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 1 here.
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 »

Deloitte’s 2013 Annual Holiday survey came out with some staggering statistics:
- Nearly 7 in 10 shoppers will use their smartphones and tablets to shop this holiday season.
- Nearly half of all shoppers will use social media to assist in shopping.
- 73% of shoppers will be influenced by coupons and promotional offers.
Retailers both online and in-store can no longer ignore the power of mobile technology and social media influence with shoppers. Shoppers using mobile devices inside stores are actually more likely to make a purchase when being presented with the right information. In fact, this isn’t only true for retailers, but across all industries. Whether it’s guests, visitors, patients or passengers, there’s a real opportunity for businesses to make an impression via the mobile device.
Today I am happy to announce our latest Cisco Wireless Software Release 7.6. As you may recall from Sujai Hajela’s State of Cisco WLAN blog earlier this week, Cisco’s Wireless group has been ahead of the competition with our dedication to delivering cutting edge, high performing technology to our customers.
Many features in Release 7.6 were designed specifically to enable our customers to take advantage of the latest mobile trends. Here are some of the highlights:

You’ve all heard the saying “think outside the box” when encouraging someone to be creative and come up with new ideas, new ways to do things, new ways to…..just about anything. Well, I’d like to take a small twist on the well-known saying and talk for a moment on how deploying outdoor Wi-Fi access points should be something you should be “thinking” about.
We all know that here in late 2013 almost everywhere you go, you can pull out your laptop, tablet, or smartphone and you will find Wi-Fi coverage, be it at your workplace, at a coffee shop, or in a retail store. Why is Wi-Fi coverage so pervasive in these areas? Because connecting to Wi-Fi access points and the data network behind them makes employees more productive, enables the coffee shop to be the new remote office (while selling more coffee and cakes), and provides the retail store the ability to gather analytics to better target offers for their customers.
Now let’s think about expanding this coverage to outdoors….outside the buildings. The same holds true. Providing Wi-Fi access in the surrounding outdoor locations frees up employees to take their laptops outside and enjoy a nice, sunny day while still being “online” for secure corporate email and business tools. It allows the employee to connect to that important WebEx meeting he is running late for as he pulls into the parking lot. It allows the retail store to engage with customers thru Cisco’s Connected Mobile Experiences (CMX) earlier and push offers to them as they walk in from the parking lot, perhaps pulling customers headed to nearby stores who might otherwise not have stopped in.

Cisco’s newest 802.11ac product, the Aironet 3700 Series Access Point is now orderable and shipping in the next few weeks. The AP 3700 features an integrated 11ac radio with a 4×4 architecture and Cisco’s High-Density Experience (HDX) Technology. HDX is a suite of features specific to the AP 3700 that delivers the best possible user experience, especially in high client density networks. HDX is enabled by a combination of hardware and software features on the AP 3700, features including:
- CleanAir 80 MHz – Interference detection and mitigation
- ClientLink 3.0 – RF link quality
- Smart Roam – Intelligent roaming handoff
- Turbo Performance – Performance with high client density
Aruba recently launched their 802.11ac access point, the AP-220 series, featuring a 3×3 design.
Miercom recently published a third-party evaluation of the performance between the AP 3702i and the AP-225. The report consists of a diverse range of test cases meant to gauge real-world performance of the access points. The tests include; multi-client performance, single client rate vs. range, performance in the presence of interference, and performance on reduced power. Here are some of the highlights from the report.
The AP 3700 performed very well in the multi-client performance test, thanks impart to HDX Turbo Performance. With 60 clients, the AP 3702i had a 6x performance advantage over the AP-225. The AP-225 struggled to serve all the clients and only mustered 40 Mbps total. The AP 3702i was able to transmit a healthy 236 Mbps, while maintaining fair throughput to each client.
The test consisted of 60 11ac clients, all associated to the 5 GHz radio. The clients used were 10 Dell E6430 laptops with Broadcom 4360 three spatial-stream chips, 20 Apple Macbook Air two spatial-stream laptops, and 30 Dell E6430 laptops with Intel 7260 two spatial-stream chips. Clients were setup in an open office environment surrounding the AP. Distances varied from 10’ to 50’.

The guys from No Strings Attached Show just published their podcast we sponsored featuring Jim Florwick yesterday and already the verdict is in: Jim Florwick is awesome.
For those of you who haven’t had the chance to download the podcast yet (What are you waiting for?! Download podcast) or you have a few extra minutes to scan a short blog to decide whether or not you want to download the podcast, I asked Jim what his key takeaways are when it comes to high density design.
Here are Jim Florwick’s 6 tips for HD network design (for the REAL meat, tune into the podcast):
- High density client environments are quite common with today’s users being very connected – today’s users are always connected. With planning, this can be managed quite successfully. Understand the limitations, be aware of how legacy requirements will affect the outcome, and set expectations accordingly. Efficiency is key and removing some of the blockers (legacy) first is essential.
- 802.11ac represents another quantum leap forward in technology and will eventually allow a much richer user experience. It is a transition that must be managed and balanced against your current mission requirements. Evaluate channel/bandwidth requirements carefully. Monitor the mix of client devices operating in your environment and update frequently. Read More »
