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. Read part 2 here.
The 802.11ac wireless networking standard is the most recent introduction by the IEEE (now ratified), and is rapidly becoming more accepted and reliable industry standard. The good news is that the client and vendor adoption rate for 802.11ac is growing at a much higher pace as compared to when 802.11n was introduced back in 2009. There has been an accelerated growth seen with the mobile and laptop devices entering the wireless market embedded with an 802.11ac WiFi chipset. Unlike in the past, laptop, smartphone and tablet manufacturers are now acknowledging the fact that staying up to date with the latest Wi-Fi standards is as important for the bandwidth hungry users as having a better camera or a higher resolution display.
With the launch of the new 802.11ac AP 3700, Cisco introduces the Cisco HDX (High Density Experience) Technology. Cisco HDX is a suite of solutions aimed towards augmenting the higher performance, more speed and better client connectivity that 802.11ac standard delivers today.
ClientLink 3.0 features as an integral part of Cisco HDX technology designed to resolve the complexities that comes along with the new BYOD trend driving the high proliferation of 802.11ac capable devices.
So what is ClientLink 3.0 technology and how does it work?
ClientLink 3.0 is a Cisco patented 802.11ac/n/a/g beamforming technology Read More »
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 4x4 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 3x3 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’.
Last week, we announced at Interop-NY our newest Indoor Access Point, the Aironet 3700 Series. This access Point includes an integrated 802.11ac radio and is the first and only access point to support a 4x4 MIMO on 802.11ac. This latest Wi-Fi Standard will provide wireless networks better performance and coverage, and address the demand for client access including 802.11ac enabled clients. Whether you are in Higher Education, K-12, Healthcare, Manufacturing, Retail or other verticals, we are seeing our customers across industries face the same challenges: more users coming onto the network, more users bringing more devices, more devices that are only wireless connectivity (no Ethernet port), more security, OS and application updates on each of those devices. All this drives the larger problem of high density.
Enter the Cisco HD Experience Technology. Available on the new Aironet 3700 Series Access Points, the Cisco High Density Experience or “HD Experience” Technology is a suite of solutions serving up a feature set designed specifically to alleviate the introduction of more clients, bandwidth hungry applications and high density network strain in order to provide an unparalleled user experience.
Here are the top 7 facts to know about Cisco HD Experience Technology:
1. HD Experience Technology is a suite of solutions only available on the AP3700 that helps OPTIMIZE performance, mitigation, scalability and roaming for High Client Density networks
2. HD Experience is a hardware-based solution on a WiFi chipset designed BY and FOR CISCO. This is *not* software features based on merchant silicon WiFi chipset. HD Experience includes…
3. CleanAir 80 MHz, where Cisco fundamentally retooled the award-winning CleanAir technology to provide the same level of granularity and accuracy of RF interference detection and mitigation across 802.11ac’s 80 MHz bandwidth…but it also detects and mitigates for 802.11a/b/g/n clients as well.

Last week Apple dominated tech headlines when it announced details of the iPhone 5. With its release today, thousands of fans will line up across the globe to be the first to try the new smartphone.
There have been a number of iPhone improvements, but the one I find significant is the fact that the iPhone 5 will have dual band Wi-Fi. This means that in addition to supporting the 2.4GHz band, it will now support the 5GHz band. Why is this significant? Well, the iPhone joins a number of other smartphone vendors who now have products capable of operating in both the 802.11b/g/n (2.4GHz) and 802,11a/n (5GHz) Wi-Fi bands. Other vendors that stack up include Samsung’s Galaxy S III and HTC’s One X.
Why is this 5GHz important? There is certainly nothing wrong with the 2.4GHz band. Both bands are unlicensed in most regions of the world. However, with the proliferation of devices due to the growing BYOD trend, the 2.4GHz band is getting real crowded. Remember: the 2.4GHz band only has 3 non-overlapping channels available. Think about it: all these devices like smartphones, laptops, tablets, and access points are competing for the available bandwidth while interference increases. In short, the 2.4GHz band just doesn’t have enough capacity for all these competing devices.
We released our latest in the Fundamentals series earlier this month and it is trending quite well. The 802.11ac standard sounds like a step backwards alphabetically…but it will soon be an incredible step forward forward for WiFi once it is ratified by the IEEE. Watch this latest fundamentals to get comfortable with the truth. 802.11n is still your best bet for 2012 and into 2013 as we continue to partner on the standards process but the future is bright indeed!
