SenseCore HT-M7603 Indoor LoRaWAN Gateway
The SenseCore HT-M7603 is a compact, affordable indoor LoRaWAN gateway designed to bridge LoRa wireless sensor networks with IP-based backhaul. Its wall-mountable, space-efficient form factor and support for both Wi-Fi and Ethernet backhaul make it ideal for indoor IoT, smart building, utility, or sensor-network installations. With support for standard LoRaWAN 1.0.2 (Class A & Class C) — as well as custom MQTT mode — the HT-M7603 offers flexibility for both public LoRa networks and private, self-hosted MQTT-based deployments under the SenseCore platform. wiki.heltec.org+2s.heltec.cn+2
