 The purpose of the Fenceless Grazing Collar (FGC) system is to reduce the
 need for human supervision in farming through the tracking and automated
 management of individual farm animals, controlled by humans through

+surveillance of all animals.

+\subsubsection{LoRa}
+LoRa (stands for Long Range) is a communication protocol developed by Semtech 
+found on the link layer of the protocol stack. LoRa is a spread spectrum modulation 
+technique derived from chirp spread specetrum (CSS) technology, and excels 
+at long range communication, while keeping battery usage down. LoRa was designed
+exclusively for Internet of Things (IOT) applications, and is able to operate
+with a large number of different LoRa end-nodes.
+\subsubsection{LoRaWAN}
+LoRaWAN is the communication protocol found on the MAC network layer on the network
+stack. LoRaWAN, an open source protocol, interacts with LoRa to transfer data up 
+to the application layer. LoRaWAN leverages the unlicensed radio spectrum in the 
+Industrial, Scientific and Medical (ISM) band. The LoRaWAN protocol is managed 
+by the LoRa Alliance instead of Semtech, and serves to connect all of the end-nodes
+with the gateways and the wider internet.
+\subsubsection{LoRa Gateway}
+A LoRa Gateway is simply the machine that runs LoRaWAN to interact with each end-node,
+and usually directs traffic to another server or the wider internet.
+\subsubsection{LoRa End-node}
+The LoRa end-node refers to each node running the LoRa and LoRaWAN protocol. In this
+project, each collar will be an end-node.
