Mesh APs

. AP Density recommendation for CleanAir remains the same as normal Mesh AP Deployment . APs should be RF neighbors for any possibility of Merging (spatial proximity) . Location Resolution in the Outdoors is to the nearest AP . 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 interferers . Mixing CleanAir (AP1552) and Legacy AP’s (AP152X) operating in Local Mode (serving clients) is Not supported – nor is recommended

PMAC Convergence and Merging depends upon . Density of the Sensors . Quality of the observed classification . RSSI from the interferer to the APs . RF neighbor list at the APs

Cluster Center - is the closest AP to the device

After PMAC signature merging – one can identify which APs can hear the device BRKEWN-2027 © 2012 Cisco and/or its affiliates. All rights reserved. Cisco Public 42 CleanAir Settings on Controller EDRRM & PDA off (WCS Identical Under Configure=>Controllers) by Default Wireless=>802.11a/b=>CleanAir

1 interferer = 1 CAS license

. A CleanAir AP is the license: no special controller license required . Adding an MSE – requires NCS or WCS Plus for location . CAS (Context Aware) license required for Interference location . 100 Permanent Interferers licenses are embedded in MSE. Interferer Licenses open up as Clean Air APs are detected, in stages of 5 per CleanAir AP . Interference and Client location functionally identical – and use the same license count . If license is 1000, and interferers are 500, then 500 clients can be displayed

2.4 GHz Interferers

3 Hops 2 Hops . Logically groups APs and controls the association of the radios 1 Hop . For adding capacity we recommend that you have more than one RAP in the same sector, with the same BGN, but on different channels . Having multiple RAPs with same BGN in an area is good for redundancy: when a RAP RAP goes down its MAPs will join a different sector with same name . A factory default BGN is empty (NULL MAP MAP VALUE). It allows the MAP to do the first association

. Each RAP on a different non adjacent channel, but same Bridge Group Name . Most of MAPs within 3 hops of RAP . If a RAP fails the MAPs belonging to the sector will go in SCAN mode and register to another MAP/RAP on a different channel/sector

2 miles

. Stranded: a MAP that is not able to associate and find a path to WLC . DEFAULT BGN (Bridge Group Name): Mesh APs with incorrect BGN, can still join a running network using BGN named “DEFAULT”. With “DEFAULT” BGN: MAP associates clients, and forms mesh relationships After 15 minutes APs will go to SCAN state rather than rebooting ‒ Do not confuse an unassigned BGN (null value) with DEFAULT, which is a mode that the access point ‒ uses to connect when it cannot find its own BGN ‒ . DHCP fall back: this features allow a MAP configured with a wrong static IP address to fall back to DHCP and find a WLC. If even this fails, AP then attempts to discover a controller in Layer 2 mode . FULL SECTOR DFS: DFS functionality allows a MAP that detects a radar signal to transmit that up to the RAP, which then acts as if it has experienced radar and moves the sector

. Given the nature of the outdoor environment and the lightly licensed spectrum being used for WiFi based outdoor MESH • Site Survey’s are important • Spectrum scans are equally important • You may not be able to remove the interference source • But you can design around it . Remember to also survey at street level where clients will be operating . If possible survey with either the client or “worst” client you expect to support . Time based surveys may also be required n months after deployment . Check for power availability . Do you have the permits?

Backhaul on Cable

Full Hanging rights Power from Stand

. Mount the Root AP to have a good view of the area to be covered . Understand RAP coverage. Use Directional Antennas for the RAPs on the Roof Tops. . Max recommended height for MAPs is 30 feet/10 meters . Recommend placing the APs at the same height . Minimum recommendation is 20~25 dB of SNR, RSSI of -67 dBm for all data rates, 15% cell overlap . Do not install the MAPs in an area where structures, trees, or hills obstruct radio signals to and from the access point
