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.

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of the first amendment to the IEEE 802.11 wireless networking standard hailing all the way since 1999, 802.11b was superseded by 802.11a and g in 2003 which are much more efficient. 802.11n was available in draft form in 2007 and was ratified in 2009 while 802.11ac was ratified last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:

Founded in 2007, RetailMeNot.com is the largest digital coupon site in the US. They help hundreds of thousands of customers save money when shopping online. They are headquartered in Austin Texas, in the hip “Live Music Capital of the World”. Since the company went public in 2013, the company has doubled the number of employees from 250 to over 500.
In previous blogs, I have covered what is AVC, SuccessEHS and how Plixer’s Scrutinizer accepts Netflow, sFlow and IPFIX exports. This post will cover how these key products are combined by RetailMeNot in their WLAN deployments to optimize and support this fast growing company.
Recently Michael Patterson, the Founder and Product Manager at Plixer, Matthew St. Jean the Marketing Manager at Plixer and I had an opportunity to talk to Tim Tyndall, the Lead Network Engineer at RetailMeNot. Tim shared with us the highlights of the wireless LAN deployment and explained how they use Cisco Application Visibility and Control and Plixer’s Scrutinizer to stay in control of how their WLAN is being utilized.
Tim described the environment and culture that has become a huge part of the company’s success. RetailMeNot provides hip new offices for its employees with open work spaces and other awesome perks.
The Cisco powered wireless network supports this initiative. In fact, nearly all network connectivity is wireless. He said that employees are issued a laptop by the company and many carry in their own smartphones and tablets as well; Most of those devices being from Apple.
Employees can roam freely with reliable service that spans the company’s five floors. Even during large meetings where access density increases dramatically, service continues without any interruptions and the performance metrics they can obtain using NetFlow is exceptional and reinforce that the traffic is optimized.

The University of Nevada, Las Vegas (UNLV), founded in 1957, is located in the heart of showbiz industry in Las Vegas. The school offers higher education programs ranging from business, engineering, fine arts and music, and science, and professional schools such as dental medicine and law.
The school’s mascot, Hey Reb, was recently featured on Hulu’s “Behind the Mask,” and you may recognize the Southern Gym during the dance scene between Elvis Presley and Ann-Margret Olsson in the movie Viva Las Vegas.
With over 24,000 unique WLAN users per day, 1.1 gigabytes of throughput per second, and more than 50 wireless access locations across campus providing WLAN coverage, this educational institute demands a massive Wi-Fi network.
In the previous blog, we highlighted some of the Bonjour enhancements of the 7.5 software release and the deployment of Bonjour at St. Margaret’s Episcopal School, a K-12 school. In this blog, we will describe details about UNLVs WLAN deployment, how they use Bonjour services, and give you an insight into rapid pace of innovation necessary to support this technology in the education arena.

Today MWC 2014 came to a close in Barcelona having been another resoundingly successful event.
Mobile operators and Service Providers have displayed ever increasing interest in Monitization of their infrastructure especially via WiFi and Cisco’s CMX solution.
During the week I had many conversations with SP’s from across the world while very different geographies and facing different challenges, a common theme among the meetings was how can Cisco help us find ways to generate new revenue streams and new monetization models.
At MWC we showed various demos that show how this can be achieved and provide many interesting ideas to the customers to help them think about their own businesses and how they may be successfully applied.
One demo was how various components of Cisco’s SP Architecture can improve services and provide montitization opportunities to a fictitious hotel resort chain with wired and wireless small cells, SON & Analytics all working together. Read More »
