Advanced Use of CMX at the Internet of Things World Forum in Barcelona

The inaugural IoT World Forum closed today in Barcelona with the overall sentiment being that it was a resounding success.

One of the key messages that emerged was the need for everyone to work together and for the customer solutions of the future to be drive by business outcomes or capabilities, rather than by what it takes to deliver them or the underlying components or technologies. Increasingly business leaders are making their purchasing decisions by prioritizing business value and business relevance.

Cisco’s Connected Mobile Experiences was highlighted at the World Forum and is seen as one of the key pieces of the overall IoT jigsaw.

Some very interesting use cases for CMX and its capabilities were showcased this week. In a previous post I spoke about the Smart City Tour and how CMX is used in an innovative manner within the city and how brands can take advantage of CMX to engage their customers in creative ways. In another post I spoke about how CMX was used within the IoT venue and the analytics that were available for all to see on the event jumbotron.

There are a few more (yes, even more--with CMX, the possibilities of deployment are endless) ways that we wove CMX into the IoT experience that’d I’d like to share with you in my final IoT World Forum string of posts.

One of these was using CMX within the City of Barcelona as a key dashboard of information for the municipal authorities. Here is a view of the Born area part of the old Gothic section of the city and a major tourist destination in the city. We can see here that over 6600 devices where detected with an average dwell time of 8 minutes.

Interference Detection and Mitigation with Cisco CleanAir

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 »

Cisco CMX Solution – Version 7.5 Released

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:

CMX Analytics:

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.

Cisco CMX Analytics in use at CiscoLive! Orlando

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 »
