CTS 173: WiFi Medley 001

This week’s episode is the eve of Cisco Live. Rowell & François will be headed to San Diego for a week of learning, recording, and networking with other likeminded individuals.

In this episode, we talk about various topics of Wi-Fi.

You can take a look at an example of sessions we’re looking forward to at Cisco Live.

François’ #CLUS Schedule

Captive Portals are a necessary evil. Most are still done in a way that prevents users from getting connected. Whether that’s requesting every single kind of personal information or maybe it’s a simple splash page with terms and conditions. Either way, there’s now a page which describes how different devices behave with captive portals. It was created by the Wireless Broadband Alliance and it’s a good read if you’d like to understand how a device’s behavior is to be expected with Captive Portals.

Wi-Fi 6 testing continues over at CTS headquarters. Rowell now has a Samsung S10 and an Intel AX200NGW in a Lenovo laptop. You can upgrade your laptop for a reasonable price. Rowell purchased his for $30 and it shipped from China. We’re learning whether what we’ve read from the draft is being implemented by the Wi-Fi vendors.

When it comes to capturing these frames, you have to remember to capture with another Wi-Fi 6 capable device. You’ll need to demodulate Wi-Fi 6 frames. Rowell used a Cisco C9115AX access point in sniffer mode to see what can be gathered. There’s a little caveat with these access points which we will look into further before putting something out public.

We will have more information after #CLUS.

The Wi-Fi Alliance expands with the Wi-Fi Certified Home Design which is aimed toward home builders. In a highly connected world, why not have Wi-Fi built with a new home? Builders can get educated in Wi-Fi design and have homes certified for Wi-Fi. What are your thoughts on that? Let us know in the comments.

Wi-Fi Alliances Announces Wi-Fi CERTIFIED 6

Announced at CES 2019 in Las Vegas, the Wi-Fi Alliance announces a new certification program centered around 802.11ax, or Wi-Fi 6.

Wi-Fi CERTIFIED 6 is expected to be released in the 3rd quarter of 2019.

In the announcement, Wi-Fi Alliance references the key capabilities of Wi-Fi 6 and how it will improve all Wi-Fi networks. It may be too early to tell which of the key features will be a requirement for Wi-Fi 6 certification.

The new Wi-Fi Alliance certification highlights the following 802.11ax capabilities:

  • Uplink and downlink OFDMA
  • MU-MIMO increased capability
  • Higher data rates
  • 1024-QAM
  • Target wake time (TWT)

802.11ax is not yet ratified. With the expected release of Wi-Fi CERTIFIED 6, should we expect IEEE to ratify 802.11ax October 2019?

Here’s a timeline grabbed from two locations. The first timeline came from the 802.11ax task group webpage:

As you can see, as of November 2018 there needs to be a Draft 4.0 review. The timeline hasn’t been updated since.

Here’s a WLPC 2017 presentation by Dr. Eldad Perahia showing a timeline:

It appears there may have been delays but we may get actual ratification closer to 2020.
