  5. IEEE International Conference on Sensing, Communication and Networking (SECON16) Device-level Data Although devices are detected fairly, Obviously, the data have a relation- ship with the bus running status, then, which part of the packets should be aggregated into a new piece of device-level information? their data tell different stories. Estimate Urban Traffic with WiFi University of Science & Technology of China (USTC) 5
