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. The system’s SNR is higher at smaller Channel Bandwidths and Range is longer.
Note 2 Max allowed Tx power depends on the regulatory domain
