Municipal governments are leveraging cellular and Low Power Wide Area (LPWAN) wireless technologies to connect and improve infrastructure, efficiency, convenience, and quality of life for residents and visitors alike.
Let's dive in.
What is a smart city?
A smart city is a framework, predominantly composed of Information and Communication Technologies (ICT), to develop, deploy, and promote sustainable development practices to address growing urbanization challenges.
A big part of this ICT framework is essentially an intelligent network of connected objects and machines (also known as a digital city) that transmit data using wireless technology and the cloud.
Cloud-based IoT applications receive, analyze, and manage data in real-time to help municipalities, enterprises, and citizens make better decisions that improve quality of life.
Citizens engage with smart city ecosystems in various ways using smartphones and mobile devices and connected cars and homes. Pairing devices and data with a city’s physical infrastructure and services can cut costs and improve sustainability.
Communities can improve energy distribution, streamline trash collection, decrease traffic congestion, and even improve air quality with help from the IoT.
Connected traffic lights receive data from sensors and cars adjusting light cadence and timing to respond to real-time traffic, reducing road congestion.
Connected cars can communicate with parking meters and electric vehicle (EV)charging docks and direct drivers to the nearest available spot.
Smart garbage cans automatically send data to waste management companies and schedule pick-up as needed versus on a pre-planned schedule.
And citizens’ smartphone becomes their mobile driver’s license and ID card with digital credentials, which speeds and simplifies access to the city and local government services.
Together, these smart city technologies are optimizing infrastructure, mobility, public services, and utilities.
Today, 54% of people worldwide live in cities, a proportion that’s expected to reach 66% by 2050.
With the overall population growth, urbanization will add another 2.5 billion people to cities over the next three decades.
Environmental, social, and economic sustainability is a must to keep pace with this rapid expansion that is taxing our cities’ resources.
One hundred ninety-three countries agreed upon the Sustainable Development Goals (SDGs) agenda in September 2015 at the United Nations.
But we all know how centralized decisions and actions can take time, and the clock is ticking.
The good news?
Citizens and local authorities are certainly more agile to launch swift initiatives, and smart city technology is paramount to success and meeting these goals.
How is IoT technology making cities smarter and better?
Secure wireless connectivity and IoT technology are transforming traditional elements of city life - like streetlights - into next-generation intelligent lighting platforms with expanded capabilities.
The scope includes integrating solar power and connecting to a cloud-based central control system that connects to other ecosystem assets.
These solutions shine far beyond simple lighting needs.
High-power embedded LEDs alert commuters about traffic issues, provide severe weather warnings, and provide heads up when environmental like fires arise.
Streetlights can also detect free parking spaces and EV charging docks and alert drivers where to find an open spot via a mobile app. Charging might even be able from the lamppost itself in some locations!
But how does it all fit together?
What makes smart cities successful
In addition to people, dwellings, commerce, and traditional urban infrastructure, there are four essential elements necessary for thriving smart cities:
Pervasive wireless connectivity
Security you can trust in
Flexible monetization schemes
Let’s break it down.
What’s the best wireless technology for smart cities?
The first building block of any smart city application is reliable, pervasive wireless connectivity.
While there’s no one-size-fits-all, evolving Low Power Wide Area Network (LPWAN) technologies are well suited to most smart city applications for their cost efficiency and ubiquity.
These technologies include LTE Cat M, NB-IoT, LoRa, Bluetooth, and a few others that all contribute to the fabric of connected cities.
The advent of 5G technology is expected to be a watershed event that propels smart city technology into the mainstream and accelerates new deployments.
But only with a few more elements…
Opening the data vault
Historically, governments, enterprises, and individuals have held their data close to the pocket, sharing as little as possible with others.
Privacy concerns and fear of security breaches have far outweighed the perceived value of sharing information.
However, a key enabler of sustainable smart cities is that all participants in the complex ecosystem share information and combine it with contextual data analyzed in real-time. This is how informed decisions are made in real-time.
Multiple sectors must cooperate to achieve better, sustainable outcomes by analyzing real-time contextual information shared among sector-specific information and operational technology (OT) systems.
Stay with us. Here is what we mean.
Examples of smart cities
New York City
You will find below helpful links to some of New York City's major initiatives mentioned in the video above.
The New York City Department of Transportation's Midtown in Motion is a congestion management system that has improved travel times on Midtown's avenues by 10%.
The NYCx Challenges initiative from the NYC Mayor's Office of the Chief Technology officer invites entrepreneurs, technologists, and tech professionals to participate in open competitions and propose bold ideas that solve real urban needs such as pollution, income inequality, and transport.
LinkNYC provides free super-fast free Wi-Fi, phone calls, device charging, and a tablet to access city services, maps, and directions. It's a unique communications network replacing payphones across the Bronx, Brooklyn, Manhattan, Queens, and Staten Island.

Amsterdam Smart City
Amsterdam is a shining example of a well-connected smart city reaping the rewards of opening the data vault. The Smart City initiative began in 2009 and included over 170 projects.
It also shares traffic and transportation data with interested parties such as developers, who then create mapping apps connected to the city’s transport systems.
Now, navigating the city is a snap for all.
The city built autonomous delivery boats called ‘roboats’ to keep things moving in a timely fashion.
It also supported a floating village of houses, solving the city’s overcrowding problem with a sustainable, energy-efficient alternative. Power is generated within communities, and homes receive water straight from the river and filter it within their tanks.
Singapore has been ranked the world’s smartest city. What does a smart city look like on the streets and in the homes of Singapore?
While data sharing is essential, opening the vault also expands the cyber-attack surface area.
So, how do we keep data private from the masses while sharing it among stakeholders?
Can smart cities be secured and trusted?
In digital cities, connected cameras, intelligent road systems, and public safety monitoring systems can provide an added layer of protection and emergency support to aid citizens when needed.
But what about protecting smart cities themselves from vulnerabilities?
How can we defend against hacking, cyber-attacks, and data theft?
In cities where multiple participants share information, how do we trust that participants are who they say they are?
And how do we know the data they report is true and accurate?
The answers lie in physical data vaults and strong authentication and ID management solutions.
Smart cities can only work if we can trust them.
Four core security objectives for smart city solutions
All ecosystem partners - governments, enterprises, software providers, device manufacturers, energy providers, and network service providers - must do their part and integrate solutions that abide by four core security objectives:
Availability: Without actionable, real-time, and reliable data access, the smart city can’t thrive. How information is collected, distilled, and shared is critical, and security solutions must avoid adverse effects on availability.
Integrity: Smart cities depend on reliable and accurate data. Measures must be taken to ensure that data is accurate and free from manipulation.
Confidentiality: Some of the data collected, stored, and analyzed will include sensitive details about consumers themselves. Steps must be taken to prevent unauthorized disclosure of sensitive information.
Accountability: Users of a system must be responsible for their actions. Their interactions with sensitive systems should be logged and associated with a specific user. These logs should be difficult to forge and have reliable integrity protection.
Strong authentication and ID management solutions need to be integrated into the ecosystem to ensure that data is shared only with authorized parties to achieve these security core objectives.
The solutions also protect backend systems from intrusion and hacking.
Thankfully, due to growing digital security concerns, legislation is being introduced to address threats and potential market failure.
For smart cities to thrive, we need to establish sustainable commerce models that facilitate all ecosystem players' success.
The software must be woven into the fabric of IoT solutions to benefit all ecosystem contributors; this includes OEMs, developers, integrators, governments, etc.
Each member’s intellectual property needs to be valued and rewarded.
Subscription software capabilities enable new business models that allow each contributor to extract value from their contribution to the ecosystem.
Subscription-based models offer a way to monetize hardware and software to build smart infrastructures and spread out expenses moving away from a huge one-time CAPEX spend.
Expensive medical equipment like MRI scanners, for example, can be sold on a cost-per-scan basis rather than as a one-time upfront expense for hospitals. This creates a win-win situation for hospitals and suppliers alike.
And one day soon, cities will offer affordable subscriptions to fleets of vehicles shared between owners who may choose from an array of custom options. This move could radically reduce traffic and optimize traffic patterns and ride-sharing.
As urban areas continue to expand and grow, smart city technology is developing alongside enhancing sustainability and better serve humanity.
By leveraging pervasive connectivity, open data, end-to-end security, and software monetization solutions, we can align evolving smart city needs for a much-improved experience for all ecosystem partners.
