There is no turning back from the mobile trend. With more devices comes the insatiable hunger for bandwidth. After devices are connected to the network, IT must make sure each is secured and provisioned. Creativity is needed to handle these high-density environments and enforce proper policies for mobile security, while juggling other responsibilities for the business. That complexity can be a huge headache. IT needs tools that can help make the whole process simple and fast.
Enter Cisco’s secure enterprise mobility solutions. Cisco’s 802.11ac (the latest Wi-Fi standard that enables more devices and bandwidth), Cisco Identity Services Engine (ISE), and Cisco TrustSec solutions join forces to simplify the high-density, secure mobility experience.
Join us for an engaging webcast on March 5 and learn how this combined Cisco solution can relieve your mobile device management and security headaches. Hear how Erickson Living, a trusted name in retirement communities known for innovative approaches to supporting resident needs, relied on this Cisco solution to provide high-quality, secure connectivity and a simple user experience.
Register today to learn how Erickson was able to level up to 802.11ac with heavy considerations for mobile security and how Cisco provided the tools to easily manage always-on, secure wireless access.

If you are an Enterprise IT Manager, this is a question that you must ask yourself if you are considering deploying 802.11ac for your enterprise wireless network. 802.11ac has some great benefits such as wirelike speed and being able to handle a high concentration of clients. However, there is more to consider when deploying 802.11ac. For instance, how do I handle RF interference now that 802.11ac support 80MHz channels? Will legacy devices such as 802.11g/a/n allow me to achieve the best performance that 802.11ac advertises? How can I ensure that my users get the best wireless performance when they roam across a building? And lastly, as more clients join the network, is my performance going to suffer? These are all valid concerns and are something that Cisco addresses with HDX. HDX is High Density Experience and is part of Cisco’s 802.11ac solution. We just wrapped up a 4 part blog series on HDX where we answer these questions:
- For Interference Mitigation, we have CleanAir for 80MHz Channels
- Getting the best performance out of your network even with legacy clients, we have ClientLink 3.0 Read More »

With any new technology comes a new set of obstacles to overcome. 802.11ac is no exception. Last week we talked about CleanAir for 802.11ac and why spectrum intelligence still matters. Another challenge is scalability. In this post I will give you some details on new HDX feature, Turbo Performance, which allows the AP 3700 overcome common scaling issues to scale amazingly well.
What’s Different with 802.11ac?
802.11ac means higher data rates, which means more packets per second (PPS). There are three reasons for more PPS with 11ac: wider channels, increased modulation and increased aggregation. Channel width doubled to 80 MHz, modulation increased from 64 QAM to 256 QAM, and aggregation increased from 64k to 1MB!
With 802.11n, an AP might have had to push 30,000 1500 byte packets per second through the APs data plane. Today with 802.11ac that could now be 75,000+ PPS. More PPS means more load on the APs CPU, so to really keep up with the demands of 802.11ac, we needed to go back to the drawing board. Read More »

CleanAir for 802.11ac: Why Spectrum Intelligence Still Matters
In wireless networking and communications, as with life, nothing good comes for free. It’s well known that the primary feature of the new IEEE 802.11ac amendment is support for an 80 MHz-wide channel. The benefit of an 80 MHz channel is the potential to double usable throughput in comparison to that of 802.11n using a 40 MHz wide channel.
However, what is less well known is that a wider RF channel is also more susceptible to interference. In other words, 802.11ac devices “hear more” than 802.11n devices, primarily due to the wider channel support. It should be noted that this is not a flaw in the 802.11ac amendment, it’s simply basic communications theory.
Nevertheless, there is far more to building an 802.11ac access point than simply meeting the standard. Not all 802.11ac access points perform equally without interference. But more importantly, not all 802.11ac access points perform well in the presence of interference.
Furthermore, there is far more to deploying High Density wireless LANs than only considering the performance of individual access points. Read More »

A new year means new users and new devices. More devices means more network crowding. Mobile users demand bandwidth and speed, while the network is increasingly overwhelmed by the sheer number of devices. The networks of today and tomorrow have to be ready for high client density environments.
That’s why we’ve developed the Cisco High Density Experience (HDX). I announced HDX in a blog last October with a high level look at Cisco’s answer to handling high client density environments. Each feature in the HDX solution was designed specifically to alleviate the introduction of more clients, more bandwidth hungry applications to provide an unparalleled user experience.
Starting tomorrow we’ll kick off an HDX blog series to dive deep into the four key features that come with HDX:
- January 8: CleanAir
- January 13: Turbo Performance
- January 27: ClientLink 3.0
- February 10: Optimized Roaming
