When the WC7520 makes senseBasic, affordable centralized wireless management
+ Basic managed wireless is required, mainly for indoor coverage
+ Multimedia content is not a primary use case
+ There are no plans to upgrade to 802.11ac+ There are no plans to deploy managed outdoor Access
Points+ Best fit is for small and medium organisations without a
high concentration of users.
Ideal vertical targets: Primary schools, kindergarten, assisted living centres,
museums where wireless traffic usage is light, warehouses with low to medium traffic
Advanced, performance based wireless management
• Secure, enterprise class control
• Scale from 2 - 50 APs per
controller
• Stack 3 Controllers to support
upwards of 6000 devices
• Stack for redundancy /
resiliency
• 802.11ac ready
• Premium 11n AP support
• 10 AP incremental license
ProSAFE WC7600
Advanced, high performance based wireless management
• Secure, enterprise class control
• Scale 2 - 200 APs per controller
• Stack 3 Controllers to support
upwards of 36,000 concurrent
connections / redundancy
• 802.11ac ready / Premium 11n
AP support
• 10, 50, 100 and 200 AP

When the WC7600 & WC9500 makes senseHigh performance, centralized wireless management
+ Rich multimedia content over wireless is important
+ Dedicated ‘in-room wireless’ Access Points required (WN370)
+ Deployments with a high density / concentration of wireless clients
+ Premium AP management required (WNDAP620 / WNDAP660)
+ Automated service load balancing for heavily congested areas / peak usage needs / areas of high interference allowing traffic to move from 2.4 GHz to the less congested 5 GHz band
+ Migration to 802.11ac is required+ Outdoor Access Point management is needed
Ideal vertical targets: Hotels up to 150 rooms, high schools, colleges with up to 2,000 students, campus and dense
warehouse deployments – places where heavy wireless traffic is expected

ARP SuppressionMaximizes airtime utilization
+ ARP Suppression stops ARP broadcast packets from taking precious airtime by suppressing ARP packets on APs that do not have the specific clients in the range
Who is Tom? I am Tom
ARP
More Airtime, Better User Experience
N.B. Airtime Fairness gives equal amounts of air time (instead of equal number of frames) to each client regardless of its theoretical data rate. This will ensure higher download speed to latest devices when slower devices are connected to the same AP.
Bandsteering
+ What is it?+ Dynamically moves clients from a congested frequency (typically 2.4GHz) onto
a less congested one (5GHz)
+ What does this mean for my network?+ Adds capacity, by reducing network congestion for more balanced network
bandwidth usage
+ Clients can be instructed to only join 5GHz even if 2.4GHz capable

High Density Client AreaLoad Balancing to meet excess load
Set the max client for each radio at 25Set the minimum RSSI threshold to connect at 40 (-73 dBm)
21
High Density Client AreaTurn down power, not up
+ Often mistake is turn up AP power, but that will cause co-channel and adjacent channel interference
+ Turning 2.4 GHz output power to ½ or ¼ and 5 GHz output power to ½ and add more AP is better solution
22
High Density Client Area (WC7520&WC7600)Enable Automatic Feature
High Density Bandwidth:
High: With this option RTS/CTS retrys will be disabled, and should be used when lots of clients on same AP radio are doing high bandwidth application like watching streaming video.
Low: With this option RTS/CTS based retry will be enabled, and AP cell range will improve.
Auto: The software will decide to do RTS/CTS retrys, By default, it will be optimized for AP cell range and RTS/CTS enabled.
