DRAGINO Indoor Gateway LG308N-868-E met 4G/LTE

When a LoRaWAN gateway delivers -139dBm sensitivity and a 4G/LTE backup link, it's built for serious IoT deployments. The Dragino LG308N-868-E packs the Semtech SX1302 concentrator, a robust MIPS processor, and triple connectivity into a compact indoor enclosure—making it a top choice for industrial sensing, smart agriculture, and remote monitoring.

Overview

The LG308N-868-E is an EU868 LoRaWAN gateway with eight uplink channels and one downlink channel. It connects to the internet via 100Mbps Ethernet, 2.4GHz Wi-Fi, or the built-in 4G/LTE module (Quectel EC25-E). Running OpenWrt Linux, it offers flexible management through a web GUI or SSH. The unit supports LoRaWAN classes A, B, and C, and is ready for both small-scale pilots and full production networks.

What stands out

• High-performance SX1302 digital baseband chip for reliable LoRa demodulation
• Integrated 4G/LTE ensures connectivity even where wired and Wi-Fi fail
• Class A/B/C support for comprehensive end-device compatibility
• OpenWrt-based system with customisable packet forwarder and management
• Internal LoRa and Wi-Fi antennas, plus an SMA port for an external 4G antenna
