I’m trying to increase the distance of my Lorawan demo system! But it have many issues!!
At the moment, my node and gateway is only work OK at about 150 meters. It seemed too wrong because lora can reach above 2-3 km!!
My setup is: AS923, max Tx power (14dbm), SF10BW125 (because rak node had to limit Dwelltime to 400ms, so it cannot get SF12 at AS923. To be honest, i don’t like this feature). The antenna i used is GSM 900Mhz/1800Mhz
About the gateway - RAK831, it is equipped with default antenna included when i bought a combo, and the gateway is placed at floor 2 of my buidding
In many case, the RSSI and SNR was not stable, and it drop to easily when i change the direction. So i think my antenna was too bad.
Anyone have tested the distance, please give me some opinions
