructed in terms of medium access control (MAC), user data slot allocation, and call control. In addition, tracking of mobile terminals (MTs) and wireless path selection (WPS) are considered for the sake of narrow beam width of the high gain antenna. The performances of WPS taking into account both the MT tracking and the shadowing caused by human bodies are evaluated by computer simulation. Furthermore, the effects of the overlap of covered area by-each BS are evaluated. The throughput performances of two configurations of whose overlap differs are compared. The results show that the proposed frame structure enables the site diversity configuration to become effective even for MTs
