Editor’s Note: This is the second of a four-part deep dive series into High Density Experience (HDX), Cisco’s latest solution suite designed for high density environments and next-generation wireless technologies. For more on Cisco HDX, visit www.cisco.com/go/80211ac. Read part 1here.
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 »
Takeaway: The Cisco Enterprise Mobility group has stayed ahead of the competition by staying innovative and cutting edge while delivering quality, high performing products and solutions, while displaying thought leadership on major technological trends such as 802.11ac and location-based services. We use this mobility blog as a platform to deliver information straight to wireless fans and readers. Here are the top 10 most read posts in 2013.
If it seems as if the roles of chief information officer (CIO) and chief diversity officer (CDO) rarely overlap, think again. In today’s hypercompetitive — and hyperconnected — global marketplace, inclusion, collaboration, and technology are merging as essential drivers of innovation and business success. And the relationship between the CIO and CDO may never be the same.
Indeed, fostering a policy of inclusion and diversity in your organization isn’t just the right thing to do; increasingly, it is also the profitable thing to do. And, it’s a clear business imperative, since great ideas come from all corners — and levels — of the organization.
In a Cisco survey of 7,500 companies, 93 percent of enterprises with a formal policy of inclusion reported that their collaboration technology investments outperformed their business value expectations. That’s just one example of the inclusion/diversity/value equation at work.
The first question you’ll want to ask yourself, is, if your switching infrastructure can handle 11ac? The answer probably is, yes. The things to consider are the port speed and power-over-Ethernet (PoE) capabilities. You’ll want the access point to have a gigabit uplink to the switch. Each 11ac access point could potentially dump several hundred megabits per second of traffic onto your wired network. It’s also not a bad idea to have 10 Gig uplinks on your access switches to distribution or your core. If you have even just a couple access points on a single access switch, you may quickly find yourself wishing you had 10 Gig uplinks.
Next you’ll need to consider how you will power the access points. If you are like the majority of our customers, you will use PoE from your switches. While 11ac access points require 802.3at (PoE+) for full functionality, the Aironet 3700 will run happily on standard 802.3af PoE. In fact, it remains 3 spatial-streams on both radios, so performance does not suffer because you have a PoE infrastructure.
Since launching Connected Mobile Experiences (CMX) – Cisco’s innovative solution that turns the network into a platform for delivering location-aware, in-venue services – customers have been intrigued. However, CMX could not exist without the Cisco Mobility Services Engine (MSE), a location-aware network appliance to provide location-aware capabilities as well as deep wireless security.
Before I get into the new pricing details, here’s a quick recap of what the MSE can do:
The MSE is a network appliance that takes your wireless network and turns into a platform for delivering cool and innovative location-based services that provide unique business value through online, onsite and social analytics. For example, you can now leverage your wireless network to see how many customers are visiting your store? Are they new or repeat customers? Are long wait times at checkout hurting my business? With the MSE, organizations can even communicate directly with visitors in their venue through their mobile devices. You can now provide wayfinding (indoor GPS) and push relevant content such as offers or coupons directly to your visitors, which in turn can drive revenue gains for the venue.
The MSE does more than location based services – it also has a rich set of network security tools (known collectively as wIPS – wireless intrusion prevention system) that help protect the network from all kinds of attacks. The MSE can not only tell you that there is an attack taking place, but it will tell you which type of attack (“honeypot”), where the attack is coming from, and will also enable the network fight back against the attack (“flood the attacking device with traffic making it impossible for him to do anything”).
We wanted to make this great functionality more accessible and affordable for our customers, so I am happy to announce that we are offering a new pricing promotion for MSE licenses starting now until April 2014.
