Not answering your question, Bob (sorry),
but here is a link to a public access Wi-Fi Aware spec: https://www.wi-fi.org/downloads-registered-guest/Wi-Fi_Aware_Specification_v3.2.pdf/29731.
For future/anyone’s reference: many Wi-Fi
Alliance specs are available publicly, here: https://www.wi-fi.org/discover-wi-fi/specifications

Digging a bit,
I see 802.11n (2.4 and 5ghz) and 802.11ac (5ghz) are the only
PHYs.
Am I reading 802.11 right that these have FEC?

Greetings,
Over in the ASTM F38.02 discussions we are
grappling with the FAA
requiring FEC for Remote ID Broadcast (for
unmanned aircraft systems,
UAS). The final rules were finally published
Dec 28, 2020.
Work to support the FAA rules (led by ASTM) is
specifying Bluetooth 4 &
5 and WiFi NAN on FAA and EASA earlier
recommendations.
IEEE 802.11-2016 does specify FEC for some PHY.
My question is
specifically about the PHY(s) used for NAN
(which is only starting to
come out in phones to observe the messages from
the UA).
Assistance greatly appreciated!
For Bluetooth 4, we use the ASTM Authentication
Message that 'chains'
together up to 10 Broadcast frames and then our
IETF DRIP work:
https://datatracker.ietf.org/doc/draft-ietf-drip-auth/
which includes
FEC for lost frames. Can't do it for individual
ASTM messages of 1 BT4
frame.
For Bluetooth 5, there seems to be FEC built
in. Or so those working
with BT5 report.
BTW, I miss working with you all! Right now
Unmanned Aircraft is eating
up all the time I want to spend.
