R11e-LR8, R11e-LR9 and R11e-LR2 are concentrator Gateway cards for LoRa® technology in mini PCIe form factor based on Semtech chipset. They enables LoRa® connectivity for any MikroTik product that has mPCIe slot with connected USB lines.

A typical LoRaWAN topology consists of 3 main elements → the server, the node and the gateway.

The gateway's job is to simply forward received LoRaWAN packets that are broadcasted by the nodes (within the same supported frequency spectrum) to the server.
