TECHNIQUE FOR SELECTING THE BEST FREQUENCY FOR TRANSMISSION BASED ON CHANGING ATMOSPHERIC CONDITIONS
A communication system transmits data between communication nodes over a data transmission path. The system collects data from at least two different sources to create a fused data stream that is used as the input to a model for determining a frequency at which to transmit the data by skywave propagation. The data is transmitted between the communication nodes at the frequency determined by the model.
1 . A method comprising:
determining that data transmission is not needed, and:
(i) operating in a broadcast mode and transmitting audio to the public in a digital form;
(ii) collecting data from a digital data stream produced during broadcast mode;
(iii) collecting data from at least one additional data stream that has been transmitted by skywave propagation;
(iv) combining the data from the data streams to form a fused data stream;
(v) inputting the fused data stream to a transmission frequency model to determine an optimum working frequency for transmission of a data signal;
determining that data transmission is needed, and:
(i) operating in a data transmission mode in which an instruction data stream is sent by skywave propagation from a first communication node to a second communication node; and
(ii) transmitting the instruction data stream by skywave propagation at the optimum working frequency determined while operating in broadcast mode.
2 . A method comprising:
collecting data from at least two different data streams that has been transmitted by skywave propagation;
combining the data from the data streams to form a fused data stream;
inputting the fused data stream to a transmission frequency model to determine an optimum working frequency for transmission of a data signal;
sending a first signal to switch frequencies from a first communications node for transmitting data to a second communications node for receiving data over a first communication link;
sending a second signal identical to the first signal from a first communications node for transmitting data to a second communications node for receiving data over a second communication link, wherein the second communication link has a greater latency than the first communication link; and
switching the frequency of a data transmission from the first communications node to the second communications node to the optimum working frequency upon successful receipt of either the first signal or the second signal.
