Questions about using VOXL2 Max / Max2 legally in Japan

[kenjikomatsu]

Hello ModalAI Team,

We are evaluating the VOXL2 Max / Max2 platform for an indoor autonomous drone project in Japan.

I searched the forum but could not find clear information regarding compliance with Japanese radio regulations.

Could you please help clarify the following questions?

Wi-Fi
Is the Wi-Fi module used in VOXL2 Max / Max2 certified for use in Japan?
If not, is there a recommended Wi-Fi module that is compliant with Japanese radio regulations?
Country code
Is setting the country code using iw reg set JP sufficient for legal operation in Japan, or is a different Wi-Fi module required?
Remote Controller
I found a forum post explaining that the Ghost receiver can be replaced with an ELRS receiver.
Is there an officially recommended RC receiver configuration for customers in Japan?
Ethernet operation
Is it possible to configure and operate VOXL2 Max / Max2 entirely through Ethernet without using Wi-Fi after the initial setup?
Customers in Japan
Are there any customers currently using VOXL2 Max / Max2 in Japan?
If so, are there any recommended hardware configurations for Japan?

Our application is indoor autonomous flight using VIO/VSLAM, so GPS is not required.

Any advice or recommendations would be greatly appreciated.

Thank you very much.

Best regards,
