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 »

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
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.

Hey folks, I’m back in the blogosphere to make a super exciting announcement.
The Cisco Aironet 3600 Series Access Point with its purpose built best-in-class Wireless performance, industry’s first and only Enterprise Class AP to support 802.11n with 4x4 MIMO architecture, and signature modular design was launched in January 2012 at Cisco Live! London. Cisco was first to market with an 802.11ac wave 1 solution and first to be published with WiFi Alliance certification. Just 18 months since launching, the flagship 3600 AP has now surpassed the ONE MILLION mark in units shipped!
We designed the access point with modular architecture in mind to give our customers more flexibility for upcoming technological innovations in the wireless space. Since the initial launch, we have announced three exciting modules tailored to help our customers meet their wireless needs: Wireless Security and Spectrum Intelligence, 3G Small Cell, and most recently 802.11ac Wave 1. The modules have been extremely successful, having deployed 40K units of the .11ac module and 10K units of the Wireless Security and Spectrum Intelligence module, which speaks volumes about the versatility of the 3600 Access Point.

Curious about how to use 802.11ac in Higher Education and other high density wireless environments?
Tomorrow, July 24, we are hosting another 802.11ac webinar, this one focused on Higher Education. We will feature Mark Denny, Cisco Product Manager from the Enterprise Mobility Group, who will provide an overview of 802.11ac, discuss the benefits of 802.11ac and provide a summary of Cisco’s 802.11ac Solutions. We will then have Greg Sawyer, the Manager of Communication Services at the University of New South Wales in Sydney Australia, discuss his experience with 802.11ac, the reason why he is deploying 802.11ac and the benefits he expects from this emerging technology.
The webinar is tomorrow, Wednesday, July 24th @ 3PM PDT. Here is the registration link. If you miss it, we will have it available on demand here shortly after. Also, if you missed last week’s 802.11ac Webinar for Healthcare, it is available in the dropdown on demand here.

With any new wireless technology, much of what is initially written in the first year is usually focused around the bits and bytes and the speeds and feeds of the technology. This is true for 802.11ac where any Google search will yield a plethora of articles on the potential of Gigabit wireless or that it runs on the 5GHz band and could have up to 8 spatial streams. However, the conversations must start moving towards discussing how the technology can be used in practical situations. In the case of our 802.11ac Module for the 3600, we feel very strongly that it is necessary to not only talk about the speeds and feeds of 802.11ac, but also show how a customer plans to use 802.11ac.
That’s why at our popular presentation at Cisco Live! Orlando, we first discussed the 802.11ac Standard, Cisco’s 802.11ac solution and how it can be used in various networks, and then invited representatives from Methodist Hospital in Houston, TX to discuss their experience to date with 802.11ac.
