What Does It Take To Be A Smart City?
Chicago is a Smarter City Thanks to the Internet of Things & Array of Things
With an abundance of IoT solutions and the introduction of AoT, Chicago distinguishes itself as one of the smartest cities globally.

IoT (Internet of Things) solutions are used in many facets of our lives. These solutions control our business, economy, and well-being. We use these solutions at home, at work, and in our communities.
IoT can be considered an extended intelligence in our lives by providing the connection of smart devices and massive data that transforms into knowledge and real-life actions. We use IoT solutions to manage our homes, workplaces, cars, children, seniors, patients, and even cities.
IoT is one of the most important emerging technology stacks. It is growing so fast that, according to Statista, 30.9 billion IoT units will connect by 2025.
It is estimated to be around 14 billion in 2021. IoT has a substantial impact on our economy and the way we do business and e-commerce.
I posted several articles about IoT on News Break, providing business, technical, and design background. My intention in this post is how IoT is a significant industry in Illinois, especially in Chicago.
To set the context, one of the critical use cases of IoT is the provision of smart cities. A smart city uses various IoT sensors and other electronic devices to collect valuable data, analyze them and optimize resources accordingly.
Some everyday use cases for smart cities can be electricity, water, gas, transportation, traffic management, waste management, crime detection, public safety, and improvement of hospital services.
Another important concept related to IoT is the Array of Things (AoT). This is a critical term for smart cities. AoT is a collaborative effort among scientists, universities, federal and local government, industry partners, and communities to collect real-time data on the urban environment, infrastructure, and activity for research and public use.
One of the enablers of AoT ‘cyberinfrastructructure’ in the US is the Sage project. The Sage project aims to design and build a new kind of national-scale reusable cyberinfrastructure to enable AI at the edge. Sage will be tested both in AoT and NEON (National Ecological Observatory Network) with enhanced climate and environmental measurement capabilities.
The term cyberinfrastructure is worth mentioning in the AoT context as it describes the research environments that support advanced data acquisition, data storage, data management, data integration, data mining, data visualization, and other computing and information processing services distributed over the Internet beyond the scope of a single institution.
The WIFIRE project is an example of ‘cyberinfrastructure’. WIFIRE was funded by NSF 1331615 under CI, IT Research and SEES Hazards programs.
AoT initiatives are empowered by IoT, Edge Computing, and Cloud Computing. A unique platform for AoT is the Waggle Platform. This platform is part of a research project at Argonne National Laboratory to design, develop, and deploy a novel wireless sensor platform with advanced edge computing capabilities to enable a new breed of sensor-driven environmental science and smart city research.
As pointed out in the following diagram from ESI Thought Lab, the use of IoT and artificial intelligence (AI) tops the list for collecting data in hyperconnected cities. Other key data types for determining smart cities are citizen satisfaction, business, channel use, administrative, and social media. In addition, there are several more variables for consideration.
Chicago Smart City Leadership
How do IoT and AoT relate to Chicago?
Chicago is one of the smart cities. In a research report by ESI Thought Lab, In 2019, Chicago was selected as one of the leading cities in the top 100 globally. In fact, Chicago was recognized in the top 25 leading cities. In addition, it was reported in the top 12 smart cities of the US in 2020 by digi.com.
Living in smart cities matters for citizens. According to the Deloitte Managing Director (Piyush Pandey), the smartest cities can become more inclusive through service design, infrastructure planning, and mobility solutions, enhancing liveability and driving more sustainable development and economic growth for all.
Here is an informative video on the Chicago smart city demonstration showing the operation, management, and monitoring by leveraging IoT.
Smart cities not only create and use data effectively but also share it with their citizens. For example, Chicago is a data-rich city. The city has an open data portal that lets citizens find city data, and facts about the neighborhood, and allows them to create maps and graphs about the town. Citizens can freely download the data for their analysis.
Many datasets are updated at least once a day, and many of them are updated several times a day. The open data portal is required under an Executive Order signed by Mayor Rahm Emanuel on December 10, 2012. The open data portal is a valuable service for citizens.
IoT and AoT are all about data and user applications. Chicago has four breakthrough applications for citizens. They are the Open Grid, Chicago Health Atlas, 311 Service Tracker, and Digital Collections.
The Open Grid is the most exciting one of these apps. Using this app, citizens can explore the health of their neighborhood, city services requested through 311, and points of interest in a single, easy-to-use interface. In addition, they can quickly search using keywords or use filters to discover the data they need.
You can learn about the Open Grid from this short YouTube video.
