Englewood Cliffs public schools system, based in Bergen County, New Jersey offers classes to children from K-8 grades. The school system consists of two schools, the North Cliff school serving grades from K-2 and the Upper school serving grades from 3-8. The school system utilizes cutting-edge technology to assist learning from the classrooms equipped with technology, the 1 to 1 computer tablet initiative to the 6th, 7th and 8th graders to upgrading to the best-in-class wired and wireless infrastructure needed to support the advanced technologies.

Gartner has released their 2014 Magic Quadrant for Wired and Wireless LAN Infrastructure. For the 3rd year in a row, Cisco is recognized as a leader in both vision and execution. We believe this Gartner recognition is validation of Cisco strategy and investments for unified access, policy management and cloud managed solutions.
Cisco’s position in the Wired and Wireless Gartner MQs has been consistent over the past 3 years as the market landscape has shifted we believe validating our commitment to meeting shifting customer priorities and requirements.
The 2014 Gartner Magic Quadrant for the Wired and Wireless LAN Access Infrastructure (Authors: Tim Zimmerman, Andrew Lerner, Bill Menezes; Published 26th June 2014) reflects the evolution from prior years and highlights what customers are looking for:
“With limited growth in IT resources, administrators require one network management application, one access security solution, one guest access application or one policy enforcement solution with the flexibility to be deployed in a public cloud, private cloud or on-premises. This integration reduces the costs associated with the upfront capital expense of multiple network service applications each dedicated to either the wired infrastructure or the wireless or cloud components. This savings is also extended to the ongoing software maintenance costs of all access layer management, security and policy enforcement components.”

In my last blog on 5 GHz spectrum, I discussed the recent FCC ruling that permitted outdoor access points to use the U-NII 1 band (5150-5250 MHz).
But the story doesn’t stop there. As mentioned last time, there are significant technical challenges to using the 5 GHz band. It is not cleared spectrum. It contains incumbent uses that are important for national security and public safety. Therefore, it is imperative that Wi-Fi not create harmful interference to these incumbent systems. Cisco will not settle for less.
On the topic of interference, a particularly interesting component of the same FCC ruling that opened the U-NII1 band for outdoor AP’s is that it also re-opened the Terminal Doppler Weather Radar (TDWR) band (channels 120, 124, 128) with new test requirements for DFS protection. Hold on, let’s backtrack a bit before diving into what this means:
What is TDWR?
In brief, Terminal Doppler Weather Radar (TDWR) “is a Doppler weather radar system used primarily for the detection of hazardous wind shear conditions, precipitation, and winds aloft on and near major airports situated in climates with great exposure to thunderstorms in the United States.” TDWR uses the frequency band from 5600-5650 MHz which is why wireless network equipment needs to be proven to “do no harm” to TDWR. If you’re curious for more information on TDWR, then please click here and/or here.
A Brief History
Many of you reading this will recall that the FCC closed the use of the TDWR band several years ago as the result of numerous reports of wireless equipment creating interference with TDWR. Read More »

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.

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.
