\frametitle{Why?}
\begin{itemize}
\item Pagernetworks are dissapearing.
\item Why do we want to receive messages
\item What is the relevance of receiving only
\item A device that only receives doesn't give away its location.
\item Why encryption (kind of obvious)

\frametitle{LoraWan}
\begin{itemize}
\item synchronised transmitters on the same frequency, like a paging network.
\item Class B can do multicast in a low power mode
\item Normally devices would register on network and then switch to class B
\item If the network would have to support multicast groups that don't need registration, for this to work.
\item There is some open networks being set up (for ex. thethingsnetwork in adam)

\frametitle{Crypto / Addressing}
\begin{itemize}
\item Assymetric crypto.
\item Address is based on public key.
\item Pager can have multiple keypairs (individual key / group keys)
\item Sender of message will encrypt message before giving it to pager network (can be done in a browser).
