At-A-Glance
With Optimized Roaming, a Cisco access point continuously evaluates the quality
of the Wi-Fi connection for each associated device and can actively disconnect a
device upon detecting that the device is moving into a region of poor coverage. This
disconnection forces the client to enter its scanning mode much earlier than it ordinarily
would, terminating a connection that is becoming essentially unusable and allowing the
client to connect to an access point with better performance.

device upon detecting that the device is moving into a region of poor coverage. This
disconnection forces the client to enter its scanning mode much earlier than it ordinarily

client to connect to an access point with better performance.
Optimized Roaming not only benefits the end user but also improves the overall
performance of the access points and therefore the experience of other users. A
client that is gradually degrading in performance (and possibly degrading faster
than it can dynamically rate-adapt to or compensate for) may cause a large number
of retransmissions, which consume airtime. If enough clients are being sticky, the
performance of the access point can be degraded. Therefore, sticky clients that
maintain poor connections can easily affect well-behaved clients.

Optimized Roaming helps prevent a negative experience for Wi-Fi users by monitoring
the connection quality of all devices and proactively prompting poorly performing client
devices to seek a better connection much sooner.

RF Noise Reduction
RF Noise Reduction allows the access point to be more efficient in its use of the
RF spectrum and possibly to recycle channels. This feature allows neighboring or
adjacent access points to use the same channel to increase overlay density and
mitigate configuration errors. With RF Noise Reduction, it is possible to deploy more
access points in a given area to meet strenuous service-level agreements (SLAs).
This is important for networks with extremely high client density, because it allows the
deployment of additional access points to handle the higher client demand. RF Noise
Reduction will be available in a future release.

Summary
If you are an enterprise IT manager and you are considering deploying 802.11ac for
your wireless network, you must ask yourself if all 802.11ac access points are alike.
802.11ac has some great benefits, such as wirelike speed and the ability to handle
a high concentration of clients. However, there is more to consider when deploying
802.11ac. For instance, how do you handle RF interference now that 802.11ac
supports 80-MHz channels? Will legacy devices such as 802.11a/g/n allow you to
achieve the best performance that 802.11ac is capable of? How can you ensure that
your users get the best wireless performance when they roam across a building? And
lastly, as more clients join the network, is your performance going to suffer? These
are all valid concerns that Cisco addresses with its HDX solution. HDX is a necessary
component of a wireless network, complementing 802.11ac while helping ensure that
you get the best performance out of your wireless network.
