P. P will be selected for the following conditions:

P.P parent is the best parent

P.P link SNR is at least 20dB (In this case, other parents, however good, are ignored)

P.P has link SNR between 12 and 20 dB, but no other parent is significantly better (SNR more than 20% better). For lower than 12dB SNR, P.P configuration is ignored

P.P is not blacklisted

P.P is not in silent mode due to DFS.

P.P is in the same Bridge Group Name (BGN). If no other parent available in the same BGN, the child will join the P.Pusing the default BGN

Interferers detected by Clean Air on 2.4 GHz include

AP1552 offers Clean Air in Bridge (Mesh) Mode -there is no other mode available

No Clean Air on 5 GHz (Backhaul)

No Monitor Mode

No Spectrum Connect Mode (SE-ConnectAP)

For Your Reference (Software Rel. 7.0.116.0 onwards)

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

Page 52: Design and Deployment of Outdoor Mesh Wireless Networks

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco PublicBRKEWN-2027 60

PMAC Merge in Outdoors

Cluster Center - is the closest AP to the device

After PMAC signature merging – one can identify which APa can hear the device

PMAC Convergence and Merging depends upon

Density of the Sensors

Quality of the observed classification

CleanAir Licensing

A CleanAir AP is the license no special controller license required – will work with WCS Base

Adding an MSE – requires 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

RF Nature: Not an Exact Science, Especially in Unlicensed Spectrum

Mesh: AP-to-AP Backhaul Distance Capability should be 2x AP-to-Client

WiFi Network Planning Involves:

Site Survey to Identify: AP Location & Height, Line-of-Sight (LoS)/Partial LoS, Interference, Access to wired backhaul (i.e. Max # Hops), …

Client type (Smart Phones, Tablets, Laptops, …)Weakest Link typically would be the Uplink on a Smart Phone

User Experience: Minimum Throughput to User, Type of Applications (Internet, Video, Gaming, ….)

CAPEX & OPEX available for project; Match to type of Service, Robustness of Coverage, …

Regulatory Considerations; different countries allow different Tx power at different Frequency Bands.

Type of AP Used: AP1552E&H (External Ant.), AP1552C&I (Integrated Ant.)

AP1552E, AP1552H : Antenna Gain 2.4 GHz (4 dBi), 5 GHz (7 dBi)

AP1552C, AP1552I: Antenna Gain 2.4 GHz (2 dBi), 5 GHz (4 dBi)

DFS required by Regulations to allow

WLAN to share the 5GHz band with Radar

All Cisco products are compliant

Best Practices for Radars:

Do a Survey and contact the local

authorities to know if there are radars

nearby

Use “Full Sector Mode” that prevents

MAPs to be isolated after detecting a

radar

Correctly mount the APs (spacing

and antennas alignment)

Remove the radar affected channels

from the Controller channel list

Bridge Group Name (BGN)-Sectorization

Logically groups APs and controls the association of the radios

For adding capacity we recommend that you have more than one RAP in the same sector, with the same BGN, but on different channels

A factory default BGN is empty (NULL VALUE). BGN is a string of Eleven characters maximum

Mesh APs with incorrect BGN, can still join a running network using BGN as the word “Default”

AP using “default” BGN

Associate clients, and forms mesh relationships

After 15 minutes APs will go to SCAN state rather than Rebooting
