What a gateway does
A LoRa gateway is the bridge between low-power end devices and the network. It listens on the ISM band, demodulates many spreading factors at once, and forwards packets to a network server over a normal IP link.
Unlike a cellular base station, a gateway is not aware of individual devices. It simply receives everything within range and hands packets up; the intelligence sits in the network server.
The radio front end
The hard part is the receiver. A good gateway runs multiple demodulation paths in parallel so devices at different spreading factors can transmit at the same time without collisions being lost.
Sensitivity and antenna placement decide coverage more than transmit power. A clean 868/915 MHz front end with good filtering and a well-placed antenna will outperform a louder one with poor matching.
Backhaul and deployment
The gateway needs power and a backhaul — Ethernet, Wi-Fi, or cellular — plus a stable clock for the chirp timing. For outdoor sites, weatherproofing and a surge-protected antenna feed matter as much as the radio.
We design for the site first: what it listens to, what it talks to, and how it survives a storm. The radio is the easy part.
