3. Centrally Manage the Wireless Settings• Create AP profiles

• Schedule WLAN network or individual AP to go on/offline

• RF & Power management

• High Density Management

• Multi authentication scheme

• Seamless Fast Roaming (L2&L3)

• Cutomized Captive Portal

4. Centrally Monitor the Wireless Network

ARP Suppression (WC7600)Maximizes airtime utilization

10

+ 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 (WC7600)

+ 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

11

High Density Client Area (WC7520&WC7600)

Load Balancing to meet excess load

Set the max client for each radio at 25

Set the minimum RSSI threshold to connect at 40 (-73 dBm)

High Density Client Area (WC7520&WC7600)

Turn 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

13

High Density Client Area (WC7520&WC7600)

Enable Automatic Feature

14

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.

• Scale from 20 to 150 AP’s

• Full mobility / roaming support

• Guest Captive Portal

• Stack for redundancy / resiliency

WC7520

WC7510L

Product Detail

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.

25

Ideal vertical targets:

Primary schools, kindergarten, assisted living centres,

museums where wireless traffic usage is light, warehouses with low to medium traffic

ProSAFE WC7600

Product Detail

When the WC7600 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 in the future is required

+ Outdoor Access Point management is needed in the future

28

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

Pay As You Go LicensingTalk about clear pricing and TCO

+ What is it?

+ Each WC7600 comes with a default 2 starter AP license

+ To manage more than 2 AP’s, you need to order at least one WC10APL

+ Each WC7600 supports 5 x WC10APL license keys

+ What does this mean for my network?

+ Only pay for what you need, but you do need to remember to get the appropriate number of license needed (in block of 10 APs)
