World's First Fully Programmable and Open-Source Massive-MIMO Platform

The Skylark Wireless radios are based on the Lime Microsystems chip. The lead developer at Skylark is the guy who originally wrote Gnu Radio Companion and went on to write SoapySDR and Pothosflow, as well as the first (useful) driver for the LMS chips. Super smart guy at the core of a super smart team. They’re big on open source and I know firsthand that the University of Utah is using their radios. I believe that page is just old, there’s a picture on that page that shows a box that I recognize as very early Skylark equipment.

(disclaimer: I used to work at Skylark.)

I guess what frustrates me is stuff like googling "ad9361 sync" gets you: https://wiki.analog.com/resources/eval/user-guides/ad-fmcomm...

Whereas googling this about the LMS7002 seems to show you can buy a very expensive board to do this: https://www.crowdsupply.com/fairwaves/xync#synchronization-p...

Also, on the limesdr too: https://discourse.myriadrf.org/t/synchronize-two-limesdr/171...

it looks like you can chain reference clocks to get a fixed offset? https://wiki.myriadrf.org/LimeSDR-USB_hardware_description and then get some external device to do reset on the digital side for sync.

Independently, I'd love to know more about Skylark's SDR product and play with it.
