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of the first amendment to the IEEE 802.11 wireless networking standard hailing all the way since 1999, 802.11b was superseded by 802.11a and g in 2003 which are much more efficient. 802.11n was available in draft form in 2007 and was ratified in 2009 while 802.11ac was ratified last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

Previously I have blogged about No SSID Outage and No Client Reauthentication whereby even if your Cisco Wireless Controllers were to fail due to any reason, the clients will NOT experience any downtime due to Stateful Failover functionality to a Standby Controller. What could be better than that? Controllers that never go down!
A picture is worth a thousand words! As you can see the above the WEBGUI on a 5508 series wireless controller shows that, it is running 7.0 code which was an MD release, has been operational for over a thousand days or over three years! Read More »

As the famous saying goes, “Good things come to those who wait”. Delayed gratification – person’s ability to forgo a smaller reward now for a larger reward in the future – has been linked to better life outcomes as demonstrated by the often cited Stanford Marshmallow experiment and others. In most cases though, it requires a degree of self-control not easily achievable in today’s fast paced, ever-changing world with new mobile devices, protocols and technologies.
If you are one of the Cisco Wireless customers currently deploying Release 7.0 MD and waiting for the next Cisco Wireless Software Maintenance Deployment Release, the wait is over!
Release 188.8.131.52 has achieved Maintenance Deployment (MD) status.
Release 184.108.40.206 is the recommended MD release for all non-802.11ac deployments. For 802.11ac deployments, Release 220.127.116.11 (Release 7.6 Maintenance release 1) is the recommended release.
For additional details on Software Release Recommendations and Guidelines, see Guidelines for Cisco Wireless Software Release Migration
Below are top 10 reasons (in no particular order) to upgrade from the current 7.0 MD release to the latest 7.4MD Release.
10. FlexConnect (improved and rebranded H-REAP) with efficient AP upgrade across WAN, BYOD policies support, Flex ACLs and split tunneling. Read More »

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.
