<p>PROBLEM TO BE SOLVED: To provide a flexible computer radio network. SOLUTION: The radio network of a computer or another portable electronic device is made to enable transmitting data from a master computer 14 to one or more client computers 18. The master computer 14 broadcasts data as against the client computer 18 and a transponder 20. When data is received, the transponder 20 transmits recognition for reporting that data is received to the master computer 14. When the master computer 14 receives recognition, it is assumed that the whole client computers 18 receive data so that data transmission is continued. In the meantime, unless the master computer receives recognition within a scheduled time (a time-up period) from data transmission, it is assumed that data is not received by the whole computers so that data is transmitted again. The client computer 18 completes a data processing when both data and recognition are received.</p> |
