This document discusses challenging Wi-Fi deployments in warehouses, retail stores, stadiums, and outdoor areas. It provides tips for planning and surveying in these environments, including using directional antennas in warehouses to deal with high ceilings and shelves, performing on-site surveys between shelves to check for gaps in coverage, and using multiple survey adapters to quickly survey large outdoor and stadium areas with many access points and clients. Hands-on demos are also provided to illustrate Wi-Fi planning and analysis tools.
