With any new technology comes a new set of obstacles to overcome. 802.11ac is no exception. Last week we talked about CleanAir for 802.11ac and why spectrum intelligence still matters. Another challenge is scalability. In this post I will give you some details on new HDX feature, Turbo Performance, which allows the AP 3700 overcome common scaling issues to scale amazingly well.
What’s Different with 802.11ac?
802.11ac means higher data rates, which means more packets per second (PPS). There are three reasons for more PPS with 11ac: wider channels, increased modulation and increased aggregation. Channel width doubled to 80 MHz, modulation increased from 64 QAM to 256 QAM, and aggregation increased from 64k to 1MB!
With 802.11n, an AP might have had to push 30,000 1500 byte packets per second through the APs data plane. Today with 802.11ac that could now be 75,000+ PPS. More PPS means more load on the APs CPU, so to really keep up with the demands of 802.11ac, we needed to go back to the drawing board. Read More »

Are you at #NRF14 this week? Join us in Booth 1954 and learn about our solutions to integrate next-gen technology into retail.
Superheroes and their super strengths have long captured our imaginations. Today, such daydreams – and abilities are getting just a bit closer to reality.
When your smartphone meets the Internet of Everything (IoE), it will make some common activities, such as shopping, a bit more super. Mobility has already assumed a central role in the retail experience, but how are increased contextual capabilities emerging across the entire customer journey?
This blog discusses how some retailers are connecting people to people and people to things, while tapping superpower abilities and making their brands and product experiences distinct.
With the superpowers of smartphones and IoE, retailers can insert themselves into crucial conversations with the customer by offering price matching, access to expanded inventories, suggestions, and shopping lists. All of these combine to keep shoppers engaged and moving along the journey – and beyond.

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.
