I'm conteplating taking on a project to install a wlan for a 70,000 sq ft hall. The second requirement is that it will need to support a couple hundred simultaenous users. My question is, what would be the most cost effective solution for such a wlan? I was thinking using a 4100 with a few APs. What do you guys recommend. Also something that wouldn't be a pain to configure. I'm farily new to wireless on such a scale..
