What exactly is a smart city?

Originating in the media field, Smart City refers to the integration of services and urban systems with various innovative concepts or urban systems so as to optimize urban management and services and enhance the efficiency of resource utilization. Smart city is an advanced form of urban informatization that fully applies to the new generation of information technology. Big cities can be alleviated by the deep integration of urbanization. This article will take you to comprehensively understand what is smart city.

2. How do smart cities work

How do smart cities work

The urban planning and architecture should be pleasing to the eye, so that the citizens living in it can cultivate their temperament and have a pleasant mood.

The city of Dubuque partnered with IBM to build the first smart city in the United States in 2009. Various city public resources are connected in a community of 60,000 residents. Dubuque’s first step was to install CNC water meters in all homes and shops. Waste can be prevented by low-flow sensor technology.

Based on the web, South Korea will build a green, digital, seamless mobile connected eco-smart city. Clients can easily conduct medical treatment, tax processing, distance education, and realize intelligent monitoring of home building energy consumption by integrating public communication platforms and ubiquitous network access.

IBM officially put forward the vision of “smart city” in 2010, believing that 6 core systems construct the system, they are business/government, organization, communication, water and energy, and transportation, which are related to the main functions of the city.

3. What technologies are used in smart cities

What technologies are used in smart cities

According to several reports, the smart city industry will see a huge boom in the next five to seven years, with a market valuation expected to exceed $400 billion. In 2020, there are more than 600 smart cities in the world that will play a key role in a reasonable share of global GDP. Smart cities combine the power of technology to provide additional visibility and services to cities. Here are five key technologies that any smart city needs for efficient and sustainable living.

1. Smart energy

Energy is a basic requirement for any smart city. Energy drives all technology and powers human life while working, shopping, eating, playing and even sleeping. Smart cities should provide smart energy for their buildings, which can be achieved by using the latest technology to improve energy efficiency.

All buildings would use energy-efficient lighting systems, including LED lighting that supports digital communication. The main reason for choosing LED lighting systems is that LED lamps can save a lot of energy and pay for themselves in a few years. In addition, LED lights can be easily integrated into the current infrastructure.

To create sustainable energy use, smart cities should rely heavily on renewable energy, the most important of which is solar. Solar power can be the main source of energy for smart cities because it reduces the use of fossil fuels and thus pollution levels. Installing solar systems in commercial and residential buildings is beneficial for the city’s carbon footprint.

All energy is transmitted through the grid, and in the case of smart cities, the grid is smart. Smart grids can help implement useful systems. The smart grid elevates the smart energy ecosystem across the city, enabling the energy sector more competitive.

In conclusion, smart cities should have a robust data system that can collect and analyze data about residents’ energy consumption. The data can be used to create an improved grid management system, create efficient energy distribution mechanisms and regulate electricity production. In addition, residents who monitor their energy use can take concrete steps to reduce costs, which can lower bills and improve the energy efficiency of their homes. But because smart energy systems are digital, they are vulnerable to hacking, making it necessary for agencies to invest heavily in security measures to protect systems from attack.

2. Intelligent Transportation

A city’s transportation system is crucial to maintaining mobility. The current traffic situation in many parts of the world is inefficient and congested. Smart cities transcend all that, however. Smart cities support multi-mode transportation systems, including smart traffic lights, smart parking and electric cars. By implementing the smart parking system, people are more productive because they don’t have to look around for parking Spaces and waste precious time.

Another key area of its impact is traffic congestion. With the implementation of smart parking, people know when and where to park, which helps reduce traffic congestion on the roads.

Smart transportation systems also connect to public transportation, providing citizens with real-time information about when buses and other transportation will arrive. As the transportation system boomed, it collected data on the movement of people, vehicles and traffic flow through a multitude of sensors, which helped reduce vehicle flow and help the city run smoothly and safely.

3. Intelligent data

Data is part of a smart city because it is collected through every sensor, no matter how small, and can be further used. The vast amount of data collected is worthless without analysis. The results can be used to make some adjustments to the city’s system to create a more efficient one once the data is analyzed. Even the smallest amount of data, whether it’s the temperature in your room or how many cars are at traffic lights, can benefit citizens in one way or another. Smart data is one technology it needs to satisfy as smart cities are huge hubs of data sets.

To analyze data requires resources and infrastructure, which is why many organizations are looking for new options to analyze data. The data can then be recommended to the relevant authorities, who can act on it. Therefore, it is important to have a deep understanding of the data and how to analyze it to extract correlations from it.

4. Smart IoT devices

These devices are key components in smart cities. Smart cities should be equipped with actuators and sensors that collect relevant data to improve the city’s different systems. Data from a variety of devices (visibility devices, speed sensors, pollution sensors, etc.) are indeed operational elements of smart cities.

In smart cities, data or information can be retrieved directly from deployed sensors. As more sensors are deployed, the dependence on these sensors increases, and the need for their accuracy and reliability increases, as poor quality severely impacts the systems they are connected to.

But deploying countless sensors in smart cities brings its own set of challenges. Bandwidth availability will be severely challenged unless new technologies are introduced that minimize bandwidth usage even as the number of devices increases when the number of sensors in cities increases. That said, many devices also pose malware or hacking threats, and given the importance of their needs, authorities need to keep them secure.

5. Smart infrastructure

Smart cities should have smart infrastructure that helps cities better analyze data and proactively maintain and plan for the future. For example, systems that can monitor lead levels in a city’s water supply in real-time can prevent serious and large-scale health problems.

Requirements may be large or small though the infrastructure should be in place to handle them. In addition, self-aware infrastructure takes care of itself, reducing downtime and improving operational efficiency.

Key requirements for smart infrastructure come from the need for better data that can help you better understand how your infrastructure behaves in different situations. This data can help transform cities’ buildings, healthcare, productivity, and other systems to increase productivity and reduce carbon footprints while promoting sustainable living systems.

The expansion of digital services in communities promotes civic-connected experiences.

3. Safer Neighborhoods. Smart cities are safer cities. Many cities are already investing in smart technology to help build a safer community.

smart cities are fighting back to reduce their negative impact on the environment with the rise of debris in the ocean and litter on our streets. Air quality sensors, renewable energy and energy-efficient buildings provide cities with new tools to reduce their ecological impact. For instance, deploying air quality sensors around cities could provide data to identify causes of pollution, provide data analysts and track peak times of low air quality.

Investment in smart city transportation is anticipated to grow by up to 25% annually over the next five years. From enhanced traffic management to the ability of mass transit riders to track buses or trains, smart technology can enable cities to better serve their citizens, even as their populations often grow rapidly. Investment in smart city transportation is expected to grow by more than 25% annually over the next five years. Smart parking management allows cities to tap into additional revenue streams. Reduced traffic congestion, the growth of autonomous vehicles and efficient vehicle routing have all reduced the need for vehicle-related space in urban areas, making it possible to expand land for development.

6. Increasing digital assets. Smart city technology creates a more equitable environment for citizens. Individuals must be available for affordable equipment and high-speed Internet services to ensure equity in digital assets. Strategic adoption of public Wi-Fi hotspots throughout the city is able to provide high-speed Internet services.

Efficient Utilities With the limited supply of natural resources to meet human needs, smart technologies provide cities with the tools they need to effectively protect and reduce unwanted waste of water and electricity.

9. Improving the aging infrastructure of roads, Bridges and buildings usually require substantial investment to maintain and repair their useful lives. Smart technology is able to provide predictive analytics to identify areas that need to be fixed before infrastructure fails. These features save cities huge opportunities for tax revenue and life from preventable infrastructure failures.

Advances in autonomous agency capabilities, mobile devices, roaming devices, and sensors allow city employees to shift their energies to more strategic initiatives, reducing the amount of time spent on daily manual operations.

7. What are the challenges of smart cities

What are the challenges of smart cities

Smart city is a novel solution to effectively utilize natural resources, improve residents’ living standards and achieve economic development.

To succeed, however, smart cities’ challenges should first be addressed.

Smart cities have been one of the main topics in the news media for quite some time. Through the use of digital technologies, urban functions can be simplified and optimized while minimizing negative ecological impacts. At the same time, smart cities raise fiscal revenue and improve citizens’ quality of life. Governments, technologists and urban planners are working together to turn this ambitious idea into reality. Governments are also adopting smart governance to implement good governance principles. Moreover, policymakers are implementing procedures and policies to ensure the rapid development of the city. But despite all these efforts, we still haven’t achieved much. That’s because smart cities still have some challenges to solve. The problems that hinder the success of smart cities should first be considered and addressed before any other measures are taken.

1. Insufficient funds

According to a report by SmartCitiesWorld, insufficient funding is the biggest challenge for implementing smart city strategies. In addition, numerous smart devices must be integrated to collect data. In addition, to ensure the success of smart cities, governments must hire enough technical experts and urban planners. In addition, network requirements must be correctly met. In addition, installed hardware must be checked frequently for maintenance. All this requires a lot of money.

2. Lack of experienced professionals

For smart city projects to succeed, technical expertise is needed to identify areas to implement technologies and operate these tools. Governments and relevant stakeholders should count the number of professionals needed and hire them before embarking on project plans.

3. Network connections are inconsistent

To administer a city intelligently, sensors, cameras and actuators are everywhere. The analysis and processing of the collected data should be carried out almost instantaneously in order to effectively manage city operations. For instant processing, a high-speed Internet connection is a must. Currently, 4G mobile networks exist and are not efficient enough for high-speed data transmission. Therefore, this issue must be fully considered.

4. Network security risks

According to IHS, smart city devices are expected to exceed 1 billion units by 2025. While this data helps improve the efficiency of municipal departments, there are also serious security risks that cannot be ignored. Data from security cameras, parking lots, GPS systems and electric car charging stations contain confidential information about citizens. So far, not every connected device is network resilient. Therefore, governments and IT professionals should enforce the security boundaries of smart devices and supporting infrastructure.

Identifying and addressing smart city challenges requires a collaborative approach.

8. Are smart cities safe?

Are smart cities safe

The extent of the damage cybercriminals could cause in a fully connected city.

The benefits of connected cities are many, but as the basis for a range of connected devices, they also show their greatest vulnerability. A utilized sensor can provide an entry point for an attacker, effectively making the entire system insecure.

Without the right cybersecurity measures, smart cities are vulnerable to malicious intrusions and criminal activity. In 2014, for example, researchers were able to hack into nearly 100 wi-fi traffic lights in the U.S. state of Michigan. In this case, researchers infiltrated the network relatively easily by using default usernames and passwords that could be found online. If the act is replicated by a malicious actor, there is a real possibility of a loss of life. Atlanta was hit hard by a ransomware attack on critical municipal systems in 2018.

Every endpoint and node in the network must be secure. Hence, system operators are required to have a thorough understanding of the entire smart city network.

Three-step solution

Security issues and privacy can be addressed in three steps. The first is securing networks and enterprise-level infrastructure systems. This ensures that only commands and authorized personnel can access these devices.

Secondly, proper protection of various connected devices that constitute the network structure of smart cities, such as building control systems and traffic management systems, is crucial to solving the privacy and security problems of smart cities. IoT devices are increasingly under attack by cybercriminals,.

Third, IT is critical that systems architects continue to focus on traditional IT systems that keep employees, municipal data, services, and websites up and running. Forward-thinking smart cities will monitor and protect their surroundings while providing visibility into internal systems that may be under attack.

Safer and smarter cities

Privacy and security incidents within smart cities will become more frequent unless manufacturers of connected infrastructure and smart devices used across cities adopt more appropriate processes, protocols, and security policies.

Having a certificate for device authentication to connect is one step. Actively monitoring and managing the certificate life cycle will create reliable and secure smart cities.

Their vulnerability to bad actors and cyber attacks continues to grow as our utilities, cities, cars and buildings become home to ever more sophisticated computer and data networks. Malicious attackers know how disruptive disrupting these intertwined systems can be to our daily lives.

9. What is the importance of smart city?

What is the importance of smart city?

Smart cities are primarily information and communication technology (ICT) frameworks for developing, deploying, and promoting sustainable development practices in response to growing urbanization challenges.

Citizens can interact with the smart city ecosystem in a variety of ways. Pairing data and equipment with a city’s services and physical infrastructure can improve sustainability and reduce costs.

Citizens’ smartphones will become mobile driving licenses and ID cards with digital certificates, speeding up and simplifying access to the city and local government services.

Why do we need smart cities?

Urbanization is a never-ending phenomenon. There are 54 percent of the world’s population lives in cities. Combined with overall population growth, urbanization will add 2.5 billion people to cities in the next three years.

Social and economic sustainability is essential to keep up with this rapid expansion, which is placing a burden on our urban resources. In September 2015, 193 countries agreed on an agenda for the SDGS at the United Nations.

Citizens and local governments certainly have more flexibility to initiate rapid initiatives, and smart city technologies are critical to successfully achieving these goals.
