audio speed in mobile communication

[ElectronicsR]

Hello,

What is the audio speed in mobile communication we got?

 

[AnalogKid]

"Audio speed" is not a standard term. If you mean audio bandwidth, the range of frequencies in audio, then a common bandwidth is 300 Hz to 3 kHz or 4 kHz.

I don't know what you are asking about. Wikipedia has several pages on how phones work. Are you asking about how phones work electrically, or why the audio bandwidth is so narrow, or something else?
