[Q] data connection and its influence on voice connection

Hello,

Is anybody aware of the fact that radio connection (mobile, wifi, bluetooth, gps etc) can influence voice quality connection? Does anybody knows if evidence exists?

If yes it is a good idea to automatically disconnect all active radio connection during the call eg by mean of a tasker.

I just can't find any evidence it is true (eg. Developer of Sanity has got such a functionality in his software)
