Abstract:
A wireless telephone equipment comprising:signal generation means for generating a first information signal of an outgoing call;first transmitting means for modulating a first carrier with the first information signal generated by the signal generation means to produce a first modulated signal, wherein a frequency of the first carrier is in a first frequency band corresponding to a cellular frequency band;second transmitting means for modulating a second carrier with the first information signal generated by the signal generation means to produce a second modulated signal, wherein a frequency of the second carrier is in a second frequency band corresponding to a cordless frequency band that is different from the first frequency band of the first carrier;antenna means for transmitting either the first modulated signal produced in the first transmitting means or the second modulated signal produced in the second transmitting means and receiving a third modulated signal in which a third carrier is modulated with a second information signal of an incoming call, wherein a frequency of the third carrier is in a third frequency band corresponding to a combined cellular/cordless frequency band that is different from both the first frequency band of the first carrier and the second frequency band of the second carrier;a single demodulating circuit for demodulating the third modulated signal received in the antenna means to reproduce the second information signal of the incoming call;outputting means for outputting the second information signal reproduced in the demodulating circuit; andcontrol means for controlling the operation of the first transmitting means, the second transmitting means, and the demodulating circuit.
