Estimating the term…
In a communication terminal that is capable of carrying out communications based on a plurality of communication standards, for example, a cellular phone, information representing a reception carrier frequency of a wireless channel being received by a cellular-phone functional block is output from a CPU to a contactless-IC-card-reader/writer functional block. In the contactless-IC-card-reader/writer functional block, a controller controls a switching circuit to switch a transmission carrier frequency being used so that harmonic components of an electromagnetic wave radiated from a coil antenna will not work as an electromagnetic-interference wave that affects reception sensitivity of the cellular-phone functional block.
A wireless communication circuit comprising:
A wireless communication terminal comprising:
A wireless communication method comprising:
A recording medium having recorded thereon a computer-readable program that allows a computer to execute processing for receiving a first electromagnetic wave having a first carrier frequency for communication based on a first wireless communication standard, and processing for transmitting a second electromagnetic wave having a second carrier frequency for communication based on a second wireless communication standard, the program comprising a controlling step of controlling the second carrier frequency so that a frequency of an electromagnetic-interference wave that is generated by transmission of the second electromagnetic wave does not fall within a predetermined frequency range with which reception sensitivity to the first electromagnetic wave is degraded.
