What is SDN?


A Typical Network


A Typical Network Requires Effort

Manual CLI/Scripts

Box-by-box

Human middleware


A Typical Network Element

Every element has its own

intelligence & configuration

Every vendor defines unique ways

to configure the box

Mgmt PlaneTelnet, SSH, SNMP,

NTP, SYSLOG, HTTP, FTP/TFTP

Control PlaneNetwork topology, ACLs,Forwarding & Routing, QoS, Link Management

With SDN Wi-Fi, you achieve

Holistic visibility of wired and wireless networks

No Vendor Lock-in (mix and match)

Predictable Quality of Service across the unified network

Insight/Analytics across the unified network

Diagnostic/Troubleshooting across the unified network

Unified Wired Wireless is the PROBLEM that SDN for

Enterprise can solve, and can solve very well!

The Latest 802.11 standard…

802.11ac and why fully utilising

it’s capabilities is important!

• Higher throughput for legacy and new devices

• Latest standard

• Better ROI

• Improved end-user experience

• Greater density of devices

Wider Channel Widths for Bigger

Payloads

The “DFS Channels” (Dynamic Frequency Selection) FCC Rule # 15.407(h)(2) requires that products operating in the UNII-2 and UNII-2 extended bands

(5.25-5.35 GHz and 5.47-5.725 GHz) must support Dynamic Frequency Selection (DFS), to detect

and automatically adjusts channels to protect WLAN communications from interfering with military or

weather radar systems. All WLAN products that ship in Canada and the US on or after July 20, 2007

must meet the DFS for FCC requirements.

Thank You

Power and space challenges are still the same

• Don’t expect more than 3 data streams soon (-)

• Higher rates available at ranges closer to the AP (-)

• Higher throughput efficiency mean less time (power) spent for transmit (+)

• Users will still observe greater net throughput (+)
