 \subsubsection{Servicability of Collars}
+Because the collars are intended to be battery-based, they will need to be serviced,
+with the minimum goal of replacing or recharging the on-board batteries. This
+must be possible to people with no prior technical experience, as the presence
+of such experience is not guaranteed the expected client base. Other common
+servicing goals, such as cleaning the device, should also be easy to accomplish
+without an understanding of the architecture or implementation of the FGC system.
 
 \subsection{Performance requirements}
+\subsubsection{Battery Efficiency}
+Since the FGC device is battery powered and will require maintenance upon
+reaching low battery levels, it's important that the device is able to
+maintain an operational level of charge for long periods of time. That
+is, the number and duration of servicing actions should be low, in alignment
+with the original goal of reducing human labor. At minimum, the device
+should remain operational for 7 days (1 week).
+
+\subsubsection{Support for Multiple Collars}
+As mentioned above, the goal for hte FGC system is to support large herds of animals,
+which normally require significant portions of time to be dedicated by humans.
+In order to properly support large herds, it must be possible for the system
+to support as many as 100 concurrently active collars without issue. This
+requirement applies to the collars themselves and the Android application:
+\begin{itemize}
+    \item The collars themselves should not experience difficulties when concentrated
+        in large groups (farm animals instinctively tend towards proximity).
+    \item The Android application, given hardware that is not greatly outdated,
+        should be able to display and manage this number of collars without
+        additional delays.
+\end{itemize}

 \subsection{System operations}
 \subsection{System modes and states}
+Besides the "standard" operational mode for the collar, it
+is useful to envision other modes that help in troubleshooting
+and setting up the FGC system. We define the following modes:
+
+\subsubsection{Standard}
+In this mode, the device uses the defined
+"out of bounds" area to determine whether or not to emit a negative
+stimulus. The produced negative stimuli are as defined in the
+sounds and electrical shock section of the functional requirements.
+
+\subsubsection{Electric Shock Test}
+In this mode, the device operates identically to the standard mode
+described above, with the exception of not generating electrical
+shocks. Instead, the device should emit a different sound (or
+a visual signal) to indicate when the shock would have been delivered.
+This allows for safe testing of the device's behavior around area boundaries.
+
 \subsection{Physical characteristics}
+\subsubsection{Weight}
+It's necessary for the device to be physically bearable by livestock for indefinite
+periods of time. If the resulting collar is a constant and noticable weight on the
+farm animal, it would serve as an unnecessary and permanent source of stress. Besides
+the ethical considerations of subjecting an animal to a constant level of stress through
+unnecessary physical labor (i.e. carrying a collar that is too heavy), this goes against
+the purpose of the project, since it will likely reduce the quality of the resulting animal
+management below the level that can be provided by humans.
+
+\subsubsection{Form Factor}
+In order to be able to effectively use the collar, it must fit comfortably on target farm
+animals. In our initial prototype, these animals will be cows, and thus, a requirement
+for the project is that the collar can be put onto, and stay on a farm cow.
+
 \subsection{Environmental conditions}
+\subsubsection{Water Resistance}
+The product will be tested in collaboration with Oregon State University's College of Animal
+Science, and therefore, will be tested in Oregon's climate. Since rain is very common
+during the winter months in Western Oregon, the device must be readily able to withstand
+such conditions, without sustaining any damage.
