The Breathtaking Complexity of the Wireless Spectrum

Explore the high resolution version of today’s graphic by clicking here.

As it turns out, the hottest real estate market may be one we can’t see.

Everything from space exploration signals to HAM radios are vying for room on the radio spectrum, in which frequencies range from 3Hz to 3,000GHz. This spectrum acts as the “transportation system” for all wireless communication, and blocks of it are divvied up for specific uses.

The map above, from the U.S. Department of Commerce, vividly illustrates the complexity of this allocation system.

Plots of “Land” on the Frequency Band

Nearly all of the radio spectrum is already divided into a number of civilian and military uses. Some of the most prominent blocks (turquoise on the map) are set aside for television and radio broadcasting, as well as various types of navigation and satellite communications.

The spectrum also has a number of blocks dedicated to amateur radio and satellite.

It’s worth noting that the allocation map only lays out uses within a specific frequency, and that any number of licenses can exist within a frequency block. For categories like “fixed”, multiple licenses can exist in the same part of band provided they’re far enough apart to avoid signal interference.

Most countries claim ownership over their airwaves, so they each have their own versions of the frequency allocation map. Here are a few others: UK, Canada, and South Africa.

The Spectrum Crunch

It’s predicted that mobile data traffic will skyrocket in coming years as consumers’ appetite for high quality video streaming continues to grow. Rapid increase in mobile data usage isn’t confined to specific markets. It’s a truly global phenomenon.

Rising data consumption, coupled with the explosion in IoT devices and the emergence of the 5G standard, means that space within the radio band is increasingly coming at a premium.

In fact, periodic auctions for space on the spectrum see telecommunication companies shelling out billions of dollars for a piece of the pie. The spectrum auction run by the FCC in 2015 raised nearly $45 billion and 2017’s auction raised nearly $20 billion.

The hills are alive with data

The long awaited move to 5G is a hot topic in the telecommunications world, and for good reason. 5G is the next generation of wireless technology, which will deliver super-fast connections for smartphones and higher capacity for broadband networks. It’s estimated that 5G will be 100x faster than current 4G networks.

Charted: The Jobs Most Impacted by AI

We visualized the results of an analysis by the World Economic Forum, which uncovered the jobs most impacted by AI.

Charted: The Jobs Most Impacted by AI

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

Large language models (LLMs) and other generative AI tools haven’t been around for very long, but they’re expected to have far-reaching impacts on the way people do their jobs. With this in mind, researchers have already begun studying the potential impacts of this transformative technology.

In this graphic, we’ve visualized the results of a World Economic Forum report, which estimated how different job departments will be exposed to AI disruption.

Data and Methodology

To identify the job departments most impacted by AI, researchers assessed over 19,000 occupational tasks (e.g. reading documents) to determine if they relied on language. If a task was deemed language-based, it was then determined how much human involvement was needed to complete that task.

With this analysis, researchers were then able to estimate how AI would impact different occupational groups.

DepartmentLarge impact (%)Small impact (%)No impact (%)

Finance70219
Customer Sales671617
Operations651817
HR57412
Marketing56413
Legal46504
Supply Chain431839

In our graphic, large impact refers to tasks that will be fully automated or significantly altered by AI technologies. Small impact refers to tasks that have a lesser potential for disruption.

Where AI will make the biggest impact

Jobs in information technology (IT) and finance have the highest share of tasks expected to be largely impacted by AI.

Within IT, tasks that are expected to be automated include software quality assurance and customer support. On the finance side, researchers believe that AI could be significantly useful for bookkeeping, accounting, and auditing.
