in 2010, devicescape applied server-based analysis to curate wi-fi networks discovered by client applications, so that wi-fi networks could be assessed for quality, location, sharing status and other factors. the company referred to this as a "curated virtual network" (cvn) and became a mechanism for offloading traffic from cellular networks. late in 2010, metropcs (now t-mobile) became the first major publicly-announced customer to use the devicescape cvn.
