Introduction
This is low-cost LoRa gateway module which is powered by RFM96-low power long range transceiver module. The gateway can receive from any LoRa device and is designed to be fully customizable for a targeted application.Various applications are considered: water quality monitoring, cattle rustling, logistics and goods transportation.
This LoRa gateway could be qualified as "single connection" as it uses the SX1272, much like an end-device would do. However, in order to increase LoRa transmission robustness we improve the LoRa transmission with CSMA features (or so-called Listen Before Talk) and add Quality of Service guarantees with regards to radio time limitations.
