You think building a huge wifi network is easy?
Try building a huge wifi network that is going to be used by over 9000 hackers.
Thats what they had to do at defcon this year.
There backbone was a cisco fiber switch and there firewall was a quad core xeon! (thats alot considering mine is abut 400mhz)
Defcon’s 20 megabit internet connection runs over a point-to-point wireless link to another hotel that has a point-of-presence in the basement.
So if this sounds like something you want to see check out the link below!
