\section{Current Progress}
\label{sec:progress}
We modified Android \wifi{} driver to support monitor
mode, which enables the smartphone to collect detailed spectrum measurements.
We have set up a group of OpenWRT APs to experiment spectrum allocation
algorithms. We expect to report preliminary results to show: the value of
detailed client-side measurements, the performance penalty of collecting them
from active clients, and the feasibility of using smartphones to help nearby
devices. We also plan to deploy our system on
\PhoneLab{}\footnote{\url{http://www.phone-lab.org}}---a large
smartphone testbed at UB.
