Ever since the much anticipated 802.11ac standard was ratified and supported by Enterprise class access points (AP), I’ve asked myself the question that perhaps other network and Radio-Frequency (RF) engineers have: how much of the theoretical 1.3Gbps 802.11ac data-rate can I really deliver to my users and what is the overall throughput experience when I deploy at scale or in high-density (HD) scenario? On the surface, it may seem intuitive that I should allocate 80MHz to my 802.11ac radios to achieve the best throughput BUT as it turns out, this approach has limited scale and may lead to less total throughput than a smaller 40Mhz channel – so in this case; less may be more!
This is due to the fact that while in a single-cell (AP) scenario (say 5000 sq. ft) it is realistic to expect most capable devices can reach 1.3Gbps (1Mbps of throughput) with 3 spatial stream (SS) & 80MHz (e.g. MacBook Pro) and 433Mbps (300Mb/s of throughput) with 1 SS & 80MHz (e.g. iPhone 6) BUT this throughput degrades quickly in a multi-cell environment where co-channel-interference (CCI) from neighboring APs can dominate. So we need to look at the primary CCI contributors, which are: Read More »

Rijksmuseum in the Netherlands is one of the top 10 art and history museums in the world.
We live in an era where information is available in the palm of our hands and traditional institutions such as museums are inevitably facing the consequences of this. Even though the museum dates back to the 1800’s with artifacts from the middle ages, they have embraced modern technology to adapt to the changing landscape. This was as a matter of survival considering the competition from other institutions.

With the growing influx of new mobile devices, connected things, bandwidth intensive applications and more data, the network is more relevant to business success than ever before. Back in June of 2012, Cisco saw that we needed to move away from multiple network systems loosely linked together to an agile and simple infrastructure, streamlined policy and centralized management would be needed to support new business demands. We called it Cisco Unified Access and we aligned the solution to three pillars: One Network, One Policy and One Management.
For the last few years, we have focused on delivering new products and functionality under this Unified Access model. Below is a timeline of products released as part of the Unified Access framework. Cisco lead the way in delivering gigabit 802.11ac Wi-Fi., converged wireless control in access switches and through the acquisition of Meraki – a complete cloud-managed network solution.
The timeline above doesn’t represent every feature and function we have delivered, but it shows Cisco’s commitment to this Unified Access model, both from a cloud-managed and on-premise solution perspective.
Today, Cisco is announcing a number of new products and new functionality to existing products that will help mobilize the workforce, secure the business and increase IT agility. The announcement includes the following: Read More »

For the past 125 years, Globe University has focused on hands-on training to ensure the career success of students offering associate, bachelor’s, master’s and doctorate degrees, as well as diploma and certificate programs. A recent article from the magazine Campus Technology showcases how they are pioneers in adopting new technology in the classroom. They have a systematic program dubbed as edUX (Educational User Experience) to integrate tablets into every program they offer. In addition, they work with an e-book platform called VitalSource and use Blackboard technology in the classrooms. Students are also encouraged to use technology. For example, math and science instructors use videos from the Khan Academy, the business school recommends Twitter accounts and the librarian encourages using EasyBib for book citations.
In the past few years Apple introduced mDNS services such as AppleTV, file servers and printers that use a Zero Config-based technology for service advertisement and discovery called Bonjour. While this technology works well in the home, which is a flat L2 network, when it is deployed in a K-12 or enterprise, it does not lend well over a L3 network. In 2013, Cisco introduced Bonjour Services Directory on the AireOS 7.4 and Service Discovery Gateway (SDG) on the Catalyst 3K, 4K, 6K and 5760 Series controllers with release IOS-XE 3.3. The future releases further optimized the functionality in 7.5 release, 8.0 release and IOS-XE 3.6 release. In this blog, I will share deployment details of unified access at Globe University and how they use Application Visibility and Control (Cisco AVC) to track applications in their network and the Bonjour Services Directory to manage AppleTVs in the classroom.

The North American IPv6 Summit is the largest annual IPv6 event in North America, designed to educate about IPv6 and the current state of IPv6 adoption. We were honored to receive industry recognition of the Cisco’s IPv6 leadership and continued innovation with the Best of Show Award of Product and Service for the Cisco Wireless Controller.
As you read about earlier this summer, Wireless Release 8.0 added a cornucopia of features to our wireless offering, many of which are targeted specifically for upcoming technologies, including IPv6. Let’s look back to see how far we’ve come:
Anticipating the growing demand of the next generation IP and eyeing the arrival of World IPv6 day, Cisco released the first support for IPv6 in its’ Wireless LAN Controller (WLC) software version 7.0 in 2011. There has been a steady progression of feature support ever since. Client mobility appeared in version 7.2 a year later in time to celebrate the launch of IPv6 on the global Internet.Then came the release of 7.4 and it’s support of First Hop Security tools, enabling organization’s to go beyond the lab and deploy IPv6 in a safe, secure manner.
