Hello,
Are users moving around whilst on the meetings, or are they going to be sitting at a desk and not moving?
There are a few things you can change/edit to enhance the performance of roaming, for example, enabling client match, and disabling lower data rates.
If you are planning on not moving around, there should be much reason for clients dropping off so I would recommend, disabling lower data rates, and drop broadcast multicast.
Hope this helps, Please note that these are my opinions, others may have different suggestions,
Thanks,
Ben
