The previous blog on CleanAir went in depth on how MSE uses CleanAir information to locate interferers and the impact zone for each interferer. This blog takes a step back and gives an overview of the CleanAir technology.
How Interference Affects Your WiFi
802.11 devices operate in the 2.4GHz and 5GHz unlicensed bands. These are unregulated and experimental bands. As such, there are way more non-802.11 devices, including but not limited to cordless phones, video cameras, microwave ovens, Bluetooth headsets, DECT phones and even X-Boxes. Now even more devices are coming out that emit in these bands. These devices interfere with your WiFi network since they don’t work cooperatively with 802.11 devices, causing reduced network capacity and coverage, poor quality of voice and video, and link failures.
When an 802.11 device is ready to transmit and it senses interference, it will hold off transmission until it is finished. If it is in the middle of a transmission where it has sent a packet and never receives an acknowledgement, then it will try to send the packet again. Issues like these impact the throughput and capacity of your Wireless Network. An interferer like a microwave oven, which emits interference on a 50% Duty Cycle, will reduce the throughput by 50 percent. In the case of an interferer like a video camera, which emits interference at 100% Duty Cycle, when seen at Access Point above CCA threshold will stop the Access Point from beaconing. Due to this clients will not attempt to associate. Read More »

Released along with the Wireless Release 7.5 earlier this month was the latest version of Connected Mobile Experiences (CMX), continuing Cisco’s leadership in the emerging field of WiFi location based services and analytics. Release 7.5 delivers a rich set of innovations to enhance the existing Connected Mobile Experiences (CMX) solution.
This is a very exciting new release delivering many new features and functionality to the solution. Here is a brief summary of the highlights from the release:
Version 7.5 continues ongoing improvements to the existing analytics capabilities such as improved usability, enahnced ‘look and feel’, as well as easier to generate analytics results and increased support for complex building layouts. In addition, the user interface and the appearance of the 3D interface has improved to display clearer information enabling a better understanding of the visitors to the venue.

Editor’s Note: This blog post was co-written by Dr. Brendan O’Brien, who is authoring the post, and Dr. James Little, technical lead for CMX Analytics in Cisco’s Wireless Networking Group.
This year’s CiscoLive! in Orlando with over 20000 visitors was selected as an ideal opportunity to test and prove CMX Analytics over a large venue with high volume usage.
This year’s CiscoLive! was spread over two huge venues of the Orange County Convention Centre and the Peabody Hotel between June 23rd-27th. Over two and a half days, approximately 40,000 different devices were detected using CMX Analytics. (This figure is not uncommon any longer, assuming 50% of people had WiFi on and most of us had 2 or more devices)
The main purpose of the Wi-Fi network at CiscoLive! is to provide a high quality service to all attendees, providing CMX Analytics with its toughest test yet. With a peak of around 15,000 connected devices on the opening day serviced by 750 access points and 1500 radios, the challenge was to see how well CMX could take the raw numbers and translate it into insights on the movements of the delegates.
Let me break down some of the reports for you:
In the table above, CMX Analytics shows:
- The second floor being busier than the 1st, 3rd or 4th during lunchtime. as expected with the catering facilities located there.
- The World of Solutions was also busy over this period as it was a break between sessions.
- The keynote areas are expectedly quiet during this time. Read More »

Location Based Services in the Service Provider (SP) world is a very hot topic at present, with many SP’s looking for monetization opportunities for Wi-Fi.
Cisco has been working with our service provider customers to help deliver monetization capabilities; one way of opening new revenue opportunities is by using our new Connected Mobile Experiences (CMX) Solution.
Dr. Brendan O’Brien, Director of Product Marketing for Cisco Connected Mobile Experiences, continues his thought leadership blog series to tackle the trend towards location-based services in the Service Provider space. Brendan takes a brief look at some of the drivers for Wi-Fi in the SP world and some steps along the value chain, then dives into the emerging models where SP’s are beginning to focus their attentions on monetization and new, additional revenue opportunities.
