Which sampling rate is commonly used for a wideband wireless telephone?

The commonly used sampling rate for a wideband wireless telephone is 16 kHz. This rate allows for ample audio fidelity while remaining efficient for mobile communication. In the context of telephony, a higher sampling rate ensures a broader frequency range, which translates to clearer audio and improved voice quality, crucial for effective communication.

While 8 kHz is often utilized for traditional telephone lines (narrowband), 16 kHz improves sound quality significantly, making it suitable for digital voice applications where clarity is essential. Higher sampling rates like 22 kHz and 44.1 kHz are typically used for high-fidelity music recording and playback rather than standard telephone communication, as they offer greater fidelity than necessary for voice calls. Thus, 16 kHz serves as an optimal compromise between audio clarity and system performance in wideband wireless telephony.
