I have an one day event in July 2012, hosting 250 attendees for a social media event. We will be uploading live video to a website, allowing the press to access the web, and some vendors will be showing off their web sites for clients and visitors. The staff will need access for uploading files and information as needed. We had the event last year and tried a cable modem brought in with 2x2 megs just for the streaming video which worked well. I had 4 wireless hot spots, rented from a company 1.5 mbps x 780 kbps, which was were a complete failure. I was assured the 4 hot spots would be enough, but they did not work.

What would be the proper way to get the bandwidth required to make the one day event successful? The setting is a Private Country Club where running cables everywhere is very tough.
