+into traffic or another dangerous location. We specify
+the maximum uncertainty in the location of an animal to be
+3 feet.
+
+In addition to being precise with the GPS coordinates, the system
+must be tolerant of the aforementioned uncertainty. The analysis
+of the reported location should prevent the possibility of a collar 
+not producing a negative stimulus due to a fluctuation of measurement.
 
 \subsubsection{Sound and Electrical Shock}
+Simply being aware of the animal's location is insufficient
+to properly control its behavior without human intervention.
+As such, the collars must be able to create stimuli
+that farm animals find unpleasant, effectively training
+them to avoid performing actions that are undesirable. The sound
+and shock must not only be sufficient to infuence the animals,
+but also safe: they should not cause harm or excessive discomfort
+to the animal.

+\subsubsection{Control Application}
+The project must contain a functional mobile application for

+in the field. This application should, at minimum, be usable

+\subsubsection{Effective Area}
+Because many farms have significant numbers of livestock, and consequently
+a large grazing area, it's necessary that the FGC system is functional
+at large distances. We require that the sysem is functional at distances
+as large as 5 kilometers, which is half of the maximum range of the
+LoRa technology. A consequence of this requirement is also that the system
+is entirely wireless, since it is not feasible to provide cables or wires
+that span the maximum area of 5 kilometers.

+\subsubsection{Accessibility of Application}
+Because the FGC system is intended to be used by farmers as a replacement
+for manual labor, it must be accessible to farmers with knowledge
+of the domain, but not necessarily of the inner workings of the FGC implementation.
+Thus, the final Android application must be usable, without significant prior training,
+by non-technical people from the agricultural industry. On the other hand,
+if necessary, the Android application \emph{should} assume domain specific knowledge
+in the area of agriculture, since its intended audience is from this field.
