What, Why, Where, When, How: The New FCC Ruling Around 5 GHz

You don’t need me to tell you to know that we are in the midst of a technology revolution.  It’s mobilizing the internet.  And it’s transforming the way billions of people around the globe collaborate, communicate, and connect to the internet.

•           The education customers I work with are incorporating video and mobile applications into their curriculum with up to a 100 students in an auditorium accessing the Wi-Fi network simultaneously.

•           Healthcare customers are relying on Wi-Fi to connect patients, devices and provide nurses instant access to medical records.

•           Manufacturing customers are increasingly using Wi-Fi to enable workers on the factory floor to have real-time video conversations with experts anywhere in the globe.

What do these things have in common?  They all depend on Wi-Fi for connectivity.  In these areas, and so many more, Wi-Fi has become a central way that people access the Internet.

The FCC released a historic decision on April 1, 2014 (adopted March 31)with regards to the use of 5 GHz spectrum. Although there were many technical aspects included within this decision, one of the most interesting was making the 5150-5250 MHz U-NII 1 band available for outdoor WLAN use. Read More »

Setting the Stage for the Cisco Mobile Workspace Solution with Citrix CVD

CiscoWotrkSpaceSolutionThe times keep changing: first there were devices, then there were apps, and today, if you don’t develop a strategy for enterprise mobility and get ahead of the trend, the mobile wave will leave you behind. A year ago, after talking with many of our customers, partners, and our own technical sales teams, we realized that IT organizations were facing enormous challenges when making the transition from simple BYOD to adopting an enterprise mobility strategy across the business. As is typical during such tremendous market transitions like mobility, IT organizations were spending a lot of time figuring out how to line up the pieces required to support a mobile workforce, sorting through and weighing the many technology and vendor choices.

Today in conjunction with our friends at Citrix, we are happy to highlight the  Cisco Mobile Workspace Solution with Citrixbuilt on the Citrix Workspace Suite. We are very excited to deliver this first of its kind, comprehensive solution to our customers. Today I’d like to take a step back and set the stage for the Cisco Mobile Workspace Solution with Citrix by taking you through our thought process in creating the right enterprise mobility solution for our customers.

Portland State University rolls out 802.11n and 5760 Series Controller

May 5, 2014 at 10:46 am PST

Portland State University is Oregon’s largest and most diverse public university encompassing 50 city blocks, eight schools, 226 degree programs, 29,000 students, including 1,700 international students from 91 countries, and 126,000 alumni. For the second year in a row, the US News & World Report has named Portland State University a top 10 “up-and-coming” national university in its Best College rankings, released online Sept. 10.

In 2010 Portland was one of the first schools to adopt the Cisco CleanAir capable Access Points 3502 to address the frequent sources of interferences found in a typical school environment. In this blog, I will describe how the students adopt technology to learn as well as share some details about our conversation with Tamarack Birch-Wheeles, the manager of Network Team in charge of the WLAN deployment with the 5760 Series Wireless LAN Controller.

The Future of Wireless: Times are Changing Before Our Eyes

We live in amazing times, ask anyone who ever had to look up a phone number in a phone book. In the past this was the only way you could find the number to your favorite restaurant if you wanted to make a reservation. Today, all we need to do is reach into our pocket or purse and grab our mobile device, open an application and in a few seconds (not minutes) we have the phone number. Not only that, but we can see the menu and make a reservation right from the device. Over time we have become dependent on carrying the world (both personal and professional) in our pocket. With mobility, we are always on, always connected: nothing—whether it’s your team’s latest score or that email from a vendor you need to send to your boss—is more than a quick search away.

What once seemed unfathomable, this way of always being connected is now commonplace. However, as the application developers sit and think of the next killer app, the IT team has to make sure the network can not only support this new app, but also assure the performance meets the higher and higher demands of new apps. This requires the network to be more application-aware. And the reality is that more applications that require higher network performance are coming at a faster rate. Add to it new devices that use these applications are becoming accessible to everyone. On top of that, the people that use these applications and devices are becoming more demanding in terms of reliability and experience. So what is an IT person to do?

“We were ahead of the times,” says Joseph Tufano, VP and CIO of St. John’s University. “But times have changed. You see it everywhere: for example, if you go to a basketball game on campus, and there’s a timeout, everybody is using their mobile devices.”

IT is always working to increase the wireless performance of the network. However, as more bandwidth becomes available, users increase their usage and consume that bandwidth. Read More »

Bring Out Yer Dead: 5 Steps to Eliminate 802.11b From Your Networks

Now that US tax day is over, we in the wireless field can get back to focusing on P1: optimizing and maintaining network performance. Keeping your network in good shape is like gardening: if you don’t pull out the weeds, it’ll never look as good as it could. My friend Jim Florwick detailed the gory bits of the 802.11b penalty with its awful lag in efficiency and absolute waste of spectrum. I write today to help give you the steps to act on Jim’s order to stop the madness.

I liken this process to a memorable scene from Monty Python: You must “Bring out yer dead.” However much the first standard insists it’s still alive, let’s all be honest with ourselves: 802.11b is dead.

In memoriam of the first amendment to the IEEE 802.11 wireless networking standard hailing all the way since 1999, 802.11b was superseded by 802.11a and g in 2003 which are much more efficient.  802.11n was available in draft form in 2007 and was ratified in 2009 while 802.11ac was ratified last September. A few years from now we should be planning the wake for 802.11a and 802.11g as well.

Now is the right time to bury 802.11b and reduce the drag on your network. Let’s be real: there is a reason cyclists are not allowed on the freeway, and an 802.11b device will slow everyone down. Here are 5 easy steps for eradicating your network of 802.11b and getting on your way towards higher speed wireless:

STEP    1.         Identify any 802.11b devices on your network

All of the latest Wi-Fi connecting devices are 802.11a/b/g/n capable. So how do you hunt down the 802.11b-only devices? You’ll be looking for older laptop and mobile clients (mostly before the year 2005).

Cisco Prime Infrastructure makes this easy for you with a report on clients by protocol. It will look like this:
