“The Internet of Things is More Than Just “Things” – Five Technology Pillars to Pay Attention To

It has been 15 years since Kevin Ashton popularized the term the Internet of Things. How could we have known then what that would come to mean and the huge impact that it would have on our lives? Cisco projects that 50 Billion things (or devices) will be connected to the Internet by 2020; or, the equivalent of 6 devices for every person on the planet. This exponential growth of connected devices is fundamentally impacting both society and the economy—changing our lives forever.

IoT 10.15

However, with all of our focus and media attention on the Internet of Things, we are really missing the fundamental technology revolutions that are reshaping our world. Radical advances in processing, storage, wireless technologies and new ways of delivering technology are reshaping our world -- all at a much faster speed and drastically reduced price.

In my view, the Internet of Things is really a short-hand for the five technology pillars that are shaping a revolutionary new, connected world. Read More »

The Key to Success in Tracking Mobile Devices: Symbiosis, Not Espionage

As a shopper enters a store, the retailer uses Wi-Fi to track her movements, interests, and shopping habits, providing a treasure trove of insight valuable to merchandising and product development alike.

And as advances in Wi-Fi promise increasing location precision and beacons promise pinpoint location based services, the future appears to be smooth sailing, right?

Well, not exactly.

Tracking the position of mobile devices accurately and correlating to personal data has been one of the most sought after Big Data objectives. And not just for retailers — the potential wealth of business value from data has drawn piqued interest across nearly all industries.

Yet in the real world, issues arise from both technology challenges and privacy concerns alike.

Technology challenges include:

  • Typical Wi-Fi accuracies in the 7-to-10 meter range (though Angle of Arrival and improved location analytics promise dramatic improvements)
  • Infrequent mobile device probing to conserve battery power
  • Interference from metal shelves & fixtures, water in products (and people!)

Privacy qualms speak to the heart of transformation in the Internet of Everything (IoE) age. IoE, after all, is the explosion of network connections among people, process, data, and things — and promises to be one of the most impactful periods of change in our history. And the people element is in some ways the whole point — to make our lives better, healthier, more efficient, and so forth. But the people issues will be just as challenging as those that arise around technology. Read More »

TU Darmstadt Rolls Out Cisco Unified Access to Prepare for 802.11ac

May 27, 2014 at 11:31 am PST

Technische Universität Darmstadt, usually known as TU Darmstadt is a research university based in Germany. It was founded in 1877 and over the last 137 years has grown to be among the largest and most prestigious public universities in Germany serving over 25,000 students per year. It is the alma-mater to many world-wide leaders from Nobel prize winners, a CEO of a fortune 500 company, a president of a country and multiple World Robocup champions.


No wonder, they have a reference from Albert Einstein!


In 2009 TU Darmstadt embraced BYOD with the 5508 Series Controller managing the 1140 802.11n Access Points. Recently we talked to Thomas Vogel, the Head of Network Group and Andreas Liebe, the Network Services Manager who have over 15 years of experience managing WLAN environments. In this blog, we will describe some of the details of WLAN deployments using the 3850 Series Switch and the 5760 Series Wireless LAN Controller to address the new requirements in the school environment.

Small Cells Are Big For Business

Closing the big deal.  Calming an irate customer.  Clarifying instructions given in an email.  Voice has long been the killer app for business.  As the world goes mobile, smartphones are becoming a key way for business people to stay connected, not just when they are out of the office, but an important means of voice communication in the office.  Like consumers, many business users are cutting the cord and using their mobile device, instead of their desk phone, to make and receive voice calls.  A recent Cisco study of mobile users reveals that 50 percent of knowledge workers use their mobile phone at least one-quarter of the time to make calls in the office, instead of reaching for a desk phone.  And, 35 percent of knowledge workers equally choose between a mobile and desk device when placing a call.  We expect this mobile displacement of the traditional desk phone to grow as employees increasingly bring their own mobile devices to work and use them for conducting business.

Mobile cellular networks were built to cover large outdoor and semi-outdoor areas.  They were never built to penetrate the steel, glass and concrete of modern buildings.  While there may be some coverage near the windows, the signal strength rapidly degrades as you head towards the center of the building.  This is only going to get worse as new building materials, such as blast resistant glass, make it even harder for signals from the macrocell network to adequately cover the place of work.  Our research found that one-third of all business users receive only 1 to 3 bars of signal strength at their place of work.  And, 10 percent of business people obtain very poor quality mobile service (1 to 2 bars).

The shift to mobile in the workplace should be Read More »

Five Predictions for the Future of Wi-Fi and Mobile

New devices, changes in customer behaviors, and technological advances are rapidly changing the mobile market and consumers’ expectations of mobility.  A recent Cisco study of mobile consumers reveals how much, and how quickly the world of mobility is changing.  The survey uncovers some startling revelations about what consumers are doing on their mobile devices, how and where they are using them, and how they are connecting them to the Internet.  Highlights of the research are revealed in my recent blog Discover What Consumers Want from Wi-Fi and Mobile.

The majority of devices are now Wi-Fi-enabled, and the fastest-growing category is “nomadic” devices like tablets and eReaders.  We now need to speak of the “mobile home,” as the home is by far the most popular location for consumers to use their mobile devices. Surprisingly, Wi-Fi is the network connection of choice for most consumers for all of their devices.  Public Wi-Fi is now a big part of mobile life.

Consumers are generally satisfied with their public Wi-Fi experience, but they want it to be faster, more secure, better quality, and most of all, available in more places. Consumers are anxious for enhanced personal mobile experiences that can be delivered by unlocking the inherent business value hidden in the Wi-Fi infrastructure.

While it is never easy to foresee the future, we are making five predictions for key changes in the mobile industry over the next two years based on insights from the Cisco mobile consumer research: Read More »
