工业网关SJ-LR02A

GPRS 3 g 以太网

•LoRaWAN半双工工作模式。•上行链路包括8个多sf LoRa通道，1个单sf LoRa通道和1个GFSK通道。•输出功率达到最大27dBm，接收灵敏度低至-141dBm@300bps。•支持LoRaWAN ClassA/B/C模式。•支持PoE IEEE 802.3 af/at。•支持10/100M以太网连接和GPRS/3G/4G连接，自动切换。•通过PoE提供100m电缆。•高可靠性工业设备，IP66设备，方便设置户外LPWAN网络。SJ-LR02A是一个基于LoRaWAN和target to LPWAN网络的物联网网关。它是IEEE 802.3 af/at兼容PD，可由PoE供电。 Both Ethernet and LTE-4G are supported to connect to the cloud server. With an integrated GPS module, the GW could support LoRaWAN Class B protocol with the synchronous clock from GPS PPS signal. • This device integrate an high performance CPU ARM Cortex-A53 core, one pcs of baseband processor SX1301, that it could support 8 multi-SF channel (SF12 to SF7), 1 single-SF channel and 1 GFSK channel. Output power could achieve to 27dBm max. Sensitivity is as low as -141dBm@300bps. With specified payload length and transmit period, one GW could support 10k nodes. •
