Configure OpenRoaming in Cisco SDA (part2)

So what happen at the protocol level when configuring openroaming on a Cisco SDA-network? I will explain it here in part 2 of Configure OpenRoaming in Cisco SDA

Configure OpenRoaming in Cisco SDA (part1)

With a Cisco Software Define network (SDA) many things are automated. But what if we want to configure something that’s not configurable from the DNA Center? Automation is limited till it is built to do so. In this blog article, I’m going to explain how to integrate OpenRoaming with Cisco SPACES and integrated it with Cisco SDA.

WPA3 OWE in transition mode

As part of the WPA3 Enhanced Open authentication mode, OWE was introduced. But how can we have 1 SSID compatible with OWE and non-OWE-capable clients, Let’s look at how it works.

6Ghz Packet Capture with WLANPI R4

The WLANPI is a all in one tool, to verify test and troubleshoot Wi-Fi networks. I assembled a WLANPI R4 to able to capture 6Ghz networks, because they already are deployed and we need to able to see them to fix them.

My first teaching video online

I’m teaching every 2 weeks my colleague’s things about Wi-Fi to get it more alive in the network team. This time not all colleague’s where able to join, so I recorded this session so they can play it back later.

Measure energy with IoT over Wi-Fi

HistoryIoT was born in 1999 when Kevin Ashton wanted to attach the RFID supply chain to the internet, then we have the internet of things he said. Later in 2005, the ITU said something (defined) the IoT 2005. But IoT really got ground in 2008 when the Connected objects (things) started to exceed the Human […]

Wi-Fi inside Climate cells, sure!

NPEC is a research company that finished its new research facility to do “eco-phenotyping” Within this facility, there are 5 controlled climate cells. Inside the cells, they study the effect of plants grown under different climate conditions. They asked us to install Wi-Fi for their new building (see picture below). The building looks like this […]

Dynamic Bandwidth Channel Access or DBS (Cisco)

Instead of a post, I created a short interesting video about the behavior in RF when DBS kicks in.Actually, I created this video in the first place for my internal class, to show colleagues the effect on utilization from other frequencies. But we can here also see the DBCA (Dynamic Bandwidth Channel Access ) behavior […]

WiFi is down, what change did you make?

This weekend I got a call from an educational institute. The WiFi was down. They use an SDA fabric with a fabric-enabled Cisco 9800 WLC for their wireless. The incident occurred right after they made a change from DNAC to push new radius servers to the WLC. The problem was that no client station could […]

Wi-Fi Latency requirements

Voice calls require no more than 50% of airtime (PHY) to be used ( including voice calls) on the medium. It should in basics not exceed 50%. So why is that? Because the devices that do the voice call should be on and off the medium fast. If they need to wait it may exceed […]
