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 »

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?

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 »

Deloitte’s 2013 Annual Holiday survey came out with some staggering statistics:
- Nearly 7 in 10 shoppers will use their smartphones and tablets to shop this holiday season.
- Nearly half of all shoppers will use social media to assist in shopping.
- 73% of shoppers will be influenced by coupons and promotional offers.
Retailers both online and in-store can no longer ignore the power of mobile technology and social media influence with shoppers. Shoppers using mobile devices inside stores are actually more likely to make a purchase when being presented with the right information. In fact, this isn’t only true for retailers, but across all industries. Whether it’s guests, visitors, patients or passengers, there’s a real opportunity for businesses to make an impression via the mobile device.
Today I am happy to announce our latest Cisco Wireless Software Release 7.6. As you may recall from Sujai Hajela’s State of Cisco WLAN blog earlier this week, Cisco’s Wireless group has been ahead of the competition with our dedication to delivering cutting edge, high performing technology to our customers.
Many features in Release 7.6 were designed specifically to enable our customers to take advantage of the latest mobile trends. Here are some of the highlights:

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.
