All, I am pleased to present gr-lora, an open source OOT transceiver that is compatible with the LoRa PHY. Source code is available here: http://github.com/BastilleResearch/gr-lora
As an LPWAN, LoRa is designed to provide long range and low power connectivity to embedded and "Internet of Things" focused devices. It implements a chirp spread spectrum (CSS) modulation that encodes data onto a wideband signal whose frequency continuously increases or decreases. A unique design feature is that it is intended to operate on ISM bands, meaning network operators need not possess expensive spectrum licenses in order to broadly deploy wireless coverage. Since LoRa is a closed-source PHY, this implementation is based on a black box/blind signal analysis that was conducted in the absence of a specification or definitive reference documentation. More information, including my initial research results and slides from gr-lora's introductory presentation at last week's GNU Radio Conference, is archived on my personal github: https://github.com/matt-knight/research I welcome all contributions, comments, and suggestions. Thank you for reading! Best, Matt _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
