1) Why does bandwidth matter so much at events?

Peak moments (doors open, keynotes, headliners) create short, intense spikes in concurrent use such as; ticket scanning, POS, event apps, social uploads, remote presenters, and live streams all at once. High density design guides from Aruba, Cisco, and Ruckus emphasize planning for peaks, validating real throughput in advance, and keeping utilization well below saturation to protect user experience.
