ChatterBox Data Transmission Rate
Theoretical Rate: 87,500 bytes/sec or 85.4 kb/s
Transmission Rate (bytes/sec) = (125,000 * 7 * 4/5) / 8
DATA RATE in bits/s = SYMBOL RATE times SPREADING FACTOR times CODING RATE RATIO
Actual rate is much lower, due to encryption bloating the payload, header information, and digital signature.
