[Mesh] Introduction

I'm extremely interested in SDR efforts. You guys doing custom layer 1 protocols? What frequency bands? What FPGA boards are you using? Do you have access to parallela kit? What rf frontends have you researched?  

About a million other questions,  but that's enough to start.

FNF is looking into very low power, custom layer 1/2 SDR for permament on station high altidude radio platforms. Quadcopter mesh is cute, but we are thinking more along the lines of an open source project loon. Potentially using microwave beams to power the airships, if we can't get enough power from solar. 

Copying our mailing list on this response, apology for the crosspost.
