26. 26 Cisco Confidential © 2011 Cisco and/or its affiliates. All rights reserved. Remember this from 3600 TAC training? Well that was true… Channel Sounding and EBF method really didn’t make it into 802.11n Lots of channel sounding mechanisms and the industry could not decide at the time which one to use so everything was proprietary – EBF changed to ECBF Explicit Compressed Beam Forming This got a lot better with 802.11ac after a single sounding method was agreed upon.

27. 27 Cisco Confidential © 2011 Cisco and/or its affiliates. All rights reserved. Single User and Multi-user MIMO •  Channel sounding for SU & MU •  To make efficient use of a channel (and beam-form), stations need to know the channel characteristics – they can send test frames [sounding frames] of known structure, which allows the receiver to understand the channel specs, and beam-form or optimize back to the sender (AP or client). •  But for MU-MIMO, a unique sounding mechanism is important, and 11ac community agreed on a single sounding mechanism - Same mechanism is applicable for SU-MIMO – (This is the method the AC module uses to beam-form back to clients) •  ACK for MU •  AP polls each client for ACK. This adds overhead, but is more robust •  RTS/CTS for MU •  No new RTS/CTS mechanism is added for MU but the spec allows AP for proprietary mechanisms using conventional RTS/CTS Note: This still doesn’t benefit legacy and 802.11n clients so ClientLink 2.0 is still important. AP-3600’s 11ac module uses IEEE channel sounding on AC clients AP-3600 uses the integrated 11n radio and ClientLink 2.0 on N and legacy clients

28. 28 Cisco Confidential © 2011 Cisco and/or its affiliates. All rights reserved. What about channel bonding? Wave-1 allows up to 80 MHz channel bonding 802.11n can bond up to 40 MHz 802.11ac can bond up to 80 MHz (Wave-1) *up to 160 MHz (Wave-2)

MCS rates @ 1 Spatial Stream in Mbps New Phones such as the HTC One & Samsung S 4 have support for 802.11ac Wave-1 More than 1-SS requires that the client have more radios which draw more power. The goal is to enable devices to have more throughput with less battery draw Most mobile devices will use 1-SS Tablets & laptops can use 2-SS or more

Depicted to the right is only streams 2 & 3 out of the 8 possible spatial streams. 1 stream (80MHz) is 433 Mbps 2 stream (80MHz) is 866 Mbps 3 stream (80MHz) is 1300 Mbps

US- Theater – FCC channel allocation plan The 80 MHz channel uses two adjacent, non-overlapping 40 MHz channels. The 160 MHz (Wave-2) may be formed by adjacent or non-contiguous channels. TDWR channels not available today. Note: Channel 144 (in red) is new and likely more channels will be allocated in 5 GHz to hopefully allow for more than two channels @ 160 MHz (Wave-2) depending on the frequencies they may not be adjacent

If not needed, the other cable can be used to bring back the console port. CAT5e cables may be used or one of each for cost savings but not for 10GbE. •  Challenges - 10GbE PoE standardization - (additional cost of CAT6a cabling, cost decision may motivate the use of 1 CAT5e & 1 CAT6a - physical challenges 2x cables can be problematic given space in existing conduit pipes. (Wave-2) Minimum requirements for enterprise will likely include: 256-QAM, 3-SS and 160 MHz •  For Wave 2, initially it is expected that 160 MHz devices will appear with 1-3SS (typical) with perhaps 4-SS supported with likely data rates of 867-2600 Mbps. •  Likely data rates up to 3.5 Gbps PHY and over 2 Gbps MAC (IEEE approval late 2013)? •  Will require faster than GigE speeds requiring either 10GbE or perhaps two GbE cables / hybrid Future proofing new installations (cabling considerations)

37. 37 Cisco Confidential © 2011 Cisco and/or its affiliates. All rights reserved. Does it work? Any caveats? •  802.11ac MU MIMO is like 802.11n MIMO, except instead of one client, there are up to four clients •  AP does pre-coding for all the clients within the MU group simultaneously •  In MU pre-coding, when AP beam-forms space-time streams to one client, it simultaneously null- steers those space-time streams to the rest. •  All users’ MPDUs are padded to the same number of OFDM symbols •  MU-MIMO is technically risky and challenging: •  Needs precise channel estimation (CSI) to maintain deep nulls •  Precise channel estimation adds overhead •  Rate adaptation is more difficult •  Throughput benefits are sensitive to MU grouping WFA Wave 2 certification: • MU-MIMO Null-steering:To send data to user 1, the AP forms a strong beam toward user 1, shown as the top-right lobe of the blue curve. At the same time the AP minimizes the energy for user 1 in the direction of user 2 and user 3. This is called "null steering" and is shown as the blue notches. Same logic applies to red and yellow beams.

USB clients appear a bit slow (and can have driver issues) Some clients seem to be having trouble using DFS channels @ 80 MHz Some client(s) that do not work well from the client steering perspective: -  Linksys AE6000 USB (CSCuf78329) Linksys 11ac USB client, under certain conditions, will appear to keep trying to connect to 2.4 radio (appears to be a client driver issue) even though we drop the probe/auth/assoc due to band select/client steering features. Sometimes it doesn't even send probe requests on 5G band. We are still working to see if anything can be done on the AP SW side that would overcome this client problem At this time, we cannot guarantee that this client adapter will associate to 11ac radio consistently, compared to other 11ac client adapters. Note: Most of the clients based on Broadcom chipset appear fine This one is a bit problematic based on MediaTek chip

Most .11ac devices today are based on Broadcom or Realtek No Omni-peek driver for those cards yet. * Assumes 70% MAC efficiency From Wildpackets… Our latest version of OmniPeek (v7.0) includes decodes for 11ac. But we are currently waiting for either a Ralink-based or Atheros-based external WLAN 11ac adapter to come to market before we can test packet capture with the devices.

We performed a quick cell size characterization with .11n rates using several .11n clients. When we switched to .11ac clients, and the .11ac radio module it performed similar @40 MHz with clients having a cell size similar to the .11n clients. Take-away .11n/11ac are similar rate/range but of course @80 MHz and 256-QAM you get a significant data-rate boost New facility in Richfield Ohio for competitive testing Note: We are still making changes from an RF and performance perspective – So it is a bit early for any real meaningful data

54. 54 Cisco Confidential © 2011 Cisco and/or its affiliates. All rights reserved. Comparison 802.11ac 3-ss client module radio vs. LinksysAP @ 80 MHz Client - Dell E6430 Broadcom 3-ss client installed using Windows 7 We removed the Intel Ultimate 6300 We found the Broadcom radio was bigger but fit fine in the slot to the left I have no idea why Linksys is slow as the RF reports high connection it just doesn’t seem to process the data quickly.

RRM w/.11ac (we are still making changes) right now the current RRM works ok, but it is making assessments based on the internal .11n radio and does not receive input from the .11ac module. That said, it does eventually figure it out if you give it time and enough RF activity. It is clearly not as robust as .11n RRM and it sometimes picks non-optimal channels initially but after awhile it does seem to settle on the correct channels especially if there are .11ac clients on the air and a modest amount of RF activity.

All rights reserved. •  So what are the challenges with RRM on Cisco WLCs? •  RRM today works by looking at 20 MHz-wide channels, and it’s easy to see activity (20 or 40) MHz •  BUT - for AC new methods to look at how the channel is comprised (20, 40, 80 and 160 <Wave2>) will need to happen - so for now it is a limitation, as we do not fully detect issues with conflicting 802.11ac settings… with the radio module. But it does work (best effort) but this will need to be tuned as we go along… •  New RRM (next gen) will need to take into account the different capabilities of each AP to determine the new channel widths and it will need to look at the PRIMARY CHANNELS as those are the most active when making the RRM assessment. Note: Primary channels are the anchor channels where the bonding begins

57. 57 Cisco Confidential © 2011 Cisco and/or its affiliates. All rights reserved. ECBF Explicit Compressed Beam Forming - The .11ac radio module uses this method of client “channel sounding” per IEEE 802.11ac specification. Note: The .11ac radio module does not support Cisco ClientLink 2.0, Cisco Compatible Extensions (CCX) or RRM. This is because the .11ac radio is not a primary interface as it is controlled by the active integrated .11n radio as a virtual or “blended radio” working in tandem so same SSID, channel etc. The primary radio still supports these features and controls when the 11ac radio module can transmit. This ensures it does not interfere with the primary integrated 11n radio providing isolation and maintaining receiver sensitivity. ClientLink 2.0 continues to enhance legacy and .11n clients, via 11n radio and will service what the .11ac radio doesn’t understand* *(for the most part) J

58. 58 Cisco Confidential © 2011 Cisco and/or its affiliates. All rights reserved. Things to look for if the module doesn’t come up Common issues arise because: •  Module isn’t screwed down tightly •  Not enough PoE power (requires 802.3at) 18W •  Not configured correctly •  Not understanding the radios operate “together” so you need to configure the radio in slot 1 (5 GHz internal) first •  Not understanding SSID’s for both 5 GHz need to be the same and all .11ac clients are sent to the .11ac module Things to look for if the module is not found: •  Console will report “module radio found and ok” •  Also console CDP message for Power “Power ok – HIGH POWER inline power source” •  Perhaps remove module – verify AP ok then reinstall •  Module should show up as “slot-2” •  If you suspect PoE (try AIR-PWRB or AIR-PWR-INJ4) •  Module with not work with AIR-PWR-INJ5
