PROBLEM TO BE SOLVED: To set appropriate transmission power through learning when two wireless communication apparatuses have a particular positional relation and distance relation.SOLUTION: A wireless communication apparatus of the present invention records communication history including positional information on a transmission side and a reception side, a transmission power value, and information on reception intensity at the reception side; performs communication place registration if a combination of places of a particular transmission side and reception side included in the communication history reaches a prescribed number, and calculates and sets a next time transmission power value per registered communication place; confirms whether a communication place is a registered communication place at the time of transmission; and sets a transmission power value to the next time transmission power value set correspondingly to the communication place and performs transmission if the communication place is a registered place.SELECTED DRAWING: Figure 1 |
