Mobile Network Long story short Sharing Between Operators Di Francesco et al. Outline Introduction • Network sharing to reduce Data Available CAPEX and OPEX. Data + + Coverage MNO 1 MNO 1 • When does resource Correlation Time sharing make sense? Space Assessing the • How to assess the MNO 2 = MNO 2 = effectiveness effectiveness of network Results Conclusion & sharing? Future Works MNO 1 +MNO 2 MNO 1 +MNO 2

Mobile Network Data Available Sharing Between Operators Data made available by two operators: Meteor & O2 Di Francesco et al. • Transmitters’ location spread throughout the Republic of Outline Ireland ( > 20.000). Introduction • Coverage (approx.) & sectorization information. Data Available Data Coverage • Detailed call records & data sessions (many million). Correlation • Long observation time (weeks). Time Space • Information on mobile device types usage Assessing the effectiveness (TAC codes > 3.000). Results Conclusion & Future Works Limitations: • Partial mobility information. • Users precise location is unknown. • Datasets have been collected at different time frame.
