| OpenSignal | — | OpenSignal - London, UK , permanent At OpenSignal we're using mobile apps to tap into the smart phones we're all carrying around with us to build up global crowdsourced sensor networks. Our first sensor network is for wireless signal [1] where we are building a global database on the coverage and performance of wireless networks both mobile + WiFi on a scale that has never before been possible. Our second sensor network is WeatherSignal [2], which uses the barometers, thermometers and hygrometers on smart phones to crowdsource weather data and we have already published a scientific paper [3] showing the potential of this approach. Our third sensor network is WifiMapper [4] which leverages sensors and the community to build the best free Wifi database in the world. | — | PythonAndroid | apply ↗ | details |
