Part 97 FCC regulations

[Ted-K7LRF]

Is there a way to activate channels 0 (2.407 GHz),-1 (2.402 GHz), and -2 (2.397 GHz) under Part 97 of the FCC regulations?

Thanks for the reply, but what I'm looking for is how to program the ESP32 to work on these channels.

I know, it was for the benefit of other readers. Hopefully someone else can answer, but it is probably not supported.

hi

i think i can not help you in your base question,
( warning:
Using professional grade hardware or modified consumer grade hardware it is possible to operate on 802.11b/g hardware on channels that are effectively "0" at 2.407 GHz, "−1" at 2.402 GHz, and "−2" at 2.397 GHz. Using these channels allows amateur operators to move away from unlicensed Part 15 operators but may interfere with amateur radio satellite downlinks near 2.400 GHz and 2.401 GHz.
but i can link you to the most theme to this.
)

i think it is not knowed, public - not wanted to publictae it -
so perhabs possible not possible, .

causes
this papers helps you on your further ways and info to find answeres for you

- FCC-ID 2AC7Z-ESP32

- ESP32 Faqs

SCAN example by default
it is 1-11 ( active scans )
it is 12-13 ( passive scans )

( no 0, -1, -2 )


please read this too, it is for esp8266
^btw i miss this docu for an esp32^
but it is named the same things you are talking about in channels.
- ESP8266 Wi-Fi Channel Selection guidelines

it is 1-14 ( 14 is not supported in japan )
( no 0, -1, -2 )


also please have a look to the tools if you not know about them

This guide demonstrates how to run an RF related performance test
and certification test using an RF tester to check an
ESP32 / ESP8266 based product, either functioning as a standalone
controller or an integrated part of MCU.

i think 0, -1, -2 is not possible publicated or not wanted to publicated detailed,

if there is a possible doing it would be nice if espressifer's can show the way
or give an better detailed answere and why it is not possible

have a note to antenna design rules on 0, -1, -2 and fine tune.

hope this helps a little.

best wishes
