* 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.
** Throughput of a wireless link depends on many environmental parameters. Here the bench measurement results are shown to
give an indication of the real life performance of Doodle Labs modules. These results are lower than the theoretical values
published in most of the literature. They do not include distance related derating.
