Advantages and Technical Analysis of Half-Duplex Gateways
What Does "Half-Duplex" Design Mean?
In LoRaWAN gateways, "half-duplex" means the gateway's receive (RX) and transmit (TX) links cannot operate simultaneously. Compared to "full-duplex" gateways (which can send and receive simultaneously), half-duplex gateways typically use a single RF transceiver channel and achieve time-division transmission/reception through fast switching.
Advantages: Simpler circuit design, significantly lower cost, and better power consumption and heat dissipation performance.
Considerations: In extreme high-density node concurrent uplink scenarios, theoretical capacity may be lower than full-duplex gateways. However, for most regional IoT applications (such as smart metering, environmental monitoring, agricultural sensing), the performance of half-duplex gateways is fully sufficient and more cost-effective.
Core Features of E870-L868/915LG12-S
-
High-Performance RF Core: Adopts the Semtech SX1302 baseband chip solution with an SX1250 front-end. Supports 8-channel parallel demodulation, capable of demodulating packets with different spreading factors (SF5-SF12) simultaneously to maximize network capacity.
-
Industrial-Grade Design and Power Supply:
-
Wide Voltage Power Supply: DC 8V ~ 28V, adapting to various industrial field power environments.
-
Wide Temperature Operation: Operating temperature range of -40°C ~ +85°C, meeting the requirements of harsh outdoor and industrial environments.
-
Compact Structure: Dimensions of only 101.6×30×63mm, supports DIN rail mounting for quick deployment in distribution boxes and cabinets.
-
Flexible Network Backhaul: Supports Ethernet (WAN port) and Wi-Fi STA mode for internet access. Some versions support 4G (note the model suffix, e.g., LG11 supports 4G, while LG12 does not). Supports intelligent multi-network switching and load balancing to ensure reliable backhaul links.
-
Comprehensive Software and Management Functions:
-
Web Management Interface: Provides an intuitive Chinese/English web interface for network configuration, LoRaWAN parameter settings, system monitoring, etc.
-
Core Configuration: Flexibly set gateway ID, server address (e.g., ChirpStack, TTN), and uplink/downlink ports (default 1700).
-
Band Settings: Supports standard regional band configuration files (e.g., EU868, US915) and advanced mode for custom channel configuration.
-
Status Monitoring: Real-time viewing of received/transmitted packet counts, channel usage, and RSSI/SNR statistical charts for easy network operation and maintenance.
-
Operation and Maintenance Functions: Supports remote firmware upgrade, scheduled restart, log viewing, and NTP time synchronization.
