We have drivers for the sub-GHz band (at86rf212 and the HUL USB support in atusb which also uses the 212). We also have support for a listen-before-talk (LBT) driver operation to make that part work with the drivers. To be honest I have not done sub-GHz testing myself here, but given the work people put into the at86rf212 support I would think it should work for some first tries. Reports welcome! regards Stefan Schmidt
