<p>PURPOSE: To obtain a digital radio communication system reduced in the amount of radio data to be transmitted and improved in communication efficiency. CONSTITUTION: When radio packet data are transmitted from a radio terminal 1a to a radio terminal 1b, a radio adapter 2b connected to the radio terminal 1b specifies the frequency channel of radio packet data received in radio reception acknowledgement control packets. Then a radio adapter 1b connected to the radio terminal 1a performs switching to the specified frequency channel and transmits the radio packet data.</p> |
