Communication device, communication system, program, and data selection method

摘要

The present invention aims to enable appropriate selection of data to be transmitted/received based on the distance between communication devices. A communication device including, a memory unit that stores a plurality of data, a distance information obtaining unit that obtains distance information on a distance from a radio communication device and a data selection unit that selects data from the plurality of data stored in the memory unit based on the distance information obtained by the distance information obtaining unit is provided. The distance information obtaining unit may estimate and obtain the distance information based on a field intensity of a radio signal determined to satisfy a predetermined condition about a noise component among radio signals received from the other radio communication device.
