+Various data-rates are selectable when configuring a channel and are inversely proportional to the theoretical range of the devices.
+
+Considerations:
+
+* Spreading Factor
+* * Each step up in Spreading Factor dobules the airtime to transmit.
+* * Each step up in Spreading Factor adds about 2.5db extra link budget.
+* Bandwidth
+* * Each doubling of the bandwidth is almost 3db less link budget.
+* Coding Rate
+* * Increasing coding rate increases reliability while decrasing data-rate.
+* * 4/5 - 1.25x overhead
+* * 4/6 - 1.5x overhead
+* * 4/7 - 1.75x overhead
+* * 4/8 - 2x overhead
