Best Practice Guide for Video
Application: Deployment of Video (Multicast or VoD)
over Wi-Fi in Hotel environment
Equipment:
ZoneDirectors
ZoneFlex 7962, 7363 Dual Band Access Point
MediaFlex 7111 Adapters
Basic Configuration:
Dedicate common SSID for data (2.4 GHz)
Dedicate AP unique SSID for video (5 GHz)

Configurations to optimize video
1. Turn off background scanning
2. Channel Management
3. Separate SSIDs to segment the 7111s
4. On 7111 turn off Adapter Management Self Configure
5. For the multiple 7111s that are connected to a 7962, the one with
the slowest zap throughput is the throughput you should estimateto get (being conservative).
6. Change Directed Broadcast Threshold to a value larger than thenumber of maximum client associated to the AP
7. Disable Mesh
8. For larger # of Adapter configuration, you can use the Quick-
config Adapter Script that we have created

Turn off background scanning
Recommendation is to TURN OFF background scanning
With background scanning ON, the AP will go away andscan every 20 seconds for a period of 30 msec. Duringthis period, there is a potential of video disturbance
Current software release locks the background scanning
of 5 & 2.4 GHz option together. Turning off backgroundscanning disables on both frequencies

5 GHz Channel Management
Manual Channel Selection
With automatic channel selection, the video can be interrupted
during channel optimization
If possible, use one of the higher powered channels (country
dependent)
US: 149 or higher (until 5 GHz DFS is approved)
EU: 100 or higher
40 MHz Channel
For proper video distribution,
we recommend that you
allocate 40 MHz for each
channel. The 5 GHz band hassufficient number of channels
for re-use even in the case of
40 MHz setting149

Separate SSIDs to segment the 7111s
Use different SSIDs amongstAPs to statically mapdifferent 7111s to thedesired AP.
Different SSIDs betweenfloors
Different SSIDs betweendifferent areas of thedeployment

Throughput Estimate and Streams
calculations
For multiple 7111s that are connected to a 7962, theone with the slowest zap throughput is the throughputyou should estimate to get (being conservative).
Estimate the overall supported throughput by running
zap and find the 99.5% tile Calculate the number of supported video streams by: # of Video Streams = Overall supported throughput /
(bandwidth per video stream)
Typically 3 -4 Mbps for SD & 8 12 Mbps for HD
Use 40-60 Mbps as rule of thumb for overall supportedVideo Throughput

Turn off Adapter Management on 7111
Adapter Managementis used to provideauto-provisioningcapability (to 7811)
Turning off this
feature will allow theuser to individuallyconfigure the 7111 tothe specific SSID

Disable Mesh
Under most scenario, we should disable Mesh, as
it reduces the bandwidth and also the Mesh
topology changes can potentially cause video
disruptions Root AP performs periodic scanning

Tune Directed Broadcast Threshold
Change Directed Broadcast Threshold to avalue larger than the number of maximumclient associated to the AP
Configuration (for increasing threshold to 10)
In a standalone AP set directed-thr wlanX 10 for each WLAN
In a ZoneFlex environment where the Zone Director ismanaging APs
enter the ZD CLI command: set_qos wlan
directed-threshold 10 for each WLAN.

Use Quick Configuration Adapter Script
For larger # of Adapter configuration, you can use theQuick-config Adapter Script
The script provides the following automatedconfiguration steps:
