Miercom: Cisco Aironet AP3702i

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.

Multi-Client Performance

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’.

Deploying, Testing, and Tuning 802.11ac

By now you’ve probably heard quite a bit about the newest generation of Wi-Fi, 802.11ac.  I’ll save you the gory details, just know it’s about 3x faster than 802.11n and will help to improve the capacity of your network. Jameson Blandford and I were recently guests on the No Strings Attached Show podcast with Blake Krone and Samuel Clements (Click to listen to the podcast).

I wanted to follow up the podcast with a blog to go over considerations for deploying, testing, and tuning 802.11ac.

Considerations for deploying 802.11ac

Switching infrastructure

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.

Robot Soccer? Staying Connected at Bowdoin College

October 15, 2013 at 2:14 pm PST

As our team has prepared for Educause 2013 this week, we have been talking a lot about technology in higher education and how it’s impacting colleges, universities, students and staff. Of course, robot soccer was not the first thing that came to mind, but it’s a great example of how different technologies are changing education forever.

Bowdoin College, which you may remember from last year’s #1 Most Connected College, is one of my favorite case studies because it points out that people have to TRUST technology for it to really be effective. Trust is a big word, really – I know I’m not the only person who is a little gun shy when I think about updating my phone to a new software version. So, when a professor has a class full of students and says “let’s all stream this video right now”, it’s important that it actually works – or professors risk losing student attention, losing time and facing maximum frustration levels.

Top 7 Facts to Know about Cisco HD Experience Technology

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.

BYOD with Flair – Cisco Customer Vitra AG has Designs on Manufacturing.

September 13, 2013 at 9:20 am PST

 

Having just moved into a new house, my wife and I are looking to see how all our old furniture can be re-used -- with her eye on the best design (she’s a designer by trade), and my eye on cost. We’ll end up somewhere in the middle I expect, slightly geared towards ‘design’ if past experience is anything to go by!

An example of Vitra design -- the VitraHaus

Swiss furniture manufacturer Vitra pulls off both objectives -- providing customers with great design, AND managing to reduce cost in the organization, How? With Cisco of course!

Take a visit across the Swiss border into Germany and you can visit to the VitraHaus location, its flagship store. Visiting Vitrahaus is like taking a trip through design history, but it also offers the opportunity to encounter the work of leading contemporary designers. Furnishings and objects from the Vitra Home Collection are arranged in a variety of settings for both living and working.

Communications and collaboration are central to bringing these concepts to life. Vitra has been partnering with Cisco for over a decade, evolving its IT infrastructure and expanding wireless LAN deployments. The biggest concentration of wireless access points, more than 70, is at Weil am Rhein. The latest stage of that IT strategy intends to make wireless a key enabler for business transformation.

“Improving guest Wi-Fi access was very important,” says Marco Gersbacher, head of IT infrastructure services at Vitra, “while we also wanted to make sure the business was fully prepared for bring-your-own-device.

Although Vitra had no formal bring-your-own-device (BYOD) policy, a growing number of employees were using personal smartphones and tablets alongside company laptops in the workplace.

Vitra Style - style is pervasive in all that they do.

Vitra Style -- style is pervasive in all that they do.

This trend created problems with device recognition and password reset requests. Certain devices could connect only over the wired network, others just to Wi-Fi, and some not at all. So, a robust BYOD framework was a strategic priority. Without visibility of devices, however, the company was unable to guarantee network performance and security.

A validated Cisco® Borderless Network design has helped enable Vitra unify access across all network domains: wired, wireless, and VPN. The solution was installed by NextiraOne and includes the following components: Read More »
