\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.
