    Hi,

    With regards to the subject matter, is there a value available for the same?

    Specifically, targeted SNR for voice and data applications?

    Typically the manufacturer of the voice device/application would specify that..

    Often (typically) the RSSI is specified as a target for voice and data applications, as opposed to SNR. Of course, however, SNR is a very important factor! The Validated Reference Design for Skype for Business suggests a minimum SNR of 25 dB (see page 35). This seems like a good suggestion to me.

     

    Ekahau Pro has a profile for planning Voice + Data networks and has a baseline SNR of 20 dB. But most of the other voice related settings are 25 dB.

     

    The AP is generally not a factor in this calculation, but rather the SNR will be a result of the transmit power from the AP - the received signal strength at the client as well as any other received noise/interference.
