HDX Blog Series #3: 802.11ac Beamforming At Its Best: ClientLink 3.0

Editor’s Note: This is the second 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.  Read part 1 here. Read part 2 here.

The 802.11ac wireless networking standard is the most recent introduction by the IEEE (now ratified), and is rapidly becoming more accepted and reliable industry standard. The good news is that the client and vendor adoption rate for 802.11ac is growing at a much higher pace as compared to when 802.11n was introduced back in 2009. There has been an accelerated growth seen with the mobile and laptop devices entering the wireless market embedded with an 802.11ac WiFi chipset. Unlike in the past, laptop, smartphone and tablet manufacturers are now acknowledging the fact that staying up to date with the latest Wi-Fi standards is as important for the bandwidth hungry users as having a better camera or a higher resolution display.

With the launch of the new 802.11ac AP 3700, Cisco introduces the Cisco HDX (High Density Experience) Technology. Cisco HDX is a suite of solutions aimed towards augmenting the higher performance, more speed and better client connectivity that 802.11ac standard delivers today.

ClientLink 3.0 features as an integral part of Cisco HDX technology designed to resolve the complexities that comes along with the new BYOD trend driving the high proliferation of 802.11ac capable devices.

So what is ClientLink 3.0 technology and how does it work?

ClientLink 3.0 is a Cisco patented 802.11ac/n/a/g beamforming technology Read More »

HDX Blog Series #2: Scaling with Turbo Performance

Editor’s Note: This is the second 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.  Read part 1 here

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 »

Cisco CMX @ CES 2014

internationalces14This week CES was once again held in Las Vegas with in excess of 100,000 people in attendance.

Cisco demonstrated a number of CMX and IoT related things this week.

Firstly “The Internet of Everything:  On The Go”

In the Cisco booth some future thinking was applied with a concept that imagines the shopping experience with a simulated retail environment:  “BigBox.” While shopping at BigBox, visitors can walk through a combination of experiences involving location-based data, video, predictive analytics, security cameras, and sensors – designed to help retailers enrich the shopping trip for their customers, and more efficiently manage their stores.

Somewhat scary for some and exciting for others, while all the time enabling retailer increase their bottom line and deliver improved and personalized shopping experience to the consumers.

The next demo “Starlight Resort” was a combination of CMX, and Small Cell capabilities in the hotel resort environment. Read More »

Looking for Santa? Use Cisco Location-Based Wi-Fi!

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.
