Hi,
I would like to know how do cellphone differentiate the sent signal from the received signal. Does he use a different antenna for transmission than the antenna which he uses for reception ?
If it's like that, i would like to know if there are some phones which use the same antenna for transmission as the one they use for reception of the signal? If yes, in that case, how do they separate the transmission from the reception part?
Do they use some kind of a switch or chip for that?
Thank you
