CleanAir Recommendations for Outdoors AP Density recommendation for CleanAir remains the same as normal Mesh AP Deployment (800/1000 feet cell radius) APs should be RF neighbors for any possibility of Merging (spatial proximity) Location Resolution in the Outdoors is to the nearest AP Devices generally are located near the AP which is physically closest to the device Outdoor Custom Calibration possible from 7.0.116.0 onwards Location error may double without custom calibration model Installation with a low density of sensors has the possibility of having duplicate entries of interferes Mixing CleanAir (AP1552) and Legacy AP’s (AP152X) operating in Local Mode (serving clients) is Not supported – nor is recommended BRKEWN-2027 © 2011 Cisco and/or its affiliates.
