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 »

One of the most consistent challenges in designing for your customers’ digital experiences is understanding what things they’ll be doing when, which in turn governs what device they’ll be doing those things on. Will it be on the couch with a tablet? On the go with a smart phone? At work on a laptop?
On the Cisco digital team, we do a lot of research and planning on this very topic, and have found that some tasks are very time/device specific (such as looking up appointment information or background information on your phone right before a meeting) while some are more broad and could happen anywhere, such as checking product information or searching. To illustrate this better to our teams internally, we put together a storyboard to illustrate how our customers and partners use multiple devices (desktops, laptops, tablets, smart phones) within the course of their day when interacting with us and each other. Here’s a panel from it:
What this doesn’t show is that there are also “could happen anywhere” cases. These are often the most mundane of things, but important ones. For instance, our login page on Cisco.com receives more than 2,000,000 visits per month. But when we took a look at the mobile part of the login experience, we knew something had to be done!
The most obvious problem with this page above is the teeny tiny type. And then, to use it, you have to stretch and zoom to get the fields big enough to even type into. It was, as we euphemistically say in the tech biz, “suboptimal.”
One solution would have been to create separate login designs for large tablets, small tablets, phones and desktops. Instead, we chose a smarter way, using Responsive Design, which I have blogged about previously: We used one “smart” code base that adapted the display for the size of the current device. The result was very simple and very nice: A clean login page we launched recently that retains its normal behavior on the desktop browser, but shrinks to fit for tablets and smart phones. It’s a simple example of where Responsive Design saves time in deployment because we could write the code once and put it through one development and test cycle, rather than creating three or four different experiences and having to develop and test them all separately.
Responsive design doesn’t solve every problem — and there are many, many experiences on mobile that need to be designed specifically for venue and device. But use responsive design where it helps save time and money, and can provide some consistency in basic behavior.
Thanks to our mobile, design, and IT teams for pushing this out. Enjoy!

They may seem simple changes, but we think some recent updates to the Products & Services page on Cisco.com will make this page easier and quicker for you to use.
Here are some of the main things we’ve improved:
- Links are more obvious. Previously, some links were hidden behind drawers. Examining the metrics — plus testing with you — convinced us to make all the links visible, which will definitely help for findability.
- Scanning the list of products is easier.
- Scanning the list of services is easier and the lists are more obvious.
- There’s a new “Key Topics” module which allows a clear navigation path to these important areas.
- Borderless Networks; Collaboration; and Data Center & Virtualization are highlighted.
- We’ve updated the “Let us Help” content to reflect all of our main contact methods so you can connect with us more easily.
- It’s easier find key links to areas like Visio stencils and EOL products. And, we’ve added a few new links places like the Developer Network Marketplace and Developer Network (Resources).
A lesson is this update is that sometimes, simpler is better. The previous design was an improvement over its earlier version, but also had some interactive elements such as switchable tabs and popup drawers; these may have been “cool” to play with, but didn’t do much to help usability or speed of navigating on the page. We’ll let you know how this new, more simple version performs.
The new page:
For comparison, the previous version:
The older one is shorter, but in the end, we find that people don’t mind scrolling or swiping a bit to get to the information they need. It’s much better to have the information visible.

Here’s something I think you’ll like: Rich information about the entire Cisco product and services portfolio is now available free in a smartphone-friendly format.
This update includes:
- More than 7,000 product series and model pages for mobile access
- Complete coverage for Services products
- More than 1,180 product oriented videos now playable on mobile devices for the iPhone and Android platforms. (We’ve converted 31 GB worth of videos!)
- Links to data sheets and other key information that you can browse to quickly, in both HTML and PDF format.
You can access it from your mobile smartphone start at m.cisco.com. We’re treating this like a “Beta” — primarily because we are still working on table treatments — and tuning every day. But I know you’ll find a lot to like here when you’re on the go.

I used to be the sort of fellow who eschewed design or leadership awards for web sites. I figured the true measure of success is seeing the sites used every day for Customers and Partners answering their questions, assessing the right product fits, communicating with their colleagues on forums.
I still take awards with a grain of salt, but we’ve gotten several mentions lately for Cisco.com, so I thought it would be worth a brief recap for the following reason: These awards not only reflect our team’s hard work here at Cisco, but also your participation. They show:
- How you’ve helped us achieve excellence (or strive for it, at least) with your regular participation in comments to the site and in our 1:1 usability tests that we do around the globe via WebEx.
- How our team has worked diligently to continuously improve our web, social and mobile experiences, based on your input.
Here is a list of some of the accolades we’ve gotten lately, and then I promise I’ll stop bragging for a while:
- As Bill Skeet just blogged recently, our Online Support experience recently won the “Ten Best Support Sites” award from the Association of Support Professionals (ASP). And, Cisco was awarded the 2012 Technology Services Industry Association (TSIA) STAR Award for “Best Online Support” for the fourth year in a row.
- Cisco recently won an Award of Distinction for our Brand Identity System, which includes the web site. The scope of this one included Cisco brand guidelines, along with brand assets such as Cisco.com, navigation, photography, icons, templates and more.
- Cisco.com is a 2012 Webby Honoree: Official Honoree distinction is awarded to the top 15% of all work entered 10,000 entries received from the US and more than 60 countries.
- And, our Cisco London 2012 website has also been selected as an Official Honoree of the 16th Annual Webby Awards in the Corporate Communications category.
- Cisco won a bronze ADDY in the AAF-Silicon Valley ADDY Competition. This award is for our new Brand Identity System which includes all of the standards for the web, mobile and social venues. The ADDYs are arguably the world’s largest creative competition, with over 60,000 entries each year nationwide.
- Cisco’s Connected Life Exchange blog was honored at @btobmagazine Social Media Marketing Awards. In the article, the writer says “The whole package is refreshingly non-promotional and often fascinating. Cisco continues to innovate in the suddenly red-hot field of content marketing with an approach to thought leadership that emphasizes actual thinking.”
And, I already mentioned these, but they bear repeating because these focus on coverage and usability:
Our digital teams don’t think about awards that much; but we do think about you and how you use our web sites, mobile and other digital experiences every day. And I like to think that focus has translated into some of the recent accolades.
