“Which Technologies To Use For A Better Smart City?”

Key technologies used in a Smart City

Technological literacy is certainly a key to show a city into a smart city. That is not only well connected, sustainable and resilient but also where information isn’t just available but also findable. It is not a replacement thing as a smart city is all about providing smart services to its citizens which may save their time and ease their lives. In the same vein, it’s about connecting them to the governance where they will give their feedback to the government as of how they desire their city to be. However, this aim can’t be transformed into reality without technology.

Using technology, the officials are then ready to gather city intelligence and when we integrate this intelligence with the operations, it make the cities smarter and safer.

Let’s have a glance at six technologies without which smartness of a city can never enhance.


1. Information and Communication Technology

ICT certainly plays a big role in helping cities reduce their carbon footprint. Thus, making them a far better place to measure by enabling far better use of energy in buildings and districts, transport and smart services for citizens.

So, ICT builds a bridge between the citizens and therefore the government where the previous can interact with the govt and reciprocally, the govt can build a city as per the selection of its citizens. ICT also helps the govt to research the demand pattern of the state and thus create a pool of resources to deal with an equivalent online. Additionally, the electronic medium of communication during a community helps in creating a collective intelligence. This will be deployed for resource optimization with the assistance of analytics and deep learning.


2. Internet of Things

Internet of things is analogous to the veins of a city spread all across and connecting each dot. Every device that’s a part of a sensible city must be connected to every other in order that they will talk and take decisions which reciprocally allows managing resources of a megacity population. this is often where the IoT comes in, providing the right template of communicating devices that provide smart solutions to everyday problems. Therefore, all smart solutions in smart cities are dependent on the Internet of things. Here, they connect and are smart enough to make a decision their action.

Case study:

Tokyo-Smart city

Tokyo, for instance, is that the city with the world’s largest population density and keeps growing. Also, out of its 38 million large population, it’s been forecasted that 60% of the world’s population will sleep in major cities by 2030.

Consequently, there arise problems like freshwater scarcity, the pile of garbage, collapse of traffic and pollution. However, the last word key to all or any these issues is sensible City- the networked and intelligent city. It includes a huge list comprising smart infrastructures, smart parking, traffic management, also the town Air Management Tool (CyAM), etc.


3. Sensors

Sensor technologies are certainly latent but ubiquitous components of the urban landscape. These are an important component of any intelligent system. It’s consequently fitted with an array of sensors, from which it collects the specified data. It then uses acceptable variables to characterize its environment and adjusts its operations accordingly. The supply of a mess of various sensors and continuously evolving technology further enables applications that were infeasible within the overdue to high costs and limited availability. Similarly, sensors are like converters which convert parameters of a physical nature to a signal. this will then be interpreted by humans or are often fed into an autonomous system. Moreover, these signals for conventional sensors, amongst others, include light, pressure, temperature, humidity, moisture and a spread of other parameters.


4. Geospatial technology

Whatever is made in a smart city has got to be right and so to create it, we need a right plan which is sustainable. This further requires accurate, concise and detailed data. So, here comes the role of Geospatial technologies which give the underlying foundation and ultimately the material upon which the solution often builds. It provides location which allows pinpointing exactly on the necessity so that a better solution can be applied thereto. Geospatial technology further provides a necessary framework for collecting data and remodeling observation to facilitate a software-based solution around smart infrastructure.


5. Artificial intelligence

AI and Smart City

The smart city is certainly a digital revolution generating an enormous amount of knowledge. Those data are of no use until and unless they’re process, which generates information reciprocally. This massive amount of data generation subsequently brings the role of AI which will add up out of these data.

To understand the interesting aspect of AI technologies within the context of smart cities, allow us to take an example. During a system where energy spikes tend to happen, AI can then learn where they typically occur and under which circumstances. This information then helps in better management of the power grid. Likewise, AI also plays a task in intelligent traffic management and healthcare facilities.


6. Blockchain

Blockchain application is a new smart city concept. This technology certainly secures data flow. Its integration into smart cities could better connect all city services meanwhile boosting security and transparency. In some ways, blockchain can influence cities through smart contracts, which help with billing, processing transactions and handling facilities management. Also, smart contracts are self-executing contracts with the terms of the agreement between buyer and seller directly written into lines of code. They allow trusted transactions and agreements to be administered among disparate parties without the necessity for a mediating third party. Thus, making the method safer, cheaper and faster. Blockchain also can be utilized in smart grids to facilitate energy sharing, an idea which is trending lately.

Smart energy management, smart healthcare, smart citizen services, smart communication, smart governance – of these thus, define a sensible city.

To explore the role of each of those components and also to know better how the technologies listed above are creating the digital infrastructure of smart cities, we recommend you to attend the Geospatial World Forum 2021. (GWF).
