Many network engineers recall the iOS7 update on September 18, 2013 as one of the most historic download days of their network’s history. All the more reason for us in the wireless world who anxiously anticipated the September 17 release of iOS8.
We asked a few of our customers to monitor the effect of the software release on their networks and the results for the first two days are in. Those in the education and healthcare space in particular are filled with early adopters of WiFi technology and devices, and eager to get their hands on the latest updates.
Joe Rogers, Associate Network Director at the University of South Florida shared this picture with us from 1pm September 17th, showing 1 Gbps more traffic than he would normally see at this time of day:
Another customer, Greg Sawyer, Manager of Infrastructure Services, shared this picture of the iOS8 effect on his network at the UNSW Australia.
He noted that his experience handling the release this year felt smoother than last year, despite the new peak internet download of 4.65 Gbps and 21Tb downloaded for the day! Not too surprising when considering that there were 27,000 concurrent connections on the wireless network and approximately 60% of those being Apple devices.
How should organizations be considering and handling these network spikes? I sat down with Cisco technical leaders Matt MacPherson and Chris Spain (@Spain_Chris) to get some insight on the effect of big updates like iOS8 on the wireless network. Here are some of the highlights of what we discussed:
The World We Live In
The truth is, more and more services are being moved to the cloud—a cloud that will push updates to millions & in the future billions of users and devices on our networks. Read More »

Cisco has been placing a lot of emphasis on delivering solutions that provide insights and understanding on how customers, patients, visitors and communities interact with their physical environments. Mobility and leveraging mobile devices in the environment has revealed itself as a very powerful way to gather critical business intelligence. This business intelligence is highly impacted by the resolution of the location-data and the demand to improve resolution and accuracy is increasing quickly. Apparently, this has not been missed by UBM. This year Cisco is honored to be selected as a Best of Interop Finalist for the Wireless award category for our innovations in improving location data resolution calculations.
It’s an honor to be recognized for our innovation and technological advancements in wireless, and we wanted to share a bit more about our submission with you.
What are Location Data Resolution Calculations?
Many systems acquire location analytics by relying solely on the probing that occurs from a mobile device to an access point. Unfortunately, this approach is delivering diminishing returns. It puts location analytics at the mercy of the mobile device vendors. What I mean by this is that as mobile device manufacturers look to improve mobile devices in regards to OS, drivers and battery life they are reducing the frequency of the probing from the mobile device. In addition, different mobile device manufacturer use different probing intervals. The need to do this makes sense from the mobile device manufacturer perspective, but it has an impact on the accuracy of the data acquired when representing movement of end users in the physical environment. If a user is recognized when they walk in the environment and then is identified a minute later, there is a lot of movement that can occur in that time. But the analytics only sees two data points and draws a straight line. Not a very accurate representation.
Cisco is leveraging what we know best, the network, to supplement the device probing. Bringing in network data allows us to gather higher data resolution regarding mobile device movement, equating to a more accurate representations of end user movement in the environment.
