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 »

Observations from the 2014 Consumer Electronics Show

I am just back from attending the 2014 Consumer Electronics show in Las Vegas where I was meeting with customers and visiting the massive show floor. CES is an intriguing blend of extremes and contrasts: biggest and the smallest; connected and unconnected; wired and wireless; high tech – low tech.  As personal and business technologies converge through the “consumerization of technology”, CES provides an exciting window into the current and future world of technology.

As with every show, there are things which are the same, more advanced or completely new from the previous year.   The following are my personal observations and extrapolations from the show based on my conversations with customers, colleagues and walking the floor.

1. Internet of Everything – Not only are all things (machines, sensors, devices) being connected to the Internet but so are people and data, creating the Internet of Everything.  IoE is a fitting overall theme for CES – everything at the show is connected to everything else.  As Cisco CEO John Chambers stated in his keynote speech “IoE is bigger than anything that’s ever been done in high tech.”

2. New Next Generation TV… Again – You could be mistaken for thinking that CES is really the TV show.  Televisions are everywhere and every company seems to produce one.  Manufacturers are still promoting 3D television, but it has taken a back seat to the next big thing – spectacular ultra high-definition or 4K TVs – four times the resolution of typical HD TVs.

3. The World is Curved Read More »

An Architectural Approach to Location-Based Services

When was the last time you looked at your mobile device? Minutes ago? Seconds ago? We can’t seem to live without them, and in the consumer space, new mobile services are popping up it seems faster than your Twitter feed can handle. Below are mobile consumer services trends from the latest VNI Service Adoption Forecast (2012 – 2017) – you can see Mobile SMS, Mobile Commerce, Mobile Video, and Mobile Social Networking are on the rise, as is the number of devices per consumer.

Many organizations are looking for ways to leverage this upward trend in mobility and innovative mobile services for business benefit – whether it be for increasing customer satisfaction and communicating how the general population wants to receive communication, or offering Wi-Fi so users are able to consume the mobile services they want.

Cisco has made a big investment in mobile location-based services (LBS) over the past year with the introduction of the Connected Mobile Experiences (CMX) solution. CMX enables mobile users to adopt new innovative mobile services with an added benefit of relevance. Businesses can conduct mobile commerce, send texts, extend mobile video, or integrate mobile services with social media now based on the user’s location. Read More »
