There is no denying it: your employees and customers are streaming video. While the volume of that streaming dramatically peaks around game times during the World Cup, it should be no surprise that today, mobile applications, largely video, are increasing mobile traffic across networks. That’s straight forward: apps + video = bandwidth drain. Combine that with the fact that people are touting multiple devices--think a laptop and a smartphone, maybe a tablet, too. This means high density--lots of clients and devices on a single network. These circumstances trigger three potential yellow cards to cross an IT person’s mind – let’s see how we can avoid them.
YELLOW CARD #1: Rich Media Optimization
As an end-user, the common expectation is that I should get the same crisp, clear, rich media or video experience across all platforms—I don’t care if it’s my phone, my tablet or my laptop: make it high definition. This is harder said than done.
It is not easy to provide the same rich media experience across wired and wireless devices. Traffic from wireless devices has to travel all the way back to the controller in a data center and then back to an access switch before reaching its destination. It’s called the hairpin effect. The result is that video over Wi-Fi could look grainy. That won’t do for the current generation of high definition junkies. Read More »
One of the best times I always have at Cisco Live involves getting to play ‘TV Anchor’ for the various live shows we stream. Well the Cisco TV team lets us use their equipment to do a live version of TechWiseTV each afternoon as well. Now honestly, I do plan these out…a little. But our day three show is generally a ‘hey…what do we WANT to do” kind of show. Planning for day 3 simply involved asking Jimmy Ray and Tina what they wanted. We had TWO wireless cameras this year to play with so it felt like we could do a little more. As for me (with input from the hillbilly of course), we wanted to take advantage of Wireless Stew’s presence and get him up to tell his story…so that is how we started.
Stewart Gouman’s is a fantastic fan of the show, running his wireless consultancy and very informative blog from the Great White North. He has sought us out in just a few visits over the years stopping by the studio in San Jose or catching us while at Cisco Live when we all end up in the same place. Watch the show and get his career and community advice.
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.
Number of students: 15,000 of which about 2000 stay in residence halls
Number of teachers/staff: 2000
# WLAN clients: Approximately 8500 concurrent clients
Access-Point Model and Units: 1200 units of AP models including AP702W, 3502, 3602, 3702, 1550 and a few older Access Points which are being phased out
Controller Model and Units: 2 Pairs of WiSM2 operating in 18.104.22.168
Switch Models: Various models 2960, 3650, 3850, 3750X and 6500
Prime Infrastructure: 1.4.2
Mobility Services Engine: 7.6
Deployment Details: We talked to Christopher Johnson, the Senior Infrastructure Systems Analyst II at Northern Kentucky University to capture some of his thoughts around their choice of this solution and the associated benefits. Read More »
Johns Hopkins Medicine is one of the leading health-care providers in the US. The Johns Hopkins University School of Medicine is consistently ranked as one of the top Medical Schools in the US and the Johns Hopkins Hospital is consistently ranked #1 in the US for 21 years in a row! In a previous blog in 2012, we described how the Cisco Wireless LAN controller 7.5 release enables wireless networks to recover with no client re-authentication in the event of a primarily controller failure. In this blog, I will share more details about unified access deployment at the Johns Hopkins Hospital with particular focus on the High Availability design.
Patients are the focus at Johns Hopkins Hospital. Johns Hopkins uses state-of-the-art technology in their hospitals to ensure that patients get the latest advances from surgical tools, radiologic imaging suites with the best diagnostic capabilities to something as humane as sound-absorbing private rooms for each patient.

This week we finished our biggest product announcement in recent memory.The various teams worked hard to bring out to our partners and customers products that delivered maximum quality, flexibility and value.
One of the products included was the new Cisco Small Business WAP371 Wireless Access Point. This Access Point is the first 802.11ac model in the portfolio representing a paradigm shift in the way you as a business owner can improve wireless performance for your business. This new model has a dual radio, includes a Gigabit Ethernet (GbE) Power-Over-Ethernet (PoE) LAN port and has the ever-popular Single Point Set-up capability. The WAP371 also features Captive Portal for guests, and like the rest of the wireless portfolio, offers simple set-up and deployment with an intuitive user interface and set-up wizards.
But this release raises the question regarding exactly why you should think about upgrading your small business wireless network.
Nasser Tarazi, Product Manager for the Cisco Small Business Wireless Access Points, talks about reasons why to take a look at the all-new WAP371.
“Right now is a good time for Small Businesses to consider upgrading their wireless networks from older 802.11 technologies to 802.11ac. First-off, 802.11ac is three times faster than it’s predecessor, 802.11n. The use of Multiple-Antenna, Multiple-in, Multiple-out technology (MIMO) reliably delivers this boost in performance providing for a much better user experience.”
Nasser goes on, “We expect over 70% of mobile devices will be 11ac-enabled by 2016. Like mentioned before, 11ac is three times faster than 11n, so from business-critical to social media applications, improved wireless high-speed performance will ensure your applications will run smoothly, reliably. Also, range is better, even for 11n enabled devices.”
“Security is on every business owner’s mind. 802.11ac is more secure than 11n. And in fact, 11ac is also more power efficient, which can result in a 30% improvement in battery life for your wireless devices such as mobile phones and tablets. Finally, 11ac provides for greatly improved client density, so high-client use cases such as schools, churches, and other organizations will greatly benefit from the upgrade to 11ac.”
