Can you Use 20/40 BSS Coexsistance in Japan?

Trying to find out if it is allowed in Japan to allow on the 2.4G radio the use of 20/40 BSS Coexistence in Japan. I have looked around on the internet but I can’t find anything that it’s allowed or if Japan only allows 20Mhz wide channels.


Hi chris.shuckerow,

I believe 40 MHz wide networks in the 2.4 GHz band can be deployed in Japan, no problem. Hopefully someone with more expertise can confirm!

Hi @chris.shuckerow,

According to Juniper Networks 40 MHz is not supported on 2.4G band in Japan.

For more detail you can consult the ARIB web site (japanese radio regulator)

I hope that could help you.
