Proximity and beacon data platform Unacast has released its Q4 Proximity.Directory report.
The document focuses on smart cities and how beacons and other location sensors are being deployed for a range of uses that include tourism, marketing, energy efficiency and urban planning.
The previous quarterly report examined uses of beacons in airports.
Demographic predictions argue that 66 percent of the global population will reside in cities by 2050.
Currently, 82 percent of the US population lives in urban areas.
Location technologies in smart cities thus have the potential to touch billions of people by the middle of the century if trends continue.
