Staying Connected at Northern Kentucky University

July 3, 2014 at 9:07 am PST

Northern Kentucky University is among the fastest growing universities in Kentucky. It hosts over 15,000 students with about 13,000 undergraduate and 2,000 graduate students. The goal of the wireless program at NKU is to provide secure, robust and ubiquitous wireless access throughout the campus, both indoors and outdoors. This ensures that students always stay connected and feel at home. The classrooms are equipped with smart technology to ensure that the teachers can benefit from technology when collaborating with students. The IT team has blanketed the libraries, the classrooms, the dorm-rooms as well as the outdoor areas with Wi-Fi. In the previous blog in 2012, we described how the Cisco 7.5 release allows networks to recover with no client re-authentication in the rare event of your primarily wireless LAN controller goes down.

The Momentum of 802.11ac Moves into the Real World

Wireless is enabling change everywhere. According to Cisco’s VNI Global Forecast, wireless traffic will bypass wired traffic 40% by the year 2017. This is evident by the way many organizations are using Wi-Fi technology.  Take healthcare providers as an example: many hospitals today rely on Wi-Fi to provide seamless clinician roaming, improved efficiency and patient care--not to mention patients’ relatives and friends who expect to connect to guest Wi-Fi. And then there is education where we are seeing both universities and K-12 schools faced with more and more students coming onto campus carrying mobile devices with bandwidth intensive applications like video.

The explosion of high performance applications and the number of clients using them is a big reason why 802.11ac adoption is happening at a rapid pace. 802.11ac as a standard addresses the performance needs of applications while providing a robust network that handles a growing number of client devices. Cisco provides our customers with a unique solution to meet the high density requirements with a technology suite called Cisco High Density Experience (HDX). HDX helps Cisco customers prepare beyond 802.11ac and addresses the key aspects of any network that is challenged by the high density of large numbers of clients on the network and increasing performance demands of bandwidth intensive applications.  Deploying 802.11ac with Cisco’s HDX Technology will provide a relief from the bandwidth demands while also making the overall Wi-Fi network more efficient.

With this in mind, we are hosting a webinar on June 26th where we focus on 802.11ac Standard, Cisco’s 802.11ac solution including our HDX Technology and how it can be used in various networks. We have also invite Joe Christoffersen who is the Director of IT at Katy Independent School District in Katy, TX to provide his unique perspective on how Katy ISD is deploying 802.11ac, how it will affect the performance of his network and the benefits he expects from this technology.

The webinar is next Wednesday at 1:00PM PDT. Here is the registration link. If you miss it, we will have it available on demand here shortly after.

802.11ac: That’s the Answer. What’s the question?

Everybody’s talking about 802.11ac, but we’ve sensed some confusion for next steps as far as how CIO’s and IT organizations should be approaching the new standard.

3700internal2Should I move to 802.11ac?

You’re probably thinking: Chris, you’re a leader at Cisco, of course you want me to migrate to 802.11ac. That, my friends, is where you are wrong. There is no simple answer to the question of whether you should move your network to 802.11ac. Here’s my simple rule of thumb:

There is no premium for 802.11ac from Cisco. If you are deploying new Access Points’s today, you should be buying 802.11ac. If you’re not buying, you are probably satisfied with your network and how it will handle the growth of more and more clients associating with your network and the bandwidth demands that come with that client demand. If you feel you have a plan to handle this demand, then you are one of the few that can pass on 802.11ac.

That said, there is a strong ramp up for Cisco 802.11ac products in the market, the AP3700 is the fastest ramping access point in our history and we have yet to see if the AP2700 will claim that crown in the coming months. ABI Research estimates that currently 50% of new device introductions are 802.11ac enabled, a statistic expected to increase to 75% by the end of 2015.  This is enough proof of the overwhelming interest in adding the benefits of 11ac to networks. Let’s take a step back and consider the basics of why people are moving to the new standard.

Why .11ac?

Today, everything is about getting what we want, when we want it. Instant gratification. It’s not just the millennials—we’ve all been conditioned to expect things within seconds. Could you imagine the days pre-Internet if you had the capability for on-demand movies? 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.

School Board of Sarasota County Prepares WLAN for 802.11ac

May 16, 2014 at 9:30 am PST

Sarasota County Schools includes 24 Elementary Schools, 9 Middle Schools, 8 High Schools and various Technical and various Special Centers. It houses about 40,000 students in about 250 buildings. The Sarasota School IT Team believes in using the best-in-class technologies to provide the optimal connected experience for students, faculty, staff and guests.

This next generation pervasive WLAN network enables students to collaborate with each other anywhere on the campus and with the teachers in the classroom. In the previous blog, we described how Bowdoin and the Pinellas County have embraced the IOS based 5760 Series controllers. In this blog, we will cover more details about the recent upgrade of the Wireless LAN Controller from the previous model WiSM to the new model 5760 and describe highlights of our conversation with xx about the WLAN deployment itself.
