Method for reducing message error rate within real-time exchange radio-frequency communications systems

A method for transmitting data within a real-time data exchange radio-frequency communications network, comprising:

• sending a message to be transmitted from a main processor to a radio-frequency modem;
• calculating the time at which to key a radio for transmitting the message, the time at which to transmit the message, and the time at which to unkey the radio;
• verifying whether the radio-frequency modem is receiving a message;
• recalculating the radio keying time, the message transmitting time and the radio unkeying time if the radio-frequency modem is receiving a message and repeating said verifying step until the radio-frequency modem is not receiving a message;
• upon the radio-frequency modem not receiving the message, keying the radio at the calculated radio keying time;
• inserting the number of packets to be transmitted onto the control data of a frame header and then transmitting the frame header at the calculated message transmitting time;
• transmitting each packet until all packets have been transmitted;
• and unkeying the radio at the radio unkeying time.
