Signal Strength or Connection Speed icon [closed]

We have a stand alone application on our site that uses realtime video/audio. We are in the process of adding a connection speed icon but it seems we have some disagreements on the icon that should be used.

This icon will show users how consistent/stable the video/audio connection is. Would this be better shown with bars or a connection speed icon?

My personal view is that this is a connection speed icon, and not signal strength. Signal Strength in my mind is more for mobile.
