Do all devices in a Wi-Fi network have to be Wi-Fi CERTIFIED Voice-Personal to offer good voice quality?
The Wi-Fi CERTIFIED Voice-Personal designation will help to assure users that voice-enabled Wi-Fi devices are capable of carrying voice over Wi-Fi calls with good audio quality. Both the client device (handset, laptop or other voice-capable device) and the access point should be Wi-Fi CERTIFIED Voice-Personal to ensure the optimal voice quality when making calls over Wi-Fi networks.
Devices that carry Voice-Personal certification are required to have passed all of the necessary certifications for interoperability, including the baseline Wi-Fi certification for core radio standards (802.11a/b/g/n), WPA2 for security, and WMM for Quality of Service. Voice-Personal certification also requires that access points have WMM-Power Save certification for improved power saving on clients that support it.
Other Wi-Fi devices in the network, even if not used for voice applications, should also be Wi-Fi CERTIFIED for core radio standards (802.11a/b/g/n) and WPA2.
