 \section{Introduction}

-As personal wireless devices proliferate over the last decade, more and more
-\wifi{} Access Points (APs) are deployed to meet the increasing demand for
-pervasive network access. By the end of 2014, 451 million households worldwide
-(65\% of total the 690 million) use wireless routers to extend their network access
-beyond the fix-line broadband, and the penetration is expected to
-grow to 80\% by 2018~\cite{survey}.
+Two trends are combining to create increasingly crowded and uncoordinated
+home \wifi{} environments. First, increasing broadband penetration is leading
+larger numbers of users to set up private home access points (APs). Strategy
+Analytics estimated that by the end of 2014, 451~M households worldwide
+(25\%) would have home \wifi{}, and this number will continue to
+grow~\cite{wifi-survey}. Second, urbanization is causing an increasing
+percentage of the world's population to dwell in close quarters in dense city
+environments. 54\% of the world's population already resides in cities, and
+that number is expected to grow to 66\% by 2050~\cite{urbanization-survey}.
+Together these two trends combine to create a future in which more people
+will operate private home networks that compete for spectrum with other
+nearby private home networks.
  
 However, due to factors such as blockage or fading in wireless signal
 propagation, home \wifi{} AP usually does not provide equally satisfying \wifi{}
