PROBLEM TO BE SOLVED: To provide a network communication system which has a high transmission speed and a large amount of a transmission capacity, and communication equipment. SOLUTION: In this network communication system, a radio center device 10 is made to receive signals that are sequentially relayed and transmitted to a plurality of radio terminal devices 20. In a radio terminal device 20, a sensor 24 collects physical data, and a radio transmitting and receiving part 21 transmits and receives the radio signals, and a signal processing part 23 processes the signals from the sensor part 24 and the signals received by the radio transmitting and receiving part 21. The radio center device 10 receives the radio signals from the radio terminal devices. Thus, higher transmission speed and a larger transmission capacity than those of a conventional art can be obtained. COPYRIGHT: (C)2006,JPO&NCIPI
