We Made It To Episode 100!

100th episode giveaway

I never thought I’d make it to episode 100 of this podcast. The first episode was published in August of 2015. The reason for starting the podcast was to learn more about Wi-Fi. To get into the community and help others who were getting started.

At the time I was an IT Manager with a strong interest in Wi-Fi. I didn’t have many friends of colleagues specializing in Wi-Fi which led to this podcast being born.

At first it was difficult to produce an episode each week. It actually is still difficult but it comes natural now. Especially with François joining as a co-host.

François and I have known each other through Twitter. I’m not sure how we even connected but a fun fact is that we didn’t meet in person until October of 2017. We met in Toronto, Canada where our families had dinner together. With the addition of François the quality of the podcast has increased. So I thank him for all this efforts!

We both record at home and for me it is in my garage. We do it when we have spare time and often have enough time just to hit the publish button for the week 😉

CTS has had only one sponsor so far, Metageek, who help fund the podcast expenses. We greatly appreciate them as they are a product we use regularly.

What We’ve Learned with Podcasting

It’s difficult to release one episode per week! With the both of us working full time it’s easy to get busy. After a full days’ work we spend time with our families so we often have to juggle time to record. On top of that, there is a three hour difference between us. I am in California and François is near Toronto, Canada.

When it comes to recording we have to be very efficient. There is hardly any editing that goes into the recordings unless we really need to edit. We’re not audio professionals but we do our best to get the best audio quality recorded.

What equipment & software do we use?

Memorable Episodes

Our first Round Table was interesting to record. Getting a group of Wi-Fi professionals together can lead to all sorts of conversations. It’s also a challenge to keep those conversations on topic for a podcast.

Devin Akin’s recording on channel widths was highly informative and educational. I’d say we all learned a thing or too on using wider channels and also being aware of OBSS.

Learning how Ubiquiti used Andrew’s Capacity Planner to equip the FedEx Forum with their UniFi APs was inspiring. We enjoy hearing how others have solved an issue, encountered challenges, and deployed Wi-Fi.

Mist is another memorable episode because it’s what is new in our industry. They’ve included some eye opening metrics to our Wi-Fi systems which should help us all lower the amount of time to solve Wi-Fi issues.

What are the top 5 episodes?

What’s Next?

We want to increase the production quality of the podcast. We continue to work on the audio quality but we also want to improve the podcast overall. We will put more focus on the show notes so they can be just as valuable as the audio episodes. François will begin recording in French! Of course we will continue to bring in interviews as there are so many people to hear from. Even those who may not be active on social media.

Another improvement we will be focusing on is our newsletter. If you haven’t already, sign up for notification of published episodes, get industry news through This Week in Wireless, and more. There will be more relevant content communicated by François and I through the newsletter.

CTS 086: Capacity Planner, Ubiquiti and FedEx Forum

Let’s welcome Andrew von Nagy of Revolution WiFi and Capacity Planner, Brandon Gilles of Ubiquiti, and Jeff Hansen also from Ubiquiti. They join us on this episode to inform us about the collaboration of Ubiquiti with Andrew’s latest version of Capacity Planner. Ubiquiti also goes into details about the FedEx Forum UniFi deployment to fill both high density and capacity.

Andrew von Nagy’s Capacity Planner was released two years ago to the community. It’s goal is to provide education on capacity topics, help administrators improve and build better wireless networks, and help move the industry forward. For version 2 of the capacity planner, Andrew has partnered with Ubiquiti.

The latest features and enhancements to Capacity Planner version 2 include:

  • Analysis graphs
  • Data to understand how capacity is used and where improvements can be made
  • Mesh planning
  • Improved visibility into AP load
  • 802.11ac Wave 2 and Dual 5 GHz deployment support (excluding MU-MIMO)

So why did Ubiquiti decide to get involved with the capacity planner?

  • Education of community
  • Customer reach of Ubiquiti
  • Future deployment of a web-based version

Full capacity at the FedEx Forum

The Capacity Planner was also used as a sanity check for the deployment of UniFi APs at the FedEx Forum. Used for determining how many access points were required to maintain capacity, determine what their minimum rates were going to be and what utilization would look like.

Within the FedEx Forum, capacity and frequency reuse were tightly coupled together. In the end, 86 APs were servicing users in the main bowl area. A large matrix spreadsheet was used to determine their channel plan and site surveys were used to see which areas heard which APs. All 5 GHz channels were used and there was close to reuse of 1.8x.

An external antenna pointed downwards at the FedEx Forum

The biggest attendance at FedEx Forum saw at peak, 4000 users using about 1 Gbps/sec. Also at peak. The geometry of the bowl created a lot of on-channel noise.

Taking QoS and load balancing into consideration, airtime fairness saw a good improvement. Devices were getting about 50 Mbps of throughput without limitation. Eventually, devices were limited to 10 Mbps. Load Balancing played a role as the team revealed an excess of 200 users on a single AP. Most of the clients were actually 1×1 and 2×2 clients. UniFi features a soft and hard load balancing. An AP will reject an association to try and force a client to another AP but has intelligence built-in if a client continues to join the same BSSID.

In the future, there are plans to integrate Capacity Planner within the UniFi user interface. Listen in on the episode to hear much more!
