<p>More than one communication device that is to simultaneously transmit identical data through multiple data transmissions using different radio wave multiplex types is determined based on the link qualities of a plurality of communication devices. Then the multiple data transmissions are made by transmitting the identical data with synchronized timings at the determined communication apparatuses. The link qualities are determined by measuring received signal intensities, bit error rates, or frame error rates at the respective communication devices at the time of the multiple data transmissions using two radio wave multiplex types orthogonal to each other.</p> |
