• 1 Transmitter & 1 Receiver (per band) – up to 54 Mbps• Early diversity Access Points use two antennas with one radio per

band sampling each antenna - choosing the one with the least multi-path distortion and then transmitting back on the same antenna

• Cisco 802.11a/b/g/ Access Points start off favoring the right (primary antenna port) then if multi-path or packet retries occur it will sample the left port and switch to that port if the signal is better.

• Since speeds were only 54 Mbps 10/100 ports were fine

• Since PoE was 15.4W the radios had plenty of power the higher gain antennas above 6 dBi were permitted

• Both Indoor/Outdoor was permitted without frequency restrictions 802.11n introduced restrictions for outdoors creating the 3502P

Spatial Multiplexing – A method for boosting wireless bandwidth by taking advantage of multiplexing which is the ability within the radio to send out information over two or more transmitters concurrently (in parallel) known as “spatial streams”.

TxBF – Transmit beam forming – Signals that are sent on separate antennas that can be coordinated (think time shifted) to combine constructively at the receive antenna.

MRC – Maximal Ratio Combining a method that combines signals from multiple antennas taking into account factors such as signal to noise ratio to decode the signal with the best possible Bit Error Rate.

802.11n “Things that never really got much traction”• Greenfield header (pure 802.11n, for networks with no 802.11a/b/g stations) by the way

this is a bad idea as you want to be a good RF neighbor. FYI - Greenfield will not be supported in 802.11ac.

• 4 Spatial streams for up to 600 Mbps (assuming bonded 40 MHz and short 400ns GI) just too many issues (lack of clients, PoE considerations etc.) FYI .11ac 3-SS Wave-1

• Channel bonding in 2.4 GHz for enterprise (just not enough channels) as you can only do so much on 2.4 GHz as there isn’t that much spectrum. FYI- 802.11ac is 5 GHz only

• Explicit beam-forming (clients really didn’t support this) FYI- Supported with .11ac

• Dual CTS protection (AP send to CTS when using Space Time Block Coding, STBC, which extends the range of the cell: one CTS for non-STBC stations (short range), and one CTS for STBC stations (longer range) FYI – New protections added with .11ac


• Up to 3 radios per band – speeds up to 300 Mbps

• 2.4 GHz (802.11b/g/n) and 5 GHz (802.11a/n) – Support for 2-spatial streams

• Lots of antennas (typically 6) three for each band

• Antennas are single band single radiating elements identified by black and blue (5-GHz) colors

Security Module & 802.11ac Module

Review – 802.11n “G2” second generation APs

Note: New .11ac module brings increased performance to the AP-3600 Access Point up to 1.3 Gbps


So let’s talk about 802.11ac – Wave1 The Wi-Fi Alliance (WFA) is looking at Wave 1 today with the main features implemented being:

• Channel Bonding 80 MHz (mandatory)

• Faster modulation 256-QAM (optional)

• Ability to receive 1,2 & 3 Spatial Streams tested

- 2SS is mandatory for non-battery-powered APs

- Only 1SS is mandatory for battery powered AP’s and clients

• WFA’s focus is on 80 MHz, 1-3SS and 256-QAM with WFA compliant products likely sporting a new Wi-Fi Certified logo

802.11ac is happening in stages Referred to as “Wave-1 and Wave-2

Wi-Fi Alliance logo should look something like this

So let’s talk about 802.11ac - How is it like .11n?802.11ac (Wave-1) introduces 256-QAM

Faster throughput happens when you can use more complex Modulation Coding Schemes (MCS) rates

802.11n 1-ss MCS up to 64-QAM64-QAM uses 6 bits per symbol 802.11ac 1-ss MCS supports 256-QAM

256-QAM uses 8 bits per symbol (up to 4x faster)


Beamforming – What did and didn’t happenRemember 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.


Beamforming Efficiency MechanismsSingle 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


So let’s talk about 802.11ac - How is it like .11n?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)


So why is channel bonding so important? 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


Channel Bonding Wave-1 and Wave-2 .11ac MCS Rates @ 1-spatial stream -- (Wave1) typically supports up to 3-ss (Wave-2) up to 8-ss


Just one more EYECHART802.11ac (Wave-2)Up to 8 spatial streams.

.11ac MCS rates (unlike 802.11n) don’t exceed 0-9 -- but rather it is 0-9 and thenyou call out how many Spatial Streamsso a chart like this is quite extensive.

Depicted to the right is only streams 2 & 3out of the 8 possible spatial streams.

1 stream (80MHz) is 433 Mbps2 stream (80MHz) is 866 Mbps3 stream (80MHz) is 1300 Mbps

1 stream (80MHz) is 433 Mbps2 stream (80MHz) is 866 Mbps3 stream (80MHz) is 1300 Mbps

(Now let’s drop it to ~70% MAC efficiency)

So assuming ~70% MAC efficiency*What’s the real expected throughput?


Let’s talk about 802.11ac - How is it like .11n?So if I bond what’s those channels look like?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


Let’s talk about 802.11ac - How is it like .11n?So if I bond what’s those channels look like?ETSI and Japan channel allocation plan

80 MHz bonding (Wave-1) 160 MHz (Wave-2)

Note: Efforts are underway globally to expand the number of channels in the 5 GHz band.China probably is progressing a bit quicker then others but everyone sees the need.


What’s the plan to get more channels (future)

• In the US there are currently 22/10/5/1 channels with bandwidth 20/40/80/160MHz channels

• With opening up of 5.35-5.47GHz & 5.85-5.925GHz, the number of channels increases to 34/16/8/3

• If the industry manages to take back the TDWR channels, the number of increases to 37/18/9/4

Since we are talking about the future (Wave-2)

• A single GbE cable is fine for (Wave-1) (Wave-2) will exceed GbE speeds so for now, it is recommended for new installs requiring (Wave-2) that you pull two CAT6a cables until this standard is better defined.

• A pair of CAT6a cables allows you to fall back to using 2 GbE ports for some iterations of (Wave-2) if required ?. 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)


How about Multi-User MIMO (MU-MIMO)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.

Three separate and discrete radios…

The two 5-GHz radios (integrated and module) work in TANDEM and use same SSIDs so they do not compete with each other. They work in concert to support same channels (with internal radio taking lead on frequency selection) and the module performing the AC “overlay” AP has a dual-core uP with the radio module on one core supporting up to 50 .11ac clients


Power over Ethernet – AC Radio Module

All 3 radios (module + 2 internal radios) requires 18W (802.3at) source “PoE +”If the switch doesn’t support this - the module will be disabled by (default) until a proper source of power is applied such as PoE injector Cisco AIR-PWR-INJ4 or local 48VDC supply AIR-PWR-B

To get the module running on .3af PoE (15.4W) it is possible to disable the 2.4 GHz radio & restart.

.11ac clients? Any issues so far?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


How can I tell the .11ac client is on the .11ac radio?

The client should report 11ac rates if connected to the 11ac module – If no module present the .11ac client should drop to .11n rates and connect to slot 1 (internal 5-GHz radio)


Sniffers?

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.


Client cell sizes similar between .11n and .11acThere are so many data-rates in .11ac

Using the internal .11n radio on the AP-3600i. 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

Client - Dell E6430 Broadcom 3-ss client installed using Windows 7

We removed the Intel Ultimate 6300We 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 and the .11ac Radio ModuleRRM 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.


802.11ac and RRM – Yes RRM will need improvement.• 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


Beamforming and the .11ac Radio ModuleECBF 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)


Troubleshooting the .11ac moduleThings 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

Understanding mounting installation options

While Bracket-3 does not work with the AP-700 you can still mount the AP-700 in the center of the tile if needed using an electrical box approach. See 3600 deployment guide for more details

Although Bracket-7 is smaller the T-Rails (grid clips) are compatible with both brackets as the hole patterns are the same


Even the AP-700 - Still has advantages over Aruba…

Aruba AP-135 Take-away – You can’t stick aPaper plate through our APWe have no exposed holes on top.

Cisco AP-700

AP-700 uses same ceiling hardware and electrical box compatible METAL BRACKET for more mounting options.


AP-700 Mounting Information• Each AP-700 ordered includes:

o New AIR-AP-BRACKET-7 (only compatible with AP-700)

o Existing AIR-AP-T-RAIL-R or AIR-AP-T-RAIL-F

o Optional AIR-CHNL-ADAPTER at additional cost ($5 USD).

• The table below details what mounting options are supported with AP-700 series.


Antennas and how things radiate AP-700i…

(2) Discrete single band 2.4 GHz single radiating element antennas(2) Discrete single band 5.0GHz single radiating element antennas

3 dBi @ 2.4 GHz

5 dBi @ 5 GHz(Measured peak)

VSWR is better then 2:1

Isolation is at least

20dB @ 2GHz 30dB @ 5GHz


Antennas and how things radiate AP-700i…2.4 GHz antenna element number 1

2.4 GHz 3 dBi (PEAK)

Patternis fairly uniform

Note: This is early information

I don’t have them in Cisco format as it was not characterized at the Cisco Richfield Ohio Facility


Antennas and how things radiate AP-700i…5 GHz antenna element number 4

5 GHz 5 dBi (PEAK)

Patternis fairly uniform

Note: This is early information

I don’t have them in Cisco format as it was not characterized at the Cisco Richfield Ohio Facility


A few things you ought to know about the AP-700Take-away – it is NOT an AP-3600

Take-away – AP700NO “In-Tile” mount

Take-away – The existing brackets 1-3 are notcompatible with this physically smaller AP

Unrelated-Take-away - The first release of the AP-700 will support DFS just not in US (FCC) it’s a time to market thing but it will


Key TakeawaysThe Key Takeaways of this presentation were:

• Takeaway 1 – 802.11ac is an ENHANCEMENT based on elements of 802.11n

• Takeaway 2 – 11ac module works in tandem with the integrated 11n radio

• Takeaway 3 – GigE (1 cable) is all that is required for Wave-1

• Takeaway 4 – 11ac clients are steered to the 11ac module (slot-2)

• Takeaway 5 – Always LEAD with 3600 or 2600 (come down to 1600 or 700 if needed)

• Takeaway 6 – AP-700 position only in ULTRA-PRICE sensitive deals
