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 »

A Balanced Approach to Mobile Security

Gartner recently made three interesting predictions about mobility in the workplace. While the ideas are compelling, they only offer one-side of the story, and the solution.

In this blog post, I’ll take a deeper look at each of these predictions and discuss why the future of mobility rests on IT leaders taking a balanced and strategic approach to security that focuses more on protecting the network and proprietary data and less on implementing overly broad restrictions.

Gartner Prediction #1: Twenty percent of BYOD projects will fail by 2016 due to IT’s “heavy hand.”

While the actual failure rate may be less than one-fifth, mobility efforts will fail if companies are too restrictive with MDM policies. Instead, a two-fold approach to supporting a BYOD environment from a security perspective is essential.

First, IT leaders should take a balanced approach to security that protects business-imperative network solutions and data. In most cases, blocking Angry Birds and Candy Crush is unnecessary and not scalable. With Apple and Google supporting over a million apps each (and counting), it can cost precious time and IT resources just trying to keep up with restricting non-threatening applications.

Secondly, IT leaders should be focused on encouraging users to use secure solutions. This will only grow more important as the explosion of new connections and various devices evident in today’s Internet of Everything world creates more opportunity for malicious actors to utilize even more inroads to compromise users, networks, and data. By educating employees to take an active role in the security of their device, users can be empowered to report suspicious threats and have an open dialogue with IT teams. 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 »

Curious About Cisco and Facebook’s Partnership for Wi-Fi?

More and more organizations across industries are realizing that providing simple, easy Wi-Fi for customers, guests, visitors, and more is becoming a basic expectation. Consumers are used to their always-on, always-connected lifestyles, so naturally their checklist for any venue they step into will now include “Wi-Fi” as a top priority. Good thing Cisco has not one but two simple ways for organizations with venues to provide easy Wi-Fi access for their consumers. One is CMX Connect, which you read about in the MSE blog series. The other is CMX for Facebook Wi-Fi.

We announced our partnership with Facebook last October to help connect businesses with their consumers at Interop New York. This Wednesday, January 22nd, we are having a special live webinar to give our customers a deeper dive into the Cisco and Facebook Wi-Fi solution.   Register to join us at 10am PST!

Don’t miss this opportunity to hear from Cisco and Facebook speakers, as well as a special guest customer, to learn more about our joint-solution. Hear how CMX for Facebook Wi-Fi can help boost recognition for your brand, foster stronger relationships with customers, and promote your business by connecting you directly to customers through Facebook.

Are Small Cells and Wi-Fi Networks Complimentary or Competitive?

As an industry, we are starting to see a convergence of small cells and Wi-Fi to help solve coverage, capacity, and spectrum issues in our increasingly connected, mobile-dominated world. Today more than ever, mobile operators are increasingly realizing that Wi-Fi and small cells must be part of their traditional licensed network in order to realize the future of mobility.

This topic was especially evident during last month’s Small Cell Americas conference in Dallas, Texas. During the conference, I had the opportunity to discuss how small cells and Wi-Fi can work together, which proved especially timely as the Dallas conference also marked the launch by the Small Cell Forum of their Enterprise Release, comprising  of 25 documents to help overcome barriers to small cell deployment in the enterprise. Release Two: Enterprise is the result of over nine months of hard work by the Forum and its members!

As small cells and Wi-Fi bring corporate networks and mobile networks closer to each other, IT leaders and service providers are increasingly asking questions about how the convergence of small cells and Wi-Fi coexist, from a product, architecture and business model perspective. Some common questions include: Read More »
