Usage Scenario - The experience depends on what the users are doing as individuals and as a group on the same network. For example, reading one slide requires only a single frame to be updated; if the user skims and scrolls over the content of a text document, they need a higher number of frames to be updated per second. The communication back and forth to the server in this scenario will eventually consume more network bandwidth.
Also consider an extreme example: multiple users are watching high-definition videos (like 4K resolution), holding HD conference calls, playing 3D video games, or working on CAD systems. All of these can make even a really high bandwidth network practically unusable.
