Transmitting station and receiving station

A transmitting station that transmits wireless signals, the station comprising:

• a first wireless signal processing circuit configured to transmit a wireless signal using a first channel;
• a second wireless signal processing circuit configured to transmit a wireless signal using a second channel different from the first channel;
• a processor;
• and
• a storage medium having computer program instructions stored therein that, when executed by the processor, perform to:
• manage a link state between the first wireless signal processing circuit and a receiving station that receives wireless signals, and a link state between the second wireless signal processing circuit and the receiving station,
• generate, when first data input is of a specific type, second data that is a duplicate of the first data;
• attach, first identification information indicating that the first data is original data, to the first data and attach, second identification information indicating that the second data is replicated data, to the second data;
• and
• output the first data with the first identification information attached to the first wireless signal processing circuit and output the second data with the second identification information attached to the second wireless signal processing circuit.
