Not All 802.11ac AP’s are Created Equal: Demand the Full Story

It’s always interesting and often entertaining to observe how competitors promote their products and what they choose to focus on—and more importantly, what they choose not to focus on and what they hope people won’t ask questions about.

Consider yet again how a competitor chooses to position their “purpose built” AP vs. the Cisco Aironet 3700 802.11ac Access Point Series.

This competitor frequently (and somewhat obsessively) points out that its 802.11ac AP has dual “active” 800 MHz cores while the Cisco AP3700 has only one “active” 800 MHz core. This is not completely true since it completely overlooks the fact that the Cisco AP3700 also has a dedicated CPU core and DSP for each radio subsystem.

Furthermore, it also overlooks that the dual “active” cores in the competitor’s AP share 512 MB of DRAM. The single “active” core of the AP3700 has dedicated 512 MB of DRAM. Also each radio subsystem has a dedicated 128 MB DRAM (for 768 MB total DRAM in the AP3700).

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  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 »

Detecting Payment Card Data Breaches Today to Avoid Becoming Tomorrow’s Headline

TRACA few months ago we discussed the various ways that consumer PII is compromised. The recent attacks against Target and Neiman Marcus illustrate the constant threat that payment card accepting retailers of all sizes face. Yesterday Reuters reported that similar breaches over the holidays affected “at least three other well-known U.S. retailers”. Given the current onslaught, it’s a good time for retailers to examine their detection capabilities before a payment card data attack, while creating new goals for shortening remediation windows during and after an attack.

Integrated Collaboration Highlights and Updates from InfoComm 2013

What a great reception at InfoComm 2013! We had the opportunity to share with customers the innovations we are driving around conferencing to deliver better scale, quality and interoperability.  They are excited about what we are doing to make conferencing more affordable, while at the same time maintaining the high quality experience that they expect from Cisco.

It was fantastic to see such a high level of interest in our new pervasive conferencing announcements.  Here are a few highlights of what we demonstrated at the show:

  • Further increases in scale, enabling greater efficiencies and affordability – we now support up to 96 video systems in a single meeting and virtually unlimited participants through WebEx enabled TelePresence.
  • Simplified solution choice with a broader range of deployment options – now included is  virtualized software, and the new compact Multiparty 310 and Multiparty 320 appliance platforms.
  • Entry level packages for new customers – customers can now deploy a compact appliance solution, and start from one screen license.
  • Increased interoperability – we now provide support for interworking with H.264 SVC clients. Read More »

When Is “Good Enough” Video…Well, Good Enough?

There’s no doubt that video is becoming more pervasive in business.  It’s no wonder: humans are visually oriented. We’ve been reading people’s faces since we were newborns, so it’s natural for us to use visual cues as we build stronger relationships and better organizations.


As video makes deeper inroads in enterprises large and small, I keep hearing the concept of “good enough” video. So what does “good enough” really mean? Is there a specific number of pixels, or frame rates, or a certain standard that makes video “good enough”? How can you define “good enough” for your organization?

If you focus on the results your organization wants to achieve, your video collaboration strategy will fall into place.

Here are the most important things to help you define a video collaboration strategy that is “good enough” for your organization’s goals.
