Hello Nick,

Being in the industry, I've heard a lot of hubbub about LoRa and its 
perceived benefits, which seem to revolve around resistance to interference.

What worries me is that this modulation method (FM chirp) is patented 
technology. This is completely contradictory to the spirit of Amateur 
Radio, much like the inclusion of the AMBE codec into the digital voice 
modes so popular on the FM bands.

Why did the UofL team pick LoRa, rather than a more open, patent-free 
method for telemetry?

Sincerely,

--- Zach
