A device divides a sampled sound signal into a high frequency signal and a low frequency signal, individually encodes the high frequency signal and the low frequency signal, and generates error detection code pertinent to the high frequency ADPCM data and the low frequency ADPCM data. The device replaces data pertinent to some of a plurality of bits which configure the low frequency ADPCM data with the error detection code and transmits them. A receiver side receives the high frequency ADPCM data and the low frequency ADPCM data, and individually processes the high frequency ADPCM data and the low frequency ADPCM data in accordance with a value of the error detection code.

Wireless communication device and communication terminal

A wireless communication apparatus is provided. The apparatus includes a wireless transceiver which conducts communication with another wireless communication apparatus using a channel belonging to a first band of a plurality of frequency bands, and a switching unit which switches the channel being used by the wireless transceiver to a different channel of a second band of the plurality of frequency bands other than the first band.
