Cisco Aironet 2700 – Looking at Ethernet ports
Same ports as AP-3700 except we
shortened the name to PoE and
added an additional (non-PoE)
auxiliary “AUX” Ethernet port*
with Integrated
802.11ac (3x4:3SS)
*Note: If powering AP on 802.3af (15.4W) this 2nd “AUX” port is disabled
© 2013-2014 Cisco and/or its affiliates. All rights reserved.
Cisco Confidential
18
Cisco Aironet 2700 – Why the extra AUX port?
Available to satisfy RFPs against the competition. Additionally; Verticals
(primarily education and retail) have a need to leverage the AP for end devices
such as projectors, phones, Point of Sale Terminals etc.– Note today this AUX
port is locally switched and not managed* This will be improved in later
releases but for now there is no LAG or any management of this port in the
7.6MR2 initial release.
*Note: Do not connect the “AUX” port to the same uplink switch as the AP.

power over(3x4:3SS)
15.4W
*Note: Port is enabled by default if running high PoE
and
there is no spanning tree protection right now all to be addressed later.


What version of code is being released? – FCS with 7.6MR2
What version of PI needs to sync? PI 1.4.2 and 2.1
Is spanning tree enabled on the AUX port? – No not at this time (later releases)
Can I plug another AP into the AUX port? – No, designed for end devices
Where does the traffic from the AUX port go? – 2nd port is locally switched
Can the AUX port be used for aggregation or greater T-Put (LAG)? – No
Is the AUX port manageable? – No it will be in later releases
Does this AP require 802.3at power? – Yes for best performance
Is throughput and range similar to the AP-3700? - Yes
Can I use all the same external antennas as AP-3700? - Yes
Is there an AP-2700P version? – No not at this time.

Why Do I Need 802.11ac
General thoughts
• Need for throughput, more smartphones/tablets only have 1 radio
but need high speed (you can almost double the speed of 11n
using 256-QAM, bonded channels and 1 radio)
• More need for streaming HD video in the enterprise
• Need to move large amounts of data quickly (example transferring
phone apps/contacts)
(more people are sharing music, apps, large presentations and
training videos)

25
General thoughts
•
802.11ac brings significant performance to the network and is logical
progression from
11b(11 Mbps), 11a/g (54 Mbps), 11n (600 Mbps), 11ac (1300 Mbps), <Wave-1>)
•
Beam-forming is now implemented in 11ac clients (but the AP also needs to be
11ac) to take advantage of the specification so it’s still lots of value in ClientLink.
Note: Cisco AP-2700 & 3700 can go beyond the 11ac specification with
ClientLink 3.0 and actually Beam-form to 3-SS 11ac clients as well as non-11ac
(.11a/g/n) clients

Elements of 802.11ac – Wave1 (The Basics)…
Here are the key elements of 802.11ac (Wave-1)
•
•
•
•
•
Support for faster modulation 256-QAM
Ability to use 1, 2 & 3 Spatial Streams
Extended bandwidth now up to 80 MHz
Beam-forming standard (for .11ac clients)
Enhanced methods of bandwidth sharing/allocation
Wi-Fi Alliance certifies 802.11ac products for interoperability @ 20/40/80
MHz, using 256-QAM and 1, 2 and 3 Spatial Streams

27
Understanding Channel Bonding
Bonding actually blends the channels together so you gain a small amount
of extra spectrum for data use
802.11ac introduced 80 MHz
One method to gain significant
throughput (2x or more) is to bond
the channels using more bandwidth.
This helps 1, 2 and 3-SS clients.
Single spatial stream clients also
realize physical size and battery life
benefits.

Elements of 802.11ac – Wave1 (The Basics)…
Here are the key elements of 802.11ac (Wave-1)
•
Support for faster modulation 256-QAM
• Ability to use 1, 2 & 3 Spatial Streams (can have up to 3
connectionsp on one device sending and receiving data)
•
Extended bandwidth now up to 80 MHz
• More bandwidth has been made available
•
Beam-forming standard (for .11ac clients)
• Traffic is optimized to each client

29
Why is channel bonding so important?
More than 1-SS requires
the client have more
radios which draws more
power from the battery.
Most smart phones and
some tablets will use 1-SS
More powerful tablets &
laptops use 2 & 3-SS
Newer phones
such as the HTC
One & Samsung
S4 have support
for 802.11ac
© 2013-2014 Cisco and/or its affiliates. All rights reserved.
The goal is to save
physical size and battery
life yet increase
throughput
How else can you get to
433 Mbps with one radio?

Upgrading Access Points 1:1 or another survey
Question: If I replace my Access Points with a newer 802.11ac Access Point do I have to
resurvey? Is the spacing the same between 11n and 11ac?
Answer: 11ac builds upon 11n, and cell sizes are similar. Years ago the guidelines were
1 per 5,000 Sq. Feet for data only and 1 per 3,000 sq. feet for voice & location.
We now recommend 1 per 2,500 sq feet and no longer break it down by applications.
Access Points have always had
similar heat maps – There will always
be slight differences but the goal is to
maintain uniform coverage with less
retries – But if you surveyed at 1 per
5K then you will likely need to
resurvey. It is always a good idea to
check coverage.

FM radio stations used fixed
channels but each channel has
2 “audio streams” in our case

Beam-forming Spatial Streams (ClientLink 3.0)
The extra radio “D” is used
to augment spatial stream
data and is used in beamforming
Note .11n had support for
beam-forming but was never
adopted so few if any clients
supported it.
Client-Link performs beamforming on legacy 11a/g/n
clients as well as 802.11ac
clients.

Note: Only Cisco APs can beam-form a 3-SS signal as it
requires 4 transmitters - most APs on the market don’t
have this additional radio for reliability and performance

The additional radio assists in both transmit and receive.
