+ \center{Why using Ofono based Java RIL?}
+ \begin{itemize}
+ \item Adds supports for AT modems, could be used to support many devices:
+ \begin{itemize}
+ \item GTA04: Free software bootloader
+ \item Optimus black: Free software bootloader
+ \item PinePhone (EG25 modem?): Will probably have a free software bootloader
+ \item Librem 5 (EG25 modem?): Free software bootloader, nonfree firmware for the DDR4 controller\cite{librem5-ddr4-firmare} on a flash chip $\rightarrow$ No redistribtion issues for Replicant.
+ \end{itemize}
+ \item Already has QMI support. Could be used add support for 4G with the following devices:
+ \begin{itemize}
+ \item Galaxy SIII 4G (I9305)
+ \item Galaxy Note II 4G (N7105)
+ \end{itemize}
+ \end{itemize}
+\end{frame}
+
+\begin{frame}
+ \center{Status}
+ \begin{itemize}
+ \item Already tested on Replicant 6 with a smartphone that uses a Qualcomm System On a Chip (SOC)
+ \item Tested with Voice calls, SMS, MMS, USSD, data, SIM ID, voicemail\cite{README}
+ \end{itemize}
+\end{frame}
+
+\begin{frame}
+ \center{oFono Substainability}
+ \begin{itemize}
+ \item Ofono is Maintained, has several modems and protocols
+ \item Supports GNU/Linux modems (Smartphones with free software bootloaders often run GNU/Linux)
+ \end{itemize}
+\end{frame}
+
+\begin{frame}
+ \center{oFono based Java RIL}
+ \begin{itemize}
+ \item BuildRilWrapper.java\cite{BuildRilWrapper.java} seem to use introspection to build the Framework$\leftarrow$$\rightarrow$ RIL API.
+ \item Last commit from 2017
+ \item Written in Java $\rightarrow$ We would need more people fluent in Java.
