HDX Blog Series #4: Optimized Roaming

Editor’s Note: This is the last 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.

If you’ve been a long time user of Wi-Fi, at some point you have either observed someone encounter (or have personally suffered from) so called “sticky client syndrome”. In this circumstance, a client device tenaciously, doggedly, persistently, and stubbornly stays connected to an AP that it connected to earlier even though the client has physically moved closer to another AP.

Surprisingly, the reason for this is not entirely…errr…ummm…unreasonable. After all, if you are at home, you don’t want to be accidentally connecting to your neighbor’s AP just because the Wi-Fi device you’re using happens to be closer to your neighbor’s AP than to your own.

However, this behavior is completely unacceptable in an enterprise or public Wi-Fi environment where multiple APs are used in support of a wireless LAN and where portability, nomadicity, or mobility is the norm. In this case, the client should typically be regularly attempting to seek the best possible Wi-Fi connection.

Some may argue that regularly scanning for a better Wi-Fi connection unnecessarily consumes battery life for the client device and will interrupt ongoing connectivity. Therefore the “cure is worse than the disease”. But this is true only if the client is very aggressively scanning and actually creates the complete opposite of being “sticky”.

The fundamental issue with “stickiness” is that many client devices simply wait too long to initiate scanning and therefore seeking a better connection. These devices simply insist on maintaining an existing Wi-Fi connection even though that connection may be virtually unusable for anything but the most basic functionality. Read More »

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 »

Thinking Outside of the Building

You’ve all heard the saying “think outside the box” when encouraging someone to be creative and come up with new ideas, new ways to do things, new ways to…..just about anything.  Well, I’d like to take a small twist on the well-known saying and talk for a moment on how deploying outdoor Wi-Fi access points should be something you should be “thinking” about.

We all know that here in late 2013 almost everywhere you go, you can pull out your laptop, tablet, or smartphone and you will find Wi-Fi coverage, be it at your workplace, at a coffee shop, or in a retail store.  Why is Wi-Fi coverage so pervasive in these areas?  Because connecting to Wi-Fi access points and the data network behind them makes employees more productive, enables the coffee shop to be the new remote office (while selling more coffee and cakes), and provides the retail store the ability to gather analytics to better target offers for their customers.

Now let’s think about expanding this coverage to outdoors….outside the buildings.  The same holds true.  Providing Wi-Fi access in the surrounding outdoor locations frees up employees to take their laptops outside and enjoy a nice, sunny day while still being “online” for secure corporate email and business tools.  It allows the employee to connect to that important WebEx meeting he is running late for as he pulls into the parking lot. It allows the retail store to engage with customers thru Cisco’s Connected Mobile Experiences (CMX) earlier and push offers to them as they walk in from the parking lot, perhaps pulling customers headed to nearby stores who might otherwise not have stopped in.

A Powerful Network Simplifies Adoption of New Mobile Devices

It’s a critical time for enterprise IT as new mobile devices from Apple, Samsung and Google enter the market and operating systems are updated almost weekly. Apart from the new color and form factor options, this round of new technology features new operating systems and a proliferation of app updates, which IT leaders must be prepared to meet head on.

It’s an exciting time for mobile technology, but it’s also an important time for enterprises to look at not only meet the demands of today’s mobile-enabled workforce, but tomorrow’s as well. Basic mobility functionality is not and will not be enough, and a solid framework must be put in place to support the growth.

In this inaugural post of a four-part Network Matters blog series, I’ll be discussing how IT leaders can rely on a network, built for all kinds of devices, to simplify the process of onboarding new mobile technology and free up precious IT resources. I would like to provide you with a deeper look at how having the right network in place can help ease the challenges of tomorrow that will be presented to IT departments due to device evolution and enable a culture of self-service for employee-owned devices.

Cisco Leads the Gartner Wired and Wireless LAN Infrastructure Magic Quadrant Again!

Gartner has released their 2013 Wired and Wireless LAN Infrastructure Magic Quadrant.  For the 2nd time in a row, Cisco is recognized as a leader in this highly anticipated publication.

Here is the 2013 Gartner Magic Quadrant for the Wired and Wireless LAN Access Infrastructure (Authors: Tim Zimmerman and Mark Fabbi; Published 3rd September 2013).

This graphic was published by Gartner, Inc. as part of a larger research document and should be evaluated in the context of the entire document.

There are two primary criteria for the Gartner MQ — (a) the Completeness of Vision (b) Ability to Execute.

From a vision perspective, Cisco unveiled its vision of Unified Access – One Policy, One Management, One Network — more than a year back (last June, to be precise). This vision was the first step in helping our customers drive business innovations and achieving IT simplicity while addressing the rapid growth of BYOD and Mobility in their organizations.

We were also ahead of the times by having a vision for the network to be a strategic asset (and not a cost center) for our customers. And the way to make this happen was to leverage the network intelligence to drive new customer experiences and revenue opportunities. That’s where our vision of Connected Mobile Experiences (CMX) came about. The idea behind CMX was to enable organizations to improve customer loyalty and increase revenue by delivering context-aware mobile information that matches their customers’ real-time needs and preferences. A retail store, for example, can use the CMX solution to enhance mobile shopping experience, increase loyalty app usage, create targeted personalized marketing and context-rich notifications, and use on-premise visibility to understand and adapt to customer behavior. Its no surprise that the majority of our customers have jointly embraced this Cisco vision and a lot of our competitors are now trying to follow suit.

But the proof is in the pudding.. Read the full blog to find out how Cisco has executed on this vision.
