 \section{Conclusions}
 \label{sec:conclusion}
 
-In this paper, we show that reciprocal \wifi{} sharing opportunities do exist in
-real life scenarios through extensive analysis of the \PhoneLab{} \wifi{}
-dataset. We present the design of \wisefi{}, a system that detects
-reciprocal sharing opportunities, enable \wifi{} sharing and monitor the \wifi{}
-usage and performance to ensure the sharing remains reciprocal.
+To conclude, we explore the reciprocal sharing opportunities through extensive
+analysis of the \PhoneLab{} \wifi{} dataset, and show that such opportunity does
+exist despite the spatial sparsity. Inspired by the analysis results, we present
+the design of \wisefi{}, a system that detects reciprocal sharing opportunities,
+enable \wifi{} sharing and monitor the \wifi{} usage and performance to ensure
+the sharing remains reciprocal.
 
 We are currently implementing a \wisefi{} system prototype, which includes a
 \wisefi{} Android application, dynamic AP configuration API support on OpenWRT
