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.

Hi, I'm Marc Juul. I'm excited about decentralized and heterarchical structures, both in the form of networks and in systems for organization. I co-founded two hackerspaces (sudo room and labitat) and two biohacking groups (biologigaragen and counter culture labs). I have skills in the fields of network programming, web programming, digital electronics and synthetic biology (not yet sure how that last one will be relevant to the mesh but I'm sure we'll find a way!). I'm very interested in crypto, and its application in mesh networks.

I've been wanting to learn about radio, both the details of wifi and the fundamentals of radio transmitters and receivers, for several years and I'm delighted to have the time to really dig into this field.

I want to take this chance to announce that we also have a small sub-group within the mesh group that is playing with software defined radios and designing and building our own radios for digital communications. If you're interested in hanging out and poking at that kind of stuff then speak up!

Personally, I'd like to see us not just build a successful wifi mesh that is run for and by the local community, but also begin improving on the state of the art of mesh software and hardware.
