   3. Software Overview
      The WPGR uses software that was written by Semtech to provide their customers with an Open
      Source solution for their LoRa® based products. The Picocell GW software uses a layered
      architecture which consists of the Hardware Layer “picoGW_mcu”, the Hardware Abstraction
      Layer “picoGW_hal” and the Application Layer “packet_forwarder”.

      Please refer to the following web link for access to the Software and Documentation.
      https://github.com/LoRa®‐net

      3.1    Hardware Layer – picoGW_mcu
      The “picoGW_mcu” is a low level Embedded Firmware MCU driver for the Gateway
      Concentrator PCB. It handles the power management of the SX1308 during the downlink to
      keep within the 500 mA maximum power limit of the USB Host interface. This Firmware also
      implements the USB CDC protocol to bridge commands from the Host to the SX1308 SPI
      Interface.

      3.2    Hardware Abstraction Layer – picoGW_hal
      The “picoGW_hal” is a Host Driver which runs on the Linux Host PC and provides the
      communications interface to the Concentrator PCB via the USB Serial Interface.

      3.3    Application Layer – packet_forwarder
      The “packet_forwarder” is an Application Program that runs on the Linux Host PC and
      communicates with the Picocell GW via the USB Serial Interface. The program forwards RF
      packets that are received by the Concentrator PCB to the LoRa® Server through an IP/UDP Link.
      This program also sends data from the Lora® Server to the Picocell GW that will be transmitted
      to End Nodes Devices via LoRa® RF packets.

   8. WaveFlex Picocell Gateway Radio ‐ Maintenance

      The WaveFlex LoRa® Picocell Gateway Radio is not designed to be waterproof, so it
      must never be immersed in any type of liquid. The enclosure is designed for indoor use
      only. If the Picocell GW is used outdoors it must be placed in an appropriate enclosure
      to protect it completely from the elements.

      Please refer to the “WaveFlex Gateway Base Station User’s Manual” for more details on
      the installation and operation of the complete sensor system.
