Barcelona's smart city construction is in a leading position in the global rankings. Although it is a top-down planning and construction, the city council does not ignore the role of the community in the construction of a smart city. Barcelona attaches great importance to the transformation and regeneration of the old urban area, and promotes infrastructure construction in the "22@Barcelona" area. Today, "22@Barcelona" has become a smart new urban area with technological innovation. It is a model community in the construction of a smart city in Barcelona. Its wisdom The technical system has been innovatively promoted in nine other cities. Barcelona Smart City is a comprehensive plan that includes all aspects of the city, from information infrastructure, smart social public services, to the green and sustainable development of the city. It is an inclusive and open system.

To build a smart city, first of all, Barcelona's underground comprehensive network has covered the whole city, with a total of 375,000 meters long urban network, FTTH coverage 100% covering the entire city. At the same time, citizens can simply and conveniently obtain free Wi-Fi public access points covering the whole city through APPs. 721 Wi-Fi hotspots allow citizens to obtain network services anytime and anywhere, and enjoy the interconnected network world. "Fibre for the Home" is a pilot project to install a fiber optic network in Poblenou indoors to multiply the bandwidth of the area. And "T-City Friedrichshafen" is an urban digital network, ultra-fast optical fiber and mobile network to improve data transmission and implement applications; among them, there are more than 300 kilometers of optical fiber and the intensive information application technology of the basic city management model.

In addition, Barcelona also attaches great importance to the role of the Internet of Things in smart cities. The city covers a large area of wireless sensors and routers. These devices generate a large amount of data every day. Collect and analyze data on the Internet to provide guidance for more efficient operation of the city. For example, one of the unique functions of the intelligent garbage collection system is that it will actively send out a signal when it is fully loaded, and the staff will arrange the travel frequency and route of the garbage truck according to the signal sent by it, so as to improve the efficiency of garbage disposal. The same is true for intelligent irrigation systems. Ground sensors provide real-time data such as humidity, temperature, wind speed, sunlight, and air pressure. Gardeners can adjust plant irrigation schedules based on basic data and irrigate more scientifically.

Not only that, the smart city of Barcelona has also achieved remarkable results in promoting the development of a low-carbon green environment. In order to reduce carbon dioxide emissions, Barcelona launched a new green city operation plan covering energy alternatives, transport management and green buildings.

The project includes the control of 50 street-level street lights, with a total of 1155 street light masts to LED lighting technology. According to the latest research from the University of Pittsburgh, they can provide the best green alternatives for those cities with life cycle study analysis. Barcelona is expected to reduce its municipal energy bills by a third.
