Boost LoRaWAN: overcome limits
summary
Claims that coverage is the bottleneck not capacity supported by simulations and field numbers: densifying to about four gateways per km² reduces non‑connected devices and yields roughly 500 devices per gateway. Repetition (NBTrans up to 15) gives diversity — optimal NBTrans=4 in static networks, ~10 dB margin for ~6 dB energy cost. Relay prototypes work but double end‑device energy and hit duty‑cycle limits (~4–5k frames/day per relay). Signal Channel Hub and network discovery/drive‑by features aim to extend coverage.
