Yes, in large deployments where many shop floor devices (iPhones, tablets, kiosks, handheld barcode scanners, equipment monitoring, etc.) are moving around from AP to AP they build up the cache table which begins making them get a little flaky after a while. I've been in shops all around the U.S. where they don't use as much Wi-Fi moving devices, primarily stationary so this does not pose as much of an issue. However, when you have management team members, supervisors, inventory control specialists, etc. moving all over the shop their devices change APs frequently and sometimes cause more cache table entries and thus the connectivity problems occur. However, we are way off topic for this thread...LOL.
