Abstract
A wireless communication device has a power receiving wireless communication unit configured to receive power and perform wireless communication utilizing the power, a storage unit configured to store a portion of the power, and a first wireless communication unit configured to perform wireless communication faster and more efficiently than the power receiving wireless communication unit by utilizing the power stored in the storage unit, when amount of the power stored in the storage unit exceeds a first reference level. The power receiving wireless communication unit includes a power receiver configured to receive power and supply a portion of the power to the storage unit, and a second wireless communication unit configured to perform wireless communication slower and less efficiently than the first wireless communication unit by utilizing the power received by the power receiver.
