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.

It’s that time of year again in the US – Tax Time! That time of year where we review the previous year’s bounty, calculate what’s due, and re-evaluate our strategies to see if we can keep more of what we worked for. Things change; rules, the economy, time to retirement, and before you know it you find yourself working through alternatives and making some new decisions.
Anyway, as I was working through the schedules and rule sheets, my mind wandered and I started to think about Wi-Fi and the taxes associated with it. In my day job, I often play the role of forensic accountant. Like a tax accountant, I’m always looking for a way to get more or understand why there isn’t more already. So along those lines, lets talk about a little known tax that you may well be paying needlessly. I’m talking of course about the dreaded 802.11b Penalty.
Wi-Fi protocols like 802.11b are referenced by standards committees for the workgroup that develops them. In the 2.4 GHz spectrum, there is 802.11b, 802.11g, and 802.11n. Back in 1997, 802.11b was the first modern Wi-Fi protocol ratified by the IEEE and it allowed transmissions of 11 Mbps, a major jump forward from the previous 2 Mbps that was possible with the original 802.11 standard.
After 802.11b came 802.11a, and then 802.11g. Both of these protocols where a radical departure from the simplistic 802.11b structure and employed Orthogonal frequency-division multiplexing (OFDM) modulation (now standard in every 802.11 protocol created since then). OFDM allowed for Read More »

As a Product Manager there is some anxiety but more of an excitement around introducing a platform to the market. Today I am proud to be part of Cisco team that is bringing to market the Cisco Aironet 2700 Series Access Point. What it offers is a tremendous amount of power at a very attractive price point.
We all know Wi-Fi is here to stay and is expanding all around us rapidly. That need for speed is exciting. But what does that mean? Not everyone feels comfortable being on the cutting edge. Many of our customers are not as concerned about chasing the future and have more limited budgets that they hesitate to put down for the best AP knowing there are lower priced options. At the same time, everyone is aware technology moves ahead with or without you, so they don’t want to give up lot of the new capabilities by going totally to the other extreme of not upgrading at all. What they want is something that’s going to last for a while that gives them the advantages available today, but not have to invest a lot to get it. I equate this to buying something like a car. A year ago when I was in the market to buy a new car I didn’t want to sacrifice whole lot of options but if there was one or two options that I could give up in order to save a bit of money, I was okay with that.
This is similar to what Cisco is offering with Aironet 2700 Series. Customers have to choose something that they can utilize in their network that is better than any of the competitive solutions out there, truly built-for-purpose, sleek design on the outside yet tough on the inside and very powerful.

As more and more 802.11ac devices come to the market this year, businesses need to make sure the best possible 802.11ac wireless infrastructure gets deployed to make sure those 802.11ac end points are performing at both the best possible data rates and application throughputs to maximize the move to 802.11ac.
Cisco’s Aironet 3700 with HDX Technology does just that. If you’re thinking that the 3700 is just another 802.11ac AP, think again: not all 802.11ac AP’s are created equal.
To demonstrate this, let’s take a Cisco 3700 access point..
When you open a Cisco AP, you will see dedicated memory (RAM) on the radio chipset itself (one on the 2.4 GHz radio, another on the 5 Ghz radio) to ensure the RF packets get processed “onboard” each radio instead of “offboard” in order to reduce latency and any packet processing collision from memory contention on the AP. Additional packet processing can be handled on the “offboard” memory that is part of the network processor portion of the AP platform as well. This unique, innovative ASIC-based Wi-Fi chipset by Cisco exemplifies the built-for-Purpose design, and is the hallmark of Cisco’s 3700 Series AP.
Contrast this with the competitive landscape that claims to be Purpose-Built, but in reality is leveraging off-the-shelf merchant silicon-based 802.11ac WiFi chipsets. Read More »

Cisco has been placing a lot of emphasis on delivering solutions that provide insights and understanding on how customers, patients, visitors and communities interact with their physical environments. Mobility and leveraging mobile devices in the environment has revealed itself as a very powerful way to gather critical business intelligence. This business intelligence is highly impacted by the resolution of the location-data and the demand to improve resolution and accuracy is increasing quickly. Apparently, this has not been missed by UBM. This year Cisco is honored to be selected as a Best of Interop Finalist for the Wireless award category for our innovations in improving location data resolution calculations.
It’s an honor to be recognized for our innovation and technological advancements in wireless, and we wanted to share a bit more about our submission with you.
What are Location Data Resolution Calculations?
Many systems acquire location analytics by relying solely on the probing that occurs from a mobile device to an access point. Unfortunately, this approach is delivering diminishing returns. It puts location analytics at the mercy of the mobile device vendors. What I mean by this is that as mobile device manufacturers look to improve mobile devices in regards to OS, drivers and battery life they are reducing the frequency of the probing from the mobile device. In addition, different mobile device manufacturer use different probing intervals. The need to do this makes sense from the mobile device manufacturer perspective, but it has an impact on the accuracy of the data acquired when representing movement of end users in the physical environment. If a user is recognized when they walk in the environment and then is identified a minute later, there is a lot of movement that can occur in that time. But the analytics only sees two data points and draws a straight line. Not a very accurate representation.
Cisco is leveraging what we know best, the network, to supplement the device probing. Bringing in network data allows us to gather higher data resolution regarding mobile device movement, equating to a more accurate representations of end user movement in the environment.
