無線通信装置及び無線通信方法

Japanese Patent JP7179720

B2

The wireless communication device relating to one embodiment of the present technology is provided with a communication unit, conversion unit, generation unit, and supply unit. The communication unit is capable of transmitting/receiving electromagnetic waves for narrow band communication. On the basis of a first reference signal, the conversion unit converts the frequency of a reception signal into an intermediate frequency, said reception signal having been generated corresponding to reception of the electromagnetic waves for the narrow band communication. On the basis of a second reference signal having a frequency different from that of the first reference signal, the generation unit generates a transmission signal to be used for transmission of the electromagnetic waves for the narrow band communication. The supply unit is capable of performing switching between operation of supplying the first reference signal to the conversion unit, and operation of supplying the second reference signal to the generation unit.
