  The community cellular networks volunteers and researchers currently rarely
have an access to information about the networks for each site. This makes it
difficult for them to evaluate network performance, identify outrages and
downtimes, or even to show the current site locations. In this paper, we
propose the Community Cellular Networks Coverage Visualizer, a performance
dashboard to help reduce the workload of technicians and gain trust from
illustrating the reliability of the networks. The map displays the overall and
in-depth performance for each current and future CCNs sites with
privacy-focused implementation, while the multi-series line chart emphasizes on
providing the capability of network overtime. Not only it will help users
identify locations that have stronger and reliable signals nearby, but our
applicaiton will also be an essential tool for volunteers and engineers to
determine the optimal locations to install a new site and quickly identify
possible network failures.
