I recently saw a demo on Ekahau's Connect/Sidekick 2 solution. Expensive, but seems like an interesting long-term investment, especially if you do large Wifi Networks often or you hate/wasting time on Wifi mapping I have a Sidekick 2 along with Ekahau AI Pro. Just load up a map and waypoint along your path, set a gateway to ping, and get tons of telemetry about your wireless network environment.
