Title: Wireless information communication method

IPC: H04L12/413
Filed: 1991-04-09
Abstract: PURPOSE: To apply an information communicating method for controlling the collision of radio communication in a network. CONSTITUTION: A radio local area network 10 including plural stations 12 (12-I-12-N) for transmitting and receiving a message packet through a distribution system 30 uses continuous time-division frames constituted of three timing period T1, T2, and T3 in a time-division multiple system. When the distribution system transmits a synchronizing packet in the period T1, the station which desires the transmission of information transmits an information packet in the period T2. The distribution system re-transmits the received information packet in the following period T1. The arbitrary station which detects the incoincidence of the information packet transmits a collision report code in the next period T3, and the distribution system transmits a collision recognition code to all the stations 12 in response to this signal. Thus, the information transmission is abandoned.  A frequency division multiple method can be executed.
