I have 2 WLC 4400 controllers running 18.104.22.168 and a WCS server running 22.214.171.124. I have 60 AP's in a 480,000 sq ft warehouse/manufacturing environment. The AP 1242 support both voice ( on the 802.11a radion) and the Intermec 2455 mobile computer on the 802.11b side. The Intermec devices are having a huge problem staying connected as they drive through the warehouse. The AP's are every 80 ft. Does anyone know any special cofig parameters either on the intermec devices or the WLC controllers I need to make. All AP have been placed on maps and WCS is taking care of power and channel setting.
