Patent ID: 8803664

Claim:
A radio wave control apparatus comprising: a detecting unit that detects an object, other than a communication target device, in a radiation range to which a radio wave radiating unit radiates predetermined radio waves in each of a plurality of radiation directions; a radio wave output judging unit that reduces a radio wave output in one radiation direction of the radiation directions from a maximum value on a predetermined-value basis, and judges whether a radiation range covering the radiation direction using the reduced radio wave output does not cover the entire communication range in which the communication target device is communicable using the predetermined radio waves, or whether no-communication area is caused in the communication range; a radio wave output determining unit that, when the radio wave output judging unit judges that the radiation range does not cover the entire communication range, or that the no-communication area that is caused when the predetermined radio waves reflected on the object is caused in the communication range, determines the radio wave output before the reduction as the radio wave output in the radiation direction and determines the radio wave output in each of the radiation directions; and a radiation range determining unit that determines radiation direction in which the radio wave radiating unit radiates radio waves among a plurality of radiation directions such that the predetermined radio waves are radiated over entire communication range in which the communication target device is communicable using the predetermined radio waves, and no no-communication area that is caused when the predetermined radio waves reflected on the object is caused in the communication range.
