Localization
• Need to determine the location:– In real-time– In three-dimensions– Both indoors and outdoors
• GPS
• GSM

GPS
• Global Positioning System
• Satellite-based localization
• Available outdoors worldwide
• Not available indoors

GSM
• Global System for Mobile Communications
• Most widely used cell phone standard
• Available indoors and outdoors
• Designed for voice transmission, not localization…
