Can I limit the bandwidth of meeting participants in Zoom?

It is not possible to limit the bandwidth of participants.

Bandwidth cannot be limited, but here are some related settings as a tip for a more comfortable meeting.

Turn OFF group HD video

When the group HD video setting is ON, the video quality will be 720p and consume bandwidth.

• If you want to turn off group HD video throughout the organization, it is recommended that the
  account owner or administrator turn off [Group HD video] in Zoom Sign-in> Account settings> Meeting.
• If you want to turn off group HD video for each individual,
  you can sign in to your own account, go to My Meetings settings, and turn off group HD video.
• In the case of the photo above, the administrator has locked the group HD video so that it can not be turned ON for the entire organization.
