6 Tips for High Density Network Design

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):

  1. 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.
  2. 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.

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.

IoE: Dead or Alive on Wireless

September 12, 2013 at 2:51 am PST

When we examine the average wireless client on a network today, we see a few options. There is the smartphone, the tablet, or the laptop. Even the Apple TV and Roku are often based off of similar technology and chipsets. All of these devices connect to a wide range of services, often consuming large amounts of bandwidth: we stream music while we browse; we video chat with friends, family, and coworkers across the globe; catch up on our favorite shows or sports teams. Occasionally, we do all of these things at the same time.

Our current wireless networks are built to handle this type of traffic. With 802.11AC, it is clear that we will be ready for anything that our standard client will encounter in the near future.  But what happens when the standard client model is broken?  The increasing shift to an Internet of Everything (IoE) forces us to face this question about the future of wireless clients.

There are lots IoE devices already on the market, and the next couple of years will see developments not that dissimilar from those during the “internet revolution” of the late 90′s. Finally, the average user will have the access and the ability to afford the smart homes we have been dreaming of for the past thirty-plus years. Read More »

[Cisco Cartoon Catalyst Series] Prime Your Network for the Rise of the Devices

It’s a nightmare out there. School districts’ wireless networks now have to support teachers, students, and staff – all touting desktops, tablets, smartphones, and/or laptops.  For some in IT, knowing who is accessing what using what on the network (a confusing statement itself) could very well be cosmic chaos; for others, it is simply a black hole of the unknown.
