Note 1: It is advantageous to use the smallest channel bandwidth that can support the throughput requirements. Smaller bandwidths provide more
channels to choose and help avoid interference issues.
Note 2: Total Tx power for all streams. Max allowed Tx power depends on the regulatory domain. De-rating of -1 dBm for U.FL connector.
