I'll be interested to see how it's implemented. I work for a large university in network engineering and wifi coverage for a large outdoor area is a real challenge. If you're just doing hotspotting it's not as bad, but making sure you have enough IP addresses available, access point capacity, device roaming, spectrum allocation - it's a serious challenge. Enterprise-class wireless access points are typically good for 40-50 "active" clients per wifi radio - imagine the hub during fireworks, where would the access points hang? We're looking into doing full coverage of our 60,000 seat football stadium and it's a real mess. In some ways a stadium would actually be easier than a venue the size of
Disneyland.
