Ross wrote LORA uses chirp spread spectrum, with a signal that is ~ 125 kHz
wide (in 11 bps mode). If we have sufficient spectrum to accommodate this,
then it might be worth considering.
Actually, LORA can work at 7.5 KHZ band with a spreading factor of 12. The
present rules limit the band with < 100 KHZ I believe we could get STA to go
beyond that because the spectral flux density is so low. Or team will
explore this issue with the AIRU and the FCC to see what we can experiment
with.
