Two frequencies are used, one for upstream and one for downstream. The modulation scheme itself just uses amplitude and phase

A full-duplex QAM-16 modem uses two frequencies.

• A full-duplex QAM-16 modem uses two frequencies, one for upstream and the other for downstream.
• Modem uses channels to communicate with the internet service provider.
• These two channels are responsible for the bandwidth and speed of the internet.
• when data is sent to another ISP then it is called downstream on the other hand if data is received from another ISP then it is called upstream.
