Cisco CleanAir for 80-MHz Channels
With Cisco CleanAir® for 80-MHz channels, Cisco has fundamentally retooled the
award-winning CleanAir technology to support the entire 80-MHz channel supported
by 802.11ac while providing the same level of granularity and accuracy of RF
interference detection as before.

award-winning CleanAir technology to support the entire 80-MHz channel supported
by 802.11ac while providing the same level of granularity and accuracy of RF
interference detection as before.
The benefit of an 80-MHz channel is the potential to double usable throughput in
comparison to the 40-MHz-wide channel used by 802.11n. However, a wider RF
channel is also more susceptible to interference. In other words, 802.11ac devices
“hear more” than 802.11n devices, primarily due to the wider channel support.
Not all 802.11ac access points perform well in the presence of interference. With
the increasing number of clients per access point, number of access points in a
given wireless network, and number of wireless networks themselves, wireless
network operators and administrators are challenged to maintain performance when
interference exists. In brief, for high-performance and high-density environments,
spectrum intelligence continues to matter. When interference can be detected and
identified, it can be mitigated.

For these reasons, Cisco CleanAir technology is a key feature in Cisco’s HDX
solution. Because of the increased channel bandwidth for 802.11ac networks, and
the increasing density of wireless networks, CleanAir is essential to help assure that
no significant degradation or suboptimal performance results from the migration to
802.11ac and the concurrent growth in high-density deployments.

ClientLink 3.0
Cisco ClientLink 3.0, as part of HDX, can perform Cisco’s patented beamforming
technology with 802.11ac clients as well as 802.11a/g/n clients. In fact, ClientLink 3.0
complements standards-based Explicit Compressed Beamforming Feedback (ECBF) in
which more and more 802.11ac clients will actively participate. ClientLink 3.0 improves
the downstream performance and throughput from the access point to the client as
well as improving the upstream performance and throughput from the client to the
access point. This improves the quality of the connectivity between client and access
point, resulting in a more stable network connection.

ClientLink 3.0 will also benefit the wireless network transition from 802.11n to
802.11ac. Every new wireless standard adoption comes with the challenge of
a mixed-device environment. We saw it when running 802.11n with the mix of
802.11ac. Every new wireless standard adoption comes with the challenge of
a mixed-device environment. We saw it when running 802.11n with the mix of
802.11a/g devices, and we are now seeing it with 802.11ac and a more convoluted
mix of 802.11a/n devices. There is a high chance that your office or enterprise will
have a blended presence of legacy 802.11a, 802.11n, and 802.11ac client devices
coexisting together. ClientLink 3.0 helps solve issues involved in mixed-client networks
by enabling higher data rates for both legacy and newer clients, even when they are
connected to the same access point. With ClientLink 3.0, networks will be able to
enjoy the benefits of 802.11ac with a more efficient and higher-performing Wi-Fi
experience.

Turbo Performance
Turbo Performance with HDX technology allows the supporting access points to scale
to 60 clients or more, with each client running media-rich video or interactive traffic,
without any performance degradation. This is especially important in networks with high
client density, in which some competitors fall short at 10 or 20 clients.

client density, in which some competitors fall short at 10 or 20 clients.
Turbo Performance is important with 802.11ac because of the higher data rates,
which equate to more packets per second (PPS) flowing through the access point.
For example, with 802.11n, an access point might have had to push 30,000 1500-
byte packets per second (PPS) through the access point’s data plane. Today, with
802.11ac, that could be 75,000 PPS or more. More PPS means more load on the
access point’s CPU, so to really keep up with the demands of 802.11ac, a redesigned
access point is needed.

With Turbo Performance, Cisco has fundamentally retooled its access point design
specifically for 802.11ac. The result is much less CPU-intensive processing and a
much more efficient packet scheduler delivering 802.11ac speeds at a much larger
scale than the competition. 802.11ac allows for speeds never before seen on a Wi-Fi
access point. Cisco understood the demands caused by these increased speeds and,
with HDX Turbo Performance, has fundamentally reworked the data plane in order to
enable unrivaled 802.11ac performance and scalability.

Optimized Roaming
Optimized Roaming allows clients to roam more intelligently and cleanly between
access points as well as between unlicensed and licensed cells. It addresses a
fundamental problem called stickiness in which the client stubbornly stays connected
to an access point that it connected to earlier, even though the client has physically
moved closer to another access point.
