LoRa - Long Range wireless data telemetry

Hello Lausanne! For our first meetup, we'll be looking into LoRa, a revolutionary new way to communicate for IoT devices.

LoRa is Long Range wireless data telemetry and relates to a radical VHF/UHF 2-way wireless spread spectrum data modulation approach that has recently been developed by Semtech.

The technology is proprietary, but it appears to use some sort of "simpler" CSS (Chirp Spread Spectrum) pulsed FM "sweeping frequency" modulation rather than DSSS (Direct Sequence SS) or FHSS (Frequency Hopping SS).

LoRa offers a 20dB link budget advantage compared to existing solutions, which significantly extends the range of any application while delivering the lowest current consumption to maximize battery life.
