LoRa Edge™ Explored: A Deep Dive into Semtech’s LR1110 Solution
summary
Semtech’s LR1110 is a single-chip software-defined radio that combines a sub‑GHz LoRa transceiver, a 2.4 GHz Wi‑Fi sniffer and dual‑constellation GNSS (GPS + BeiDou L1), and it pairs with a cloud solver for final lat/long. It detects a usable satellite in ~0.65 s and delivers a cold fix in ~1.65 s, with sensitivity down to -141 dBm tracking. The chip ships provisioned with devEUI/keys, includes a LoRaWAN modem feature set (keepalives, file upload, auto‑rejoin), but cannot run user code and does not do Wi‑Fi 5 GHz or on‑device position computation.
