The Federal Communications Commission (FCC) Speed Test mobile app is a crowdsource project on mobile network performance, collecting millions of samples per month. In order to make the collected information valuable to consumers, a new approach was needed to present this rich resource in timely and intuitive manner. The Visualizing Mobile Broadband project is a web application that presents mobile network information using maps and interactive metrics. Our small team of developers turned to MongoDB for a solution that is flexible and scalable as volume increases and needs evolve. We present our project from conceptual framework to working prototype and highlight organizational obstacles, geospatial and technical issues encountered along the way.
