@lupyuen Is it the same as that of Semtech lora?
@krag Says here that "All features of the LoRa physical-layer modulation scheme are described in various patents and blog posts"

@lupyuen thanks a lot....this can help in implementation of localization of lora nodes without semtech license.
@lupyuen that's really useful.... I thought that PHY layer is proprietary
