  This paper presents cniCloud, a cloud-based platform for mobile devices to
share and query the fine-grained cellular information at scale. cniCloud
extends the single-device cellular analytics via crowdsourcing: It collects the
fine-grained cellular network data from massive mobile devices, aggregates them
in a cloud-based database, and provides interfaces for end users to run an
SQL-like query over the cellular data. It offers efficient and responsive
processing by optimizing the database storage and adopting the domain-specific
optimizations. Our preliminary deployments and experiments validate its
feasibility in performing crowdsourced analytics.
