--000000000000853eac06583919d6 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Dear Tsai, The patch from git diff is now attached. I summarize again the changes, please decide. 1. 30dbm (1W) of TPC condition is applied on 5470-5730. 2. Now, 320MHz bandwidth can be applied in 6GHz as WIFI 7 rolled out.
