The antenna 101 and the cellular transceiver 111 are used for transmitting and receiving cellular radio signals. The cellular transceiver 111 converts a baseband signal output from the processor 160 into the cellular radio signal, and transmits the same from the antenna 101. Further, the cellular transceiver 111 converts the cellular radio signal received by the antenna 101 into the baseband signal, and outputs the same to the processor 160.
The antenna 102 and the WLAN transceiver 112 are used to transmit and receive a WLAN radio signal. The WLAN transceiver 112 converts a baseband signal output from the processor 160 into a WLAN radio signal, and transmits the same from the antenna 102. Further, the WLAN transceiver 112 converts a WLAN radio signal received by the antenna 102 into a baseband signal, and outputs the same to the processor 160.
