RMHAM U Quick Tip: QMesh: A long-range, low-cost, wireless mesh network for digital voice comms

What is QMesh? It’s another MANET/wireless mesh network protocol What makes it unique Isochronous can handle streaming data like voice Self healing/self organizing Relatively low datarate (at most 10’s of Kb / Enough to support vocoded voice (700bps 1600bps) Can also carry small amounts of data (location, telemetry, etc.) Uses the LoRa Chirp Spread Spectrum (CSS) waveform Provides better Eb/N0 than “standard” modulations (FSK, PSK, etc.) Unique properties of the LoRa waveform (spread spectrum, low symbol rate) enable qmesh to work.
