Product Info

SJ-LR02A is an IOT gateway based on LoRaWAN and target to LPWAN network. It is an IEEE 802.3 af/at compatibility PD, which could be powered by PoE. 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.
SJ-LR02A is a smart device but with high reliability, that it could work outdoor or in a complexity environment.
