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 »

Today, you may be able to walk into in a convention hall, or university classroom, or baseball park and connect your mobile device. Maybe. But you’re likely competing for that connection with all the people around you. Can you join an online conversation while attending a large class at school? Can you view a live stream of the keynote address while sitting in a convention hall, or see the homerun hit while in line at the beer stand?
Today, chances are the answer is no. But that’s changing.
The reason that the answer is no, today, is that you’re sharing a finite cellular or Wi-Fi connection with all your fellow consumers in that train, convention or stadium. If you’ve got 50,000 fans, and off-the-shelf access points with “floodlight-like” unidirectional coverage areas, you’re likely sharing your one AP with 1000 other people! And if you simply put more of those APs in, the overlapping airwaves would all be competing for the same limited number of Wi-Fi channels. And when that happens, performance gets much, much worse.
But luckily, Cisco is announcing a brand new solution that addresses this issue, called Cisco Connected Stadium Wi-Fi, and it’s debuting in the Sporting Kansas City stadium. We’ve got the new Aironet 3500p access point with a very special antenna with a directional, “spotlight-like” coverage pattern. This means each AP has minimal interference with the AP next to it, and is shared by fewer fans. Everyone gets a bigger piece of the pie – and therefore more predictable levels of performance to run cool new video apps. Translation: twice as much video-viewing, iPad-carrying performance for you and me!
