A novel wireless multimedia network employing a time division duplex CDMA/TDMA scheme is proposed. The network connects mobile multimedia terminals to an ATM-based LAN through a radio central unit, and provides both uplink and downlink with unbalanced data rates in the same frequency band. The uplink employs a CDMA scheme to transmit low-speed human interface signals, and the downlink employs a TDMA scheme to transmit high-speed video signals. The data rates of both links are independent from that of the LAN.
