Re: [STDS-802-11] Forward Error Correction question related to FAA RemoteID Final Rules

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?

Hi Bob,

 

If I recall it correctly, Wi-Fi NAN (or Wi-Fi Aware) requires to use 11n or newer 802.11 PHYs.

You should be able to download the Wi-Fi Aware spec at:

 

Cheers,

Yong

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.
