5. 802.11n: Higher Throughput Improvements
Using MIMO
• Description
‒ Significant enhancements in data rate and range
‒ Uses new technologies including MIMO, channel
bonding, aggregation, short guard interval
• Use cases and market penetration
‒ Becoming the de-facto standard for commercially
available WLAN equipment – both consumer and
enterprise
‒ High-density deployments; multimedia
applications; forklift upgrades
• Compatibility and analysis implications
http://linksysde.custhelp.com/app/answers/detail/a_id/21194/~
/intermittent-wireless-signal-with-802.11n-routersand-access-points
‒ Backward compatible with a/b/g, but older technologies limit overall
improvements
‒ Not all network analysis software and hardware is up to the task
‒ Make WLAN analysis upgrades part of the overall 802.11n upgrade

6. 802.11ac: Very High Throughput <6 GHz
• Description
‒ Significant improvement over 802.11n –
higher throughput for less power
‒ Wi-Fi MIMO “multicast”
• Use cases and market penetration
‒ Commercial penetration for multimedia
over Wi-Fi
‒ WFA certification coming soon – based
on draft standard
‒ Will become the standard for 802.11
networking infrastructure going forward
• Compatibility and analysis implications
‒ Backward compatible with a/b/g/n, but older technologies limit overall
improvements
‒ Only operates at 5GHz, significantly reducing compatibility issues
‒ New speeds require new methods for detailed analysis

7. 802.11ac vs. 802.11n
• Gigabit speed wireless with approximately 3 times the performance for
the same power
• Better performance at any range with fewer dead spots
• More reliable connections for media streaming with beam-forming
• More Wi-Fi bandwidth on your mobile
• Only utilizes the 5 GHz band - much less prone to interference
• Backward compatible to 802.11 a/n

9. 802.11ac Highlights
• 802.11n “lessons learned”
• Wider channel bandwidths; More MIMO
‒ 80 MHz and 160 MHz channel
‒ Support for up to 8 spatial streams
• Multi-user MIMO (MU-MIMO)
‒ Multiple STAs transmit or receive independent data streams
simultaneously
‒ Downlink MU-MIMO (one transmitting device, multiple receiving
devices) included as an optional mode
• Low level MAC and RF improvements
‒ Beam forming improvements
‒ MAC modifications (mostly to support above changes)
‒ Coexistence mechanisms for 20/40/80/160 MHz channels, 11ac and
11a/n devices

21. USB Isn’t the Only Solution …
• I’m most probably NOT near the problem
• I still need supported devices
• I need supported devices that equal or exceed the
most capable devices on my network – now 802.11ac
• And, most importantly …
• USB MAY NOT up to the task!

22. USB
• USB 1.1 (Full Speed)
‒ September 1998
‒ 12 Mbps
‒ If you still have equipment with v1.1, get
something new!
• USB 2.0 (High Speed)
‒ April 2000
‒ 480 Mbps theoretical; 280 Mbps effective
‒ Extremely common for laptops in use
• USB 3.0 (Super Speed)
‒ November 2008
‒ 5 Gbps theoretical; 3.2 Gbps effective
#wp_80211ac
© WildPackets, Inc.
22
24. Doing Some 802.11ac Math
• Assume 2-antenna APs and STAs at 80MHz = 867
Mbps
• Assume effective throughput of 520 Mbps (60%)
• Assume you can “hear” 3 different APs
• If our analysis requires aggregating data from the 3
distinct APs together, the aggregated analysis
throughput is
• 1.56 Gbps
• Using USB devices, v3.0 is required for both the
WLAN adapters AND the laptop – not easy to find!
#wp_80211ac
© WildPackets, Inc.
24
25. And It Will Get Faster …
• Assume an 8-antenna AP, 4 2-antenna stations at 160
MHz using MU-MIMO (1.73 Gbps to each STA)
• Assume effective throughput of 1.04 Gbps (60%)
• If our analysis requires aggregating data from the 4
STAs together, the aggregated analysis throughput
is
• 4.16 Gbps
• This exceeds the 3.2 Gbps effect rate for USB 3.0, the
very best the market has to offer

26. So, What “Now”?
• As wireless approaches wired speeds, it’s time to
start relying on the wire
• Distributed analysis using deployed assets – APs –
is the only effective solution as wireless speeds
grow
• The choices:
‒ Remote PCap
‒ Custom Remote Adapters
