In 2018, tech publication The Verge declared that “everything is connected, and there’s no going back” — a statement that seems even more true four years later.

When you walk down a city street, hundreds of vehicles equipped with sensors, processors and networking equipment whiz by, and buildings are outfitted with all kinds of antennae and dishes that connect the many smart appliances and personal assistants within them to the internet. If you enter a hospital, a school or a factory, you’ll inevitably come across a plethora of connected devices designed to make life more automated and efficient.

All told, there are more than 13 billion of these connected devices operating around the world today, according to Statista, and in just three years that number will likely double. This massive ecosystem has come to be known as the Internet of Things, or IoT, and it is projected to be worth more than $2,456 billion by 2029.

What Is the Internet of Things (IoT)?

The IoT is a network of devices that are connected thanks to internet connectivity, sensors and other hardware embedded within them. This hardware collects the data, that data is then shared via the cloud and integrated with software, which then analyzes and transmits the data to users via an app or website.

Put simply, it makes previously analog, “dumb” devices “smart” by making them capable of sending information over the web, essentially allowing them to communicate with people and other IoT-enabled things. Everything from smartphones and laptops to thermostats and coffee machines can be a part of the internet of things, so long as they are equipped with the proper hardware and internet connection. 

Indeed, the IoT space has seen quite a bit of innovation over the last several years, transforming everything from manufacturing to healthcare to the very homes and cities we live in.

When you hear the term “smart city,” your mind may wander to images and ideas reminiscent of The Jetsons — that classic 1960s cartoon depicting the now not-so-far-off year of 2062, where robots do our laundry and cars soar across the sky and fold up into briefcases. 

But, in reality, a true smart city is so much more than a world of cool, shiny gadgets and technological advancements. “They’re about designing the advancements of a community’s experience that include elements of culture, music, art and language alongside technology,” Paula Kwan, the former director of Toronto’s Civil Innovation Office said in a 2019 TEDx Talk on smart cities. It’s about innovating so that technology works for us, not the other way around.

Here are some of the companies working to make the vision a reality.

 

HqO is on a mission to help commercial real estate landlords better manage their properties, allowing them to digitally connect with their tenants as well as their building’s amenities. The company’s platform “blends the physical and digital” worlds, allowing landlords to communicate with their tenants, market their spaces, grant security access and more. They can also gather data-driven insights to better address specific needs of tenants.
