Editor’s Note: This is the first of a four-part deep dive series into High Density Experience (HDX), Cisco’s latest solution suite designed for high density environments and next-generation wireless technologies. For more on Cisco HDX, visit www.cisco.com/go/80211ac.
CleanAir for 802.11ac: Why Spectrum Intelligence Still Matters
In wireless networking and communications, as with life, nothing good comes for free. It’s well known that the primary feature of the new IEEE 802.11ac amendment is support for an 80 MHz-wide channel. The benefit of an 80 MHz channel is the potential to double usable throughput in comparison to that of 802.11n using a 40 MHz wide channel.
However, what is less well known is that 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. It should be noted that this is not a flaw in the 802.11ac amendment, it’s simply basic communications theory.
Nevertheless, there is far more to building an 802.11ac access point than simply meeting the standard. Not all 802.11ac access points perform equally without interference. But more importantly, not all 802.11ac access points perform well in the presence of interference.
Furthermore, there is far more to deploying High Density wireless LANs than only considering the performance of individual access points. Read More »

A new year means new users and new devices. More devices means more network crowding. Mobile users demand bandwidth and speed, while the network is increasingly overwhelmed by the sheer number of devices. The networks of today and tomorrow have to be ready for high client density environments.
That’s why we’ve developed the Cisco High Density Experience (HDX). I announced HDX in a blog last October with a high level look at Cisco’s answer to handling high client density environments. Each feature in the HDX solution was designed specifically to alleviate the introduction of more clients, more bandwidth hungry applications to provide an unparalleled user experience.
Starting tomorrow we’ll kick off an HDX blog series to dive deep into the four key features that come with HDX:
- January 8: CleanAir
- January 13: Turbo Performance
- January 27: ClientLink 3.0
- February 10: Optimized Roaming

As children all around the world are eagerly anticipating Santa’s arrival on Christmas Eve, children in hospitals around the Americas were able to get their wish list in before the big day. This month, Cisco teamed up with several children’s hospitals with a Santa Connection project, which allowed children not well enough to visit Santa onsite to still communicate their wishes to him from their bedside using Cisco video.
I was able to work with one of these hospitals, Johns Hopkins Children’s Center in Baltimore, to augment the Santa Connection experience with a ‘Santa tracking’ app, which allowed children to know how close Santa was to making his virtual appearance to individual rooms in the hospital. An elf traveling ahead of the Santa Video team carried an iPad displaying a live webpage showing the location of the much-anticipated video visit. Here is a screenshot of the app experience:
Utilizing the Connected Mobile Experiences solution, which includes the REST APIs provided by the Mobility Services Engine (MSE), we were able to show the children where the Santa team was in relation to them -- with a Santa icon where Santa’s video crew was and a smiley face showing the child’s current location.

Now that the Holidays are upon us, and we look forward to 2014, the Cisco Small Business team continues to raise the Small Business networking bar with the introduction of the all new Cisco RV325. This Dual WAN, 14-port VPN Router, provides all of the same performance, security and reliability of the RV320 launched last June. Both routers are perfect for fast-growing small businesses or branch deployments. So if you are looking for more ports in the same enclosure, the RV325 is the Small Business router to take a look at.
RV320 and RV325
Like the it’s smaller sibling the RV320, the RV325 is a perfect match with the Cisco Small Business SG300 Series Switches and WAP500 Series Access Points. As you saw from my last Blog, the WAP551 and WAP561 boasts a nice feature-set including Captive Portal and Single Point Set-up. The WAP 551/561 are controller-less Access Points meaning additional hardware is not required. The SG300 Series offers a nice blend of features at an affordable price and are designed Small Business. It has most of the features that can be found in today’s Enterprise-class Switches.
This formidable combination makes for the perfect solution for that many Small Businesses and Organizations can take advantage of. Add in our portfolio of award-winning Cisco Small Business Services, and you have a solution that all that guarantees a positive experience from Cisco Small Business Team.
One Option for this solution is the newly launched 200 Series of Smart Switches. There are four new models including 10-, 24-, 26-, and 50-port switches. These Full Power PoE Smart Switches are a great alternative as they offer a generous feature-set, solid performance and even greater affordability.
SG200 Series PoE Smart Switch
Happy Holidays and Happy New Year’s from the Team at Cisco Small Business.

With the adoption of the Internet of Things and Internet of Everything, advances in mobility and next-generation Wi-Fi are driving faster speeds, higher signal quality and more reliable connectivity, but how are they changing the way we think about mobile security?
As more people connect to both wired and wireless networks via smart phones, tablets and laptops, security will continue to be a top concern. New Wi-Fi models, such as Beamforming and Wi-Fi Direct, are helping drive mobile devices to the faster, more secure 5GHz band, therefore offering secure ways to enable the Internet of Everything to connect more people, processes, data and things.
As mobility trends drive new expectations from networks, a strategic and architectural approach to secure mobility is essential, and next-generation Wi-Fi makes this possible.
