It is really difficult to find a definitive explanation of what a smart city means because of the breadth of the technologies that in general can be incorporated into a city so that it can be considered a smart city.

Among some of the definitions by professionals in the field, we have that of Mark Deakin, which defines the smart city as a city that uses ICTs in order to meet the demands of its citizens and the community in general.

WHAT IS A SMART CITY?

It is important to know that although what is considered a smart city in one place, it may not be that in another place, however with the rise of the internet of things, we can form a generalized definition that meets the necessary characteristics of what should be considered A smart city

A smart city is a designation or name given to a city that incorporates information and communication technologies (ICT) with the goal of improving the quality and performance of urban services, be it transportation, energy, and public services, in order to reduce the consumption of resources and various general costs.

There are several factors that will be considered and attributed to a city to be considered an intelligent city, such as:

–  Application of a wide variety of digital and electronic technologies to the city and also to the communities that comprise it.

–  If there is application of ICT to improve life and work environments in the region.

–  It is important to also take into account the incorporation of such ICTs in government systems and in the event that this occurs, it is definitely a smart city.

– An infrastructure that is based on technology

– Environmental initiatives with great impact

– A high-functioning public transport system

-A safe sense of urban planning

HOW A SMART CITY WORKS?

Normally, smart cities can use the network of connected IoT devices as well as other technologies in order to improve the quality of life and act in terms of economic growth. For an itinerant city to be successful, the following aspects must be taken into account:

  • Gathering: the city must have intelligent sensors to collect data in real time.
  • Data analysis: all previously collected data will be evaluated in order to obtain meaningful information.
  • Communication: all information and knowledge that has been obtained in the analysis phase must be communicated with decision makers through solid communication networks.
  • Action: once all the above has been carried out, the cities use the knowledge extracted in order to create solutions, optimize operations and of course carry out asset management to improve the quality of life of residents.

SMART CITY TECHNOLOGY

The smart city technology´s secret, lies behind the importance of its impact on the initiatives they propose, usually based on improving pollution levels or traffic conditions, but the main thing is the IoT.

The IoT is a network of physical devices that are connected to each other, such as vehicles or appliances, this allows these “things” to connect and exchange data, collecting information that will work for the user. At the same time, this is creating opportunities that were not previously present that seek to converge the physical and the digital, using data analysis, in order to provide a better, much more efficient service, generating economic benefits and quality of life.

Understanding the true value of IoT will allow cities committed to technology to collect and sort information from isolated city applications.

As well as allowing a clear path in terms of future smart cities that can control everything, from lighting, parking, traffic, citizen participation, security, waste collection, and many other diverse factors that make up a city.

It is crucial and important that we know and understand the technologies involved in the construction of this type of cities, since the IoT is very broad and therefore the technology of smart cities is too.

  • 5G technologies: If there is no powerful network, then the smart city is nothing more than a utopia.

5G technology has the incredible job of boosting the next level of connectivity for industries and these in turn to society. Currently, service providers are actively working on various 5G technologies and want to boost all smart city networks.

  • Sensors: These are usually integrated into each physical device that is fundamental to the internet of things. It goes from the clock marks steps to that connected car that opens the garage door.

 

The truth is that everything in contact today includes sensors that collect and then transmit data to the cloud, and then be used.

  • Geospatial Technology: In the process of building the urban planning of smart cities, precision is required and also a correct analysis and use of detailed data. Then geospatial technologies meet the objective of providing the underlying basis on which each solution will be built in the future.

With this technology there are benefits such as the proportion of the location and the necessary framework to be able to collect and analyze data, and once done, you can transform such data in a way that facilitates solutions based not only on software but also around infrastructure of the smart city.

  • Virtual Reality: In the process of development of smart cities and the technology of smart cities, things like Virtual Reality (VR) and Augmented Reality (AR) take on leading roles in this Fourth Industrial Revolution.

This type of thing requires a massive amount of data and of course they need it quickly since otherwise they will not be able to provide the experience of virtual reality or virtual reality on the move. Hence the importance of preparing 5G networks around the world as this is the first step so that the success of these technologies can be guaranteed.

Smart city concepts: from smart apartments to smart traffic

There are certain aspects of smart cities that make it what they are now.

  • Smart Infrastructure: With a massive analysis of large volumes of data, we will find proactive maintenance and better planning for the future. Then we find an important feature, which is the infrastructure. In a smart city we will see how the IoT goes into action, with smart apartments, buildings, businesses, etc.

Because the infrastructure is considered a fertile land, then there are many plans for it since it will possibly provide the necessary urban growth and evolution for the territory. This is about having an infrastructure capable of adapting to environmental and city changes.

  • Smart energy: In a smart city, all sites are efficient and use less energy, and the energy used is analyzed to gather information that is relevant. From smart networks and street lamps, they are intelligent aspects that mark the entrance of an intelligent city, since LED lights are cost effective. There are also smart meters that are installed in homes.
  • Smart transport: In a smart city, vehicle traffic is reduced, thus facilitating the transport of goods and of course also of people. At the same time traffic accidents and pollution levels are reduced

SMART CITIES AROUND THE WORLD

  • Tokyo: Tokyo is a city that recently joined brands such as Panasonic in order to build an eco-burb, that is, a suburb that will have houses with solar panels, in addition to storage batteries and of course low consumption appliances.
  • Barcelona: The city located in Spain is undoubtedly one of the pioneers in terms of smart cities.

It was one of the first cities in the world to launch a solar thermal ordinance
