Over 7,300 payphones in New York City may be transformed into something much more relevant in this mobile age, as Google proposes to convert them into free Wi-Fi hotspots. If completed, this project would basically blanket the whole city with Google-owned Wi-Fi networks, which in turn would benefit the Internet giant greatly with user location tracking and other valuable marketable data. Similar to Facebook’s lofty plan to bring free Internet access to the whole world, Google is looking to move closer towards the inevitable future of big data and ubiquitous computing.
