Cisco Systems is announcing a new set of features that enhance its HDX (High Density Experience) suite. This blog is the third in a series that explains the new features that comprise the enhancements to HDX.
The first blog in the Enhancing HDX series is here. The second blog in the Enhancing HDX series is here.
What is 802.11v? What is BSS Transition Management? Why are these Important?
In this blog, two different series are intersecting: Enhancing HDX and the series looking at the lesser known but undeservedly underappreciated amendments to 802.11 and the features/benefits they provide.
Previous blogs briefly explained the basics of 802.11k “WLAN Radio Measurements” and specifically zoomed in on the Neighbor Request/Report and also explained the basics of 802.11r “Fast BSS Transition”
This blog will briefly explain the basics of 802.11v “Wireless Network Management” and will also explain how 802.11k Neighbor Request/Report and 802.11r “Fast BSS Transition” can provide a “better together” solution with 802.11v. It also explains where it fits in with High Density Experience (HDX).
Wireless Network Management (802.11v)
Wireless network management (WNM) enables devices comprising the WLAN to exchange information with the goal of improving the quality of experience when using the WLAN. Network administrators benefit from using WNM by having additional ability to fine tune the WLAN in order to provide improved reliability of services to their end users and the end users benefit in turn from using a WLAN that has been designed to provide more than mere connectivity.
Client devices and infrastructure may both use WNM to exchange operational information so that both clients and infrastructure have additional awareness of the WLAN conditions. That awareness can help provide a firm foundation for self-correcting events and actions to be implemented. In other words, WNM isn’t about being a “control freak”; it’s about raising the bar in the Wi-Fi ecosystem so as to create better Wi-Fi networks.
But not only does WNM provide information on the state of network conditions, it also provides a means to exchange location information, supports efficient delivery of multicast (group addressed) frames, and enables a power savings mode in which a client can sleep for longer periods of time without receiving frames or being disassociated from the AP.
Given this, it can be easily appreciated why WNM has often been described as a “kitchen sink” of features. This blog won’t take the time to go through each and every feature introduced in the 802.11v amendment. But in order to emphasize the potential richness of the feature set, the following is an alphabetized list:
The remainder of this blog is going to focus on BSS Transition Management. Future blogs will cover other aspects of 802.11v.

If you are a professional photographer or even an amateur like me, you want to have ready access to various control dials on your camera to capture the moment perfectly. Professional cameras provide high level of control to get the best outcome. But there are times when you want to put the camera and the lens in Auto mode or wish that the camera could automate some decisions that make your workflow easier.
Likewise, Cisco Wireless LAN products provides the level of quality, functionality and control that is unmatched and hands-down the best enterprise wireless networking portfolio in the industry. But there are scenarios where it is preferable to expedite wireless configuration with best practices automatically enabled and easy access to data to simplify monitoring and troubleshooting workflow. For example, a small business owner manages his own network or in a K-12 a librarian acting like a part-time IT administrator. This not only provides operational efficiencies for the IT organization but also improves end-user and partner experience.
Cisco WLAN Express Setup is an attempt in this direction. It is now available on 2500 Series Controller (CT2504) starting with software release 18.104.22.168.
It includes three components
- Easy-to-use setup wizard: This eliminates the need for console cable and command line setup. Instead, 3-step web-wizard is used to quickly boot strap a Controller and configure employee and Guest WLAN out of the box.

Cisco Wireless Release 8.0 is now available: Product Bulletin
The Cisco VNI Global Mobile Data Traffic Forecast, 2013 – 2018 revealed some stunning trends with growth projections that are sure to have a dramatic impact on wireless networks worldwide.
In 2013, globally, there were nearly 22 million wearable devices generating 1.7 petabytes of monthly traffic. There were about 7 billion mobile-ready devices and connections with mobile network connection speeds that have more than doubled, to 1.4Mbps up from 526 Kbps in 2012.
By 2018, there will be more than 10 billion mobile-ready devices and connections. The average mobile connection speed will nearly double, from 1.4 Mbps in 2013 to 2.5 Mbps and over 4.9 billion devices will be IPv6-capable. There will be more traffic offloaded from cellular networks (on to Wi-Fi) than remain on cellular networks.
