The authors present LiveLab, a methodology to measure real-world smartphone usage and wireless networks with a reprogrammable in-device logger designed for long-term user studies. They discuss the challenges of privacy protection and power impact in LiveLab and offer the solutions. This paper presents an iPhone 3GS based deployment of LiveLab with 25 users intended for one year. Early results from the data collection so far highlight the unique strengths and potential of LiveLab. The authors have two objectives in this position paper. First, they demonstrate the feasibility and capability of LiveLab. By sharing their experience, they seek to advocate LiveLab as a network and user measurement methodology. Second, they present their preliminary findings, and seek feedback from the community regarding what data to collect.
