CMX Analytics at Cisco Live! San Francisco 2014

Cisco Live! San Francisco was the biggest Cisco Live! yet—25,000 attendees. Read Chris’s blog for more on the network at Cisco Live! You also heard about the Mobility Services APIs enabling location-based services and location-enabled application development in Neha’s blog yesterday. The event also marked a milestone for our CMX team: successful location tracking of all 30,000 devices in the conference center with a single pair of MSEs (Mobility Services Engine) running on 7.6MR2 code to generate analytics and reports based on device location!

Let’s take a closer look at location analytics generated at Cisco Live! If you haven’t seen CMX Analytics before, let me tell you: it’s powerful. There are three pieces of CMX Analytics: Dashboard, Analytics and Reports, all generated by the location data from the MSE. Here are a few key views from the show floor:

1.      Dashboard: The CMX Dashboard features a number of customizable widgets that visualize location data such as dwell time and device count by zone or by time.

Hourly Visitors for South Halls on Tuesday May 20

Tuesday marked a steady flow through the day with the World of Solutions and breakout sessions all day. You see that spike at 5pm? That’s when the beverages and refreshments came out—and then you see people tapering off round 7pm to head out for dinner.

In Case of Emergency, Location Accuracy Matters

emergencyGoing to NENA next week? Join us in Booth 515.

The ability to summon emergency assistance by using a phone to call 9-1-1 has been ingrained in our society for more than 40 years.  For a successful emergency response, it is critical that the responders receive accurate location information.  Traditional wired-line telephony is able to use the location of the physical wires as a source of information for caller location, whereas wireless technologies require more exotic mechanisms to locate a 9-1-1 caller.

Current trends expose risks in the emergency response system as we know it:

  • More and more 9-1-1 calls being made with mobile devices that are not mapped to a physical phone tied to a physical location in a venue.
  • Limited GPS location capability indoors can make it difficult to pinpoint the exact location of a 9-1-1 caller in a multistory building.

Accurate caller location within a building is vital for a timely response to an emergency. With more people using cell phones while indoors, the delays that can occur when emergency responders must rely on outdoor location technologies used inside a building are becoming all too common.  This challenge can be compounded in large buildings with many floors and many rooms on each floor.

TCS and Cisco meet this challenge by using the Wi-Fi network to make emergency response faster and more efficient with:

  • Seamlessly connection of the cellular and Wi-Fi location control planes, providing results within a few meters of accuracy
  • Visibility for accurate mobile 9-1-1 caller location with wireless location mapping specific to the venue

Next week, TCS and Cisco will be presenting this innovation solution at the National Emergency Number Association conference in Nashville, Tennessee.

Come see how we’re disrupting the emergency response space at booth 515. Join us for one of our Buzz Sessions in the NENA Exhibit Hall:

  • Monday, 11:45 a.m. – 12:15 p.m.
  • Tuesday, 12:00 p.m. – 12:30 p.m.
  • Tuesday, 2:45 p.m. – 3:15 p.m.

The Network After 25 Years of Cisco Live!

#clus1A lot can change in 25 years. At the first Cisco Live (then known as Networkers conferences) in 1989, 200 geeks gathered for the inaugural event. Fast forward to three weeks ago, when we welcomed a whopping 25,000 attendees into the arms of our namesake, beautiful San Francisco.

We heard there was some interest in how the network performed at the show, so I wanted to share some of the interesting statistics about the network at Cisco Live! I shudder at the thought of the ancient network from 25 years ago. So here we go:

Wi-Fi Client Devices

This year we saw 30,705 unique devices, with 7000 in the theater for John Chambers’ keynote.

# of Unique Clients

# of Sessions

# of Unique Users

# of Unique APs

Avg Users per AP






Max. Concurrent Connected Wi-Fi Devices

There was a peak of 14216 concurrently connected device at SF this year.

How Does a Cisco Aironet AP2700 Perform Under Stress?

There’s been some speculation about the performance of the AP2700--just how good could our latest AP fly under stress? We were talking with Blake Krone and Sam Clements from the No Strings Attached Show, where they produce independent discussion and commentary on a variety of wireless equipment and technology across vendors. The idea came up that they could do an independent performance test on the Cisco Aironet AP2700. The guys received no compensation for the testing with the exception of arranging their travel out to Richfield, OH facility for the testing. We also provided 2 AP’s per person just in case they wanted to do some further testing.  

Sam & Blake along with several Cisco TMEs loaded up an AP2700 with 100 real clients to see what happens.   The testing was meant to be as real world as possible, so they did things like setup the clients at varying distances and angles, use a mix of 11n and 11ac clients, tested with CCO code (7.6MR2), and even factory reset and configured the controller then in front of Blake and Sam to show there’s no funny business.  The idea being, if you had 100 clients, and wanted to do the testing yourself and repeat the results, you could. I don’t want to spoil the results, so head to to check out the whitepaper. 

Here’s a sneak peek at the client setup:

Wi-Fi Roaming 101

Wi-Fi roaming is often a tumultuous subject.  The crux of the issue is, with Wi-Fi the roaming decision is left to the client.

In the recent years, there have been great strides in improving Wi-Fi roaming with the creation of standards-based roaming technologies.  Cisco first pioneered fast roaming many years ago with CCKM (Cisco Centralized Key Management), which was the foundation for 802.11r.  11r which was ratified by the IEEE in 2008, allows for fast roaming, even on a secure 802.1X SSID.  With 802.11r it is possible to roam without disruption during a voice or video call.

While client support of 802.11r is largely lacking in the laptop space,  there is large support in the smartphone realm.  Apple iOS devices have supported 11r since iOS 6 (  The recent Samsung smartphones, such as the Galaxy S4, S5, and Note 3, also support 11r.

Note: Some non-802.11r clients can react adversely when connected to an 11r WLAN.  The current recommendation from Cisco is to have a separate WLAN for 802.11r clients.

802.11k is another amendment from the IEEE that helps to improve roaming.  802.11k provides a whole slew of information to the client, which allows the client to understand the RF environment and make an informed roaming decision.  This information can include channel load and AP neighbor lists.

11r and 11k help, however, that does not mean the infrastructure is irrelevant in the roaming picture.  With the help of a model train, we did some testing to figure out just how much impact the infrastructure could have.  We compared Cisco to one of our competitors, whom we will call Vendor A.

This video summarizes the results and shows the train in action, or continue reading for more details:
