Capturing 802.11ac Data


Published on

Watch the full ondemand webcast here:

Gigabit wireless is quickly becoming a reality. With ratification of the 802.11ac specification right around the corner and a wide range of commercial 11ac devices already available based on the draft standard, the pressure is building to have a network monitoring and analysis system in place that can handle the demands of gigabit wireless. Is your wireless LAN (WLAN) network analysis system up to the task? Can it even capture 802.11ac traffic, let alone run at the speed necessary to handle gigabit data rates? Join us as we uncover the demands that 802.11ac places on WLAN analysis, and see a demonstration of the only complete WLAN analysis solution for 802.11ac – both analysis AND data capture.

  4. 4. 802.11ac vs. 802.11n © WildPackets, Inc. 4
  5. 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 /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 #wp_80211ac © WildPackets, Inc. 5
  6. 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 #wp_80211ac © WildPackets, Inc. 6
  7. 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 #wp_80211ac © WildPackets, Inc.
  8. 8. 802.11ac Basics © WildPackets, Inc. 8
  9. 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 #wp_80211ac © WildPackets, Inc. 9

  21. 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! #wp_80211ac © WildPackets, Inc. 21
  22. 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
  23. 23. Now Let’s Review #wp_80211ac © WildPackets, Inc. 23
  24. 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. 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 #wp_80211ac © WildPackets, Inc. 25
  26. 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 #wp_80211ac © WildPackets, Inc. 26
