Wireless in stadiums and other large venues

With the memory of the Super Bowl fresh, it is natural to think about wireless in a stadium.  The Levi stadium in Santa Clara has a wireless network that is nicely done.  It was done by Aruba networks with APs under the seats to deliberately limit the cell size http://www.mobilesportsreport.com/2014/08/stadium-tech-report-aruba-networks-chief-designer-on-building-the-ultimate-stadium-network-at-levis/   In other cases absorption from bodies is bad, but in this case it is good.   http://www.arubanetworks.com/wp-content/uploads/stadiumRFfund.pdf.  When planning your own implementation make sure to review some of the wireless vendor solutions already out on the web.  For the case of Aruba it may be found at http://www.arubanetworks.com/solutions/lpv/
