What are the technological capabilities of smart cities?
Smart and sustainable cities integrate various technologies to optimize services and improve the quality of life of their inhabitants. Some of these include:
Internet of Things (IoT): uses the Internet of Things (IoT) infrastructure of connected devices, collecting real-time data to monitor and optimize environments, such as traffic sensors essential for technological urban mobility;
Artificial Intelligence (AI): AI systems analyze large volumes of data, identifying patterns, predicting problems, and assisting in decision-making to manage urban operations, such as detecting leaks or optimizing traffic;
Gespatial Technology: uses GPS, geographic information systems (GIS), and sensors to map and monitor the urban environment, identifying trends, managing, and assisting with urban mobility challenges and natural disasters;
Advanced Connectivity: a high-speed 5G mobile network is essential for connecting billions of IoT devices, ensuring fast and reliable transmission of data essential for the city’s functioning;
Cloud computing: acts as the central repository for all data collected by the smart city, facilitating the secure storage, access, and sharing of information among authorities and experts;
Data analysis (Big Data): advanced data analysis tools transform collected information into insights, enabling more efficient urban management, continuous improvements, and evidence-based decision-making.
5G connections are essential for data transmission in a smart city.
