    Does the communication controller inside such dual-mode mobile have two PHYs - one for GSM and second for UMTS?

    Or can one PHY support both technologies?

    Thanks.

    Hi,

    I meant the Physical Layer Protocol - the first and lowest layer in the seven-layer model.

    This layer is responsible for the transmission and reception of data (for example, modulation, demodulation).
