Cellphone Activity In Shenzhen

This video visualizes the cellphone activity (call and message) during one day in a Chinese city, Shenzhen. Red areas indicates higher load of cellphone activities and cellphone users. We explored two papers on this dataset. One is to estimate real-time human population distribution from activate cellphone users. The other is to analyze the spatiotemporal operational patterns in cellular networks. We investigate the impact of difference factors on the cellular network operational patterns. Further, we study the robustness of cellphone networks.
