    摘要： An ATM-based radiocommunication system adapted for multimedia communication comprises a repeater (1) for providing communication services over a predetermined service area, first radio terminals (31, 32, 33) for communicating with the repeater (1) by using ATM cells, and a second terminal (34) for communicating with the repeater (1) by using ATM cells and communicating with a backbone network (5). The repeater (1) comprises spot beam transmission and reception antennas (11, 12, 13; 15, 16, 17) for providing radio channels within a predetermined service area by means of spot beams, a wide-area beam transmission and reception antenna (14; 18) for providing a radio channel within the predetermined service area by means of a wide-area beam, first transmitters/receivers (21, 22, 23; 25, 26, 27) connected to the spot beam transmission and reception antennas for transmitting and receiving ATM cells, a second transmitter/receiver (24; 28) connected to the wide-area beam transmission and reception antenna for transmitting and receiving ATM cells, and an ATM switching device (29) having input terminals connected to receive ATM cells from the first and second receivers and output terminals connected to the first and second transmitters for directing incoming ATM cells to their respective proper output terminals.
