Using interpretation for onsite event

[matugraphy]

I have been using interpretation function for a small multilingual onsite event for around 20 participants. The participants logged into Zoom from their phone and could listen to the interpretation. There was no video in Zoom.

Now I'll have the same need, but for a bigger event up to 100 participants and there will be an online broadcast at the same time as well (outside from Zoom). Will this solution work?

How much bandwidth should be available for this?
