Private vs Public Network
 Private network – individually managed networks
 Network deployed for single application purpose
 Public network – Telecom/operator managed networks
 Connect multiple applications (multi-tenant) into a single network
 Consolidate fragmented wireless applications to improve ROI for entire market

LoRa Technology
 LoRa utilizes a spread spectrum based modulation
Advantages





Demodulate below noise floor – 30dB better than FSK
Better sensitivity than FSK (better Eb/No)
More robust to interference, noise, and jamming
Spreading codes orthogonal – multiples signals can occupy same channel
Tolerant to freq offsets (unlike DSSS)
