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).
