A LoRaWAN Gateway is the central hub of a long‑range, low‑power IoT network, acting as the bridge between distributed LoRa sensors and cloud applications. It receives ultra‑low‑power radio transmissions from end devices using LoRa’s Chirp Spread Spectrum modulation and forwards the data to the network server via IP‑based backhaul. This “star‑of‑stars” architecture enables kilometre‑scale coverage, massive device scalability, and high energy efficiency, making it ideal for smart cities, industrial automation, agriculture, and remote monitoring applications.
