G.711 (Cellular Networking)

The ITU-T standard for PCM encoding telephone audio on an 64 kbps channel. Because it operates at an8 kHz sampling rate (8 bits per sample) it can only encode frequencies between 0 and 4 kHz. There are two encoding variants. mu-law and A-law. A-law is used for international circuits and represents smaller signals with greater fidelity.


G.711 (Networking)

G.711 is a Pulse Code Modulation (PCM) waveform codec. G.711 provides very good sound quality but requires 64kbps of bandwidth. G.711u is used mainly in North America and G.711a is used in most of the rest of the world. See also Codec.
