 Starting from September 2016, Saint-Joseph University of Beirut (USJ) will be deploying the first academic [[http://www.semtech.com/wireless-rf/internet-of-things/what_is_lora.html | LoRa]] network in Lebanon. The network will support monitoring of micro-climate conditions in vineyards. Here below you can find a detailed description of the experimental platform implementing an end-to-end LoRaWAN solution.

-==== -. Single Channel Packet Forwarder ====
+==== -. Single Channel Gateway ====
+The single channel gateway includes a LoRa transmission module (Dragino Shield) connected to a Raspberry Pi (2 or 3) as shown in Figure 1. Communication between the two modules is done over an SPI interface.

+In order to assemble the gateway, start by making the wire connections: the connection pins are identified in Figures 2 and 3.

+[{{ :schema-pins-pi3.png?direct&300 |Figure 3. Raspberry pi 3 pins}}]
+Connect the Raspberry Pi to the Internet and install the packet forwarding software. The source code of the single channel packet forwarder is available on: [[https://github.com/samerlahoud/single_chan_pkt_fwd]]. In order to install it, you need to:
+  * Enable SPI on the Raspberry Pi using raspi-config
+  * Download and unzip the source code:
+<code bash>
+wget https://github.com/hallard/single_chan_pkt_fwd/archive/master.zip
+unzip master.zip
+</code>
+  * Install the wiring library:
+<code bash>
+apt-get update
+apt-get install wiring
+</code>
+Now you can compile and run the packet forwarder as root.
+<code bash>
+make all
+nohup ./single_chan_pkt_fwd &
