G’day Ben I will start by noticing that you gave me a gender reassignment. Excellent, Andrew one day and Andrea the next!
J That aside, I will say that I was a little loose in my language. When I mentioned the “only game in town” I was mainly focusing on WLAN-like applications. Of course, there are many other systems using the unlicensed bands, and over the years our efforts, market drivers and a little bit of luck have meant that either Wi-Fi and these systems coexist reasonably well
in these bands or they have generally avoided each other in these bands. There are a small number of systems where neither option is reasonably possible, and these systems have tended to go elsewhere (but not always). By focusing on WLAN, I was not commenting on the need (or otherwise) of Wi-Fi and NR-U to coexist with other systems. Rather, I was highlighting that Wi-F and NR-U need to coexist with each other as a starting
point, and that IEEE 802.11 Coex SC is where this discussion is taking place within IEEE 802. IEEE 802.19 (and IEEEE 802.18) are the forums where other coexistence combinations should continue to be discussed. Hope that helps mitigate your concerns Andrew From: Benjamin A.

Hi Andrea, Thank you for the information and outreach, and specifically to those with interests in the 6 GHz band. I read this to indicate that you wish to include coexistence with all services, including other 802 wireless,
in the scope of the study group - which is a great idea IMO. If that's the wrong read, please correct. I think you hit a key attitude issue with your "only game in town"; depending on what "town" you mean, in most of the world this has not been a true statement for decades. There are in fact many license exempt
uses besides WiFi, and many billions of of those licensed exempt device are based upon 802 standards other than 802.11. WiFi provides a visible label which consumers recognize, which shows up on the outside of the box. There are 802 wireless standards
enabling operation in a diverse range devices. 802.15.4 in particular is used in a dizzying array of applications where high bits/sec is not the critical performance metric, which includes some rapidly growing application areas such as secure entry. Perhaps
the reason many people feel WiFi is the "only game in town" is because in 802 we've taken coexistence seriously and consider the impacts of new standards on the operation of other 802 standards. Seriously - good coexistence is an factor in market success.
One of those not noticed things until it's noticed: when you do it right it's not noticed, when we don't, being noticed is a bad thing. We've seen this suppressing 802.11 use in applications where it's feared to be disruptive e.g. 900 MHz 11ah. It really
is in "our" best interests to consider how to coexist! Preaching to the choir I suppose, consider it an hearty endorsement of your efforts! If there's an argument in there that helps you, better still.
I may be able to provide a short presentation on 6 GHz coexistence at the November meeting, depending on when the SC meets. I've not seen the consolidated schedule yet - when does your SC meet? I promise
to keep it positive. Thanks again, G'day Ben On 10/11/2018 11:01 PM, Andrew Myles (amyles) wrote:
