Joe 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. Read More »
When I arrived in early June for my 12-week internship in Cisco Corporate Affairs, I began to read You + Networks = Impactxeverywhere on the Cisco Corporate Social Responsibility (CSR) website. For me, it was just a tagline – part of a marketing campaign for Cisco CSR. I didn’t understand it, and wasn’t sure if I completely believed it. It wasn’t until I became a part of the Cisco CSR family and plugged myself into the equation that You + Networks = Impactx became much more than a tagline; it became the heart of my work at Cisco this summer.
During my 12-week internship, I learned how human and technology networks can multiply impact on people, communities, and the planet.
It’s no secret that mobile devices are playing a larger part in today’s businesses. With the fast pace of mobility adoption by consumers, network usage has started to outrun the infrastructure of most enterprises’ mobile networks. Enterprise IT managers are struggling to keep up with mobility’s effects on workplace productivity and requirements.
Among the growing trends that weigh heavily on the minds of most network IT professionals is bring your own device (BYOD). The growth of bandwidth-intensive applications, like video streaming, and the user expectations of always-on network and application performance also place heavy demand on organizational infrastructure.
802.11ac is the next generation of Wi-Fi, designed to give enterprises the tools to meet the demands of BYOD, high-bandwidth applications, and the always-on connected user. This Wednesday we will be hosting a workshop to discuss the benefits of 802.11ac, and how to optimize it for high density and high bandwidth to benefit higher education. Students, typically early adopters of wireless technology, usually bring 802.11ac in the form of the latest laptop, smartphone, and tablet that support this new technology. Read More »
For today’sdigital generation, collaborative learning is no longer a novelty – it’s an expectation. Students are consuming information in new and different formats – video, Internet, virtual classrooms. These are all tools that are changing the face of education. To make this transformation a reality, students, faculty and administrators need to reliably connect with the people and resources they need whether they’re using their desktop or mobile device, at home or in the classroom.
For schools looking to take the plunge like Katy ISD, what’s the best approach to take?
As I discussed in this recent blog post about , the best approach is looking at the problem with the big picture in mind.
With Cisco Unified Workspace, schools can build a scalable and secure network that will serve as a strong foundation for the future. Watch the video below to see how Cisco’s solution is designed with utility to unify voice, video, data and secure access on any device and at any location.
Equipped with Cisco’s smart collaboration strategy schools can combine voice, video and mobility to create a classroom that allows faculty and students to collaborate efficiently and securely.
As a father of future college students, I’m excited that Cisco’s announcement yesterday about the Internet of Everything (IoE) Economy may finally transform college education to provide graduates with the real-world skills needed by businesses today — and tomorrow.
Before I jump too far ahead, let me explain what Cisco announced. Cisco estimates that there are currently about 20 billion things connected to the Internet, yet more than 99 percent of physical “things” remain unconnected. Obviously, there is a huge opportunity to connect the unconnected. IoE aims to do just that by adding people, process, and data to the things that are connected to the Internet, such as devices, sensors, and machines.
To help businesses understand how to benefit from IoE, Cisco IBSG’s Economics Practice calculated the amount of Value at Stake in the IoE Economy. Value at Stake is defined as the value that will either be newly created or will migrate between lagging companies and industries to the leaders over the next 10 years based on their ability to harness IoE. We did this by taking a bottom-up approach of selecting and analyzing 21 industry-specific and cross-industry use cases, including the one I’m discussing here: connected private college education.
From this analysis, the team determined that there is $14.4 trillion of Value at Stake in the Internet of Everything Economy over the next decade. The five main drivers of this Value at Stake are:
1. Lower costs from improved asset utilization ($2.5 trillion)
2. Greater efficiencies from improved employee productivity ($2.5 trillion)
3. Less waste from supply-chain and logistics efficiencies ($2.7 trillion)
4. Greater lifetime customer value from improved customer experiences ($3.7 trillion)
5. Increased return on investment (ROI) and new revenue from faster innovation ($3.0 trillion)
So, how much of this value comes from improved education? Read More »
