Guest Blog: Migrating High Density University Networks to 802.11ac

Editor’s Note: This is a guest post by Joe Rogers, Associate Director of Network Engineering for the University of South Florida (USF). Hear Joe speak about his experiences with next-generation wireless in high density environments on next Tuesday’s webinar:  ”Migrating Enterprise Networks to 802.11ac” at 10am PST (Dec 17) (Register here)

Joe RogersJoe Rogers is the Associate Director of Network Engineering for the University of South Florida.  He is a graduate of USF’s Computer Science and Engineering program and has worked as a network engineer at USF for the past 20 years.  He is currently responsible for all aspects of USF’s network which provides connectivity to over 100k devices across three campuses.  He’s held a CCIE routing and switching certification since 1999.  When not working, he’s an avid mountain biker (if you can call it “mountain” biking when you live in Florida).

Universities face some of the most complex design challenges in wireless networking.  Our user population is highly mobile, bandwidth-hungry, and often simultaneously using at least two wireless devices in rooms with hundreds of their classmates.  The wireless network isn’t simply a convenience to them.  It’s critical to their educational success as many of the students are taking tests or working on assignments across the network.

At the University of South Florida, we support over 20,000 concurrent wireless users on our network of over 4,000 access points.  We have more than 90,000 unique devices registered this semester.  Our biggest challenge is designing the wireless network for the device densities in our large classrooms and popular study areas.  In these locations, we often have a thousand devices in a few hundred square feet of space.

We heavily rely on band select to place as many devices as possible on 5Ghz where more channels are available.  Unfortunately many devices such as older tablets and smart phones simply don’t have an 802.11a/n radio.  So we must carefully RF engineer the environment with smaller cells to provide the necessary coverage density.

Summary: An Innovative Infrastructure to Capture the Value of the Internet of Everything

The Internet of Everything (IoE) is no longer a prediction. It is reality. As I think about the infrastructure needed to truly capture its value, I immediately think the network needs to be:

  • Agile
  • Intelligent
  • Secure

Why are these qualities a necessity for a thriving programmable infrastructure? Simply, it will allow enterprises to be ready for today’s business needs and tomorrow’s new business models.

Organizations must be able to quickly, intelligently and securely leverage their infrastructure to keep pace with business transformation driven by emerging cloud and mobile technology.

Today’s world is dominated by what Gartner Vice President David Cearley calls the “four powerful forces: social, mobile, cloud and information.” An infrastructure must increasingly demonstrate it can add value to the business, by rapidly and securely rolling out new services, apps and capabilities in a connected world.

An Innovative Infrastructure to Capture the Value of the Internet of Everything

As the saying goes, the constants in life are death and taxes. We all know there are more than those two, including change and its counterpart, disruption. Business success will result from responsiveness and adaptation that will happen at a rate and with intelligence that we’ve only begun to get our heads around.  And, most CIOs I speak with are asking about how they can adapt and scale their infrastructure to be prepared as the Internet of Things evolves into the Internet of Everything.

This change brings big implications for IT. The role of IT is changing, in the face of cloud and mobile apps, and the growing understanding that every company is a technology company. From the consumerization of IT to what Gartner Vice President David Cearley calls the “four powerful forces: social, mobile, cloud and information,” IT must increasingly demonstrate it can add value to the business, by rapidly and securely rolling out new services, apps and capabilities in a connected world.
