OpenSignal: Global Map of Cellular Coverage

Via Google I learned about OpenSignal, which provides a cellular signal coverage map.

From their about page: "With your help, we're creating a comprehensive database of cell phone towers, cell phone signal strength readings, and Wi-Fi access points around the world. Our goal is to become the global authority on wireless networks. On this website we provide visualizations and analysis based on the data we've collected, including cellular coverage maps that show exactly how strong signal is in any particular area, as well as all the nearby towers for your carrier. […] In return for users submitting their signal strength data, we pledge to generate a coverage map and make it available for anyone around the world to view, for free, at any time!"

However, its data is not open like the OpenCellID project we mentioned in.
