If you recall, back in the early days of 802.11n, the Wi-Fi Alliance (WFA) rolled out the 802.11n certification program in phases. Here we are several years later and in that same fashion, the WFA has split the IEEE 802.11ac specification into two certification phases: Wave 1 and Wave 2.
Last week we announced the availability of our 802.11ac Wave 1 Module for the 3600 Access Point and along with that, our intention to develop an 802.11ac adaptive radio module that will support the second phase of 802.11ac, or Wave 2. Most of the 802.11ac discussion in the last year has been focused on Wave 1, so we want to kick off the conversation about the second phase, Wave 2.
If Wave 1 promises increased wireless performance to address the increasing demand for higher performance including growing number of clients demanding higher performance for applications such as HD video streaming, then Wave 2 will stun you with its ability to provide even more throughput beyond the 1.3Gbps that Wave 1 provides as well as a number of other features that will further improve wireless connectivity. It is like taking a really good rock song and adding more cowbell to it.
SNL jokes aside, with the additional features packaged in Wave 2 comes the opportunity for further innovation in Cisco’s Wireless portfolio. We feel that it is important to stay ahead of the technology curve so that customers can plan and benefit from these advances sooner rather than later. So let’s discuss what features are coming with 802.11ac Wave 2. Read More »

What’s new and exciting with EIGRP (Enhanced Interior Gateway Routing Protocol)? Actually, lots… First a bit a background on EIGRP.
EIGRP is an advanced distance vector routing protocol used extensively by enterprise customers. It is very popular because it is simple to deploy and support. Some major attributes are:
- EIGRP does not mandate many network design requirements and is therefore perceived as “forgiving” and “flexible”. For example, EIGRP does not require support for multiple routing sub-domains or Areas.
- While route summarization is a recommended best practice to minimize route table size, it is optional with EIGRP.
- EIGRP can scale to support thousands of routers in a Hub and Spoke configuration. The Hub and Spoke design is especially popular in WAN networks.
For additional information on EIGRP, please click here. There is also a great BLOG that compares EIGRP and OSPF that I think you will find informative and is posted here.
While EIGRP has a large customer following, some customers have hesitated because of concerns of EIGRP being “proprietary”, which would prevent them from multi-vendor network support. In some cases this has caused customers to design their networks to limit usage of EIGRP, even though they would like to deploy it ubiquitously. One result has been non-optimal network design and traffic flow, resulting from multiple IGP (Interior Gateway Protocol) redistribution points.
That brings me back to what is new and exciting with EIGRP. Read More »

In light of the recent announcement of MSE Release 7.4 and Advanced Location Analytics Availability, we thought it would be timely to pick up where we left off on our MSE blogs series. In the first two, my colleague Anshul Tyagi covered how the MSE optimizes the CleanAir experience and discussed other MSE enhancements. Now that we have expanded the MSE to cover advanced location analytics, let’s use this blog to dive deeper into how to monetize your Wi-Fi infrastructure using our new functionality.
So you have a Cisco Wi-Fi network: what can you do to get more insight into the people using it? Do you know which part of your venue is more crowded? Ever wondered where people spend the most of the time in your venue? Where have people been before they arrived at your venue?
Whether it is in retail, leisure, travel or manufacturing, anytime there are people interacting with a Wi-Fi environment, there is also potential to improve the user experience–that is, if you can first visualize that interaction.
With the acquisition of ThinkSmart technologies, a leading data analytics company proficient in location data mining, Cisco opens up a new customer base – that of customer oriented marketing. Cisco ThinkSmart Location Analytics solution leverages your existing WLAN infrastructure and can help you gain insight on customer behavior, giving you an opportunity for better sales and operations.
How does the Cisco+ThinkSmart Analytics work?

At Cisco Live London, Cisco unveiled Wired & Wireless convergence, along with its associated products, the Wireless LAN Controller 5760 and the Catalyst Switch 3850 with built-in Wireless Controller. While on the expo floor explaining the newly introduced ‘converged access’ to our customers, I had some interesting conversations that I thought might be cool to share with you. There may be some paraphrasing here, but if my conversation became a screenplay, it would have looked like this:
The Cisco Live! London expo show floor is throbbing with excitement, customers browse the many demos that are around the World of Solutions arena.
NAT, Wireless Controller 5760 Product Manager, stands at a demo booth with the new controller.
CUSTOMER 1 ambles over.
I heard about the converged access and it sounds very interesting. Why should I consider 5760 controller?
Do you have bandwidth hungry applications such as video / multimedia applications used by your wireless users?

There’s been a lot of buzz around our recent Cisco Unified Access Solution announcement. We understand there is also some confusion around what’s what, what’s required for Unified Access, and what the impact will be on IT.
In true Mythbuster fashion, let’s all discover why no myth is safe. Let’s review what we’ve covered in this blog series so far:
Now for our final myth to wrap up to series:
Myth 5: Efforts should focus on enabling and securing wireless, wired is dead.
PARTIALLY TRUE. It is true that wireless is being adopted at a rapid pace and IT must be conscious of this growth. However, there are many organizations that still rely on their wired infrastructure to support day-to-day activities. As pointed out in the recent Cisco Work Your Way Global Study 79% of end user respondents said they use a wired connection at work. In addition, organizations are also finding new ways to leverage the wired infrastructure to support devices such as security cameras, access systems and other non-traditional end devices. The increase in devices, both wired and wireless, are driving IT to find ways to unify and simplify how operations and the infrastructure support all devices. Cisco Unified Access does just that. It allows IT to meet this challenge by delivering common functionality across the wired and wireless network, including:
