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.

mobile data consumption growth

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.

Cost of Mining Bitcoin in 198 Different Countries

View a higher resolution version of this map.

It takes an estimated 1,449 kilowatt hours (kWh) of energy to mine a single bitcoin. That’s the same amount of energy an average U.S. household consumes in approximately 13 years.

Given the high amount of energy needed to mine bitcoin, it can be a costly venture to get into. But exact prices fluctuate, depending on the location and the cost of electricity in the area.

Where are the cheapest and most expensive places to mine this popular cryptocurrency? This graphic by 911 Metallurgist provides a snapshot of the estimated cost of mining bitcoin around the world, using pricing and relative costs from March 23, 2022.

How Does Bitcoin Mining Work?

Before diving in, it’s worth briefly explaining the basics of bitcoin mining, and why it requires so much energy.

When someone mines for bitcoin, what they’re really doing is adding and verifying a new transaction record to the blockchain—the decentralized bank ledger where bitcoin is traded and distributed.

To create this new record, crypto miners need to crack a complex equation that’s been generated by the blockchain system.

Potentially tens of thousands of miners are racing to crack the same code at any given time. Only the first person to solve the equation gets rewarded (unless you’re part of a mining pool, which is essentially a group of miners who agree to combine efforts to increase their chances of solving the equation).

The faster your computing power is, the better your chances are of winning, so solving the equation first requires powerful equipment that takes up a lot of energy.

The Costs and Profits of Mining Bitcoin in 198 Countries

Across the 198 countries included in the dataset, the average cost to mine bitcoin sat at $35,404.03, more than bitcoin’s value of $20,863.69 on July 15, 2022. Though it’s important to note that fluctuating energy prices, and more or less miners on the bitcoin network, constantly change the necessary energy and final cost.

Here’s a breakdown of what the cost to mine one bitcoin in each country was in March 23, 2022, along with the potential profit after accounting for mining costs:

Venezuela ranks as the number one most expensive country to mine bitcoin. It costs a whooping $246,530.74 to mine a single bitcoin in the South American country, meaning the process is far from profitable. Energy costs are so expensive in the country that miners would be out $225,667.05 for just one bitcoin.

On the opposite end of the spectrum, the cheapest place to mine bitcoin is in Kuwait. It costs $1,393.95 to mine a single bitcoin in Kuwait, meaning miners could gain $19,469.74 in profits.

The Middle Eastern country has some of the cheapest electricity in the world, with one kWh costing an average of just 3 cents. For context, the average cost of one kWh in North America is 21 cents.

The Race is On

Despite the steep costs of bitcoin mining, many people believe it’s worth the upfront investment.

One thing that makes bitcoin particularly appealing is its finite supply—there are only 21 million coins available for mining, and as of this article’s publication, more than 19 million bitcoin have already been mined.

While the price of bitcoin (BTC) is notorious for its volatility, its value has still grown significantly over the last decade. And if cryptocurrencies become mainstream as many people believe they will, this could boost the price of bitcoin even further.

Animation: The Rise and Fall of Popular Web Browsers Since 1994

In its early stages, the internet was a highly technical interface that most people had difficulty navigating. But that all changed when the Mosaic web browser entered the scene in 1993.

Mosaic was one of the first “user-friendly” internet portals—although by today’s standards, the browser was actually quite difficult to access. Comparatively, modern browsers in high use today have changed exponentially.

This animated graphic by James Eagle chronicles the evolution of the web browser market, showing the rise and fall of various internet portals from January 1994 to March 2022.

The 1990s: From Mosaic to Netscape

In the early 90s, Mosaic was by far the most dominant web browser. At the time, about 97% of all internet searches were done through this popular web portal.

Web browser% Share (January 1994)
Mosaic97.0%
Other3.0%

Mosaic was the first web browser to display images directly on a page in line with text. Earlier browsers loaded pictures as separate files, which meant users have to click, download, and open a new file in order to view them.

The pioneering portal was created by a team of university undergrads at the University of Illinois, led by 21-year-old Marc Andreessen. When Andreessen graduated, he went on to be the co-founder of Mosaic Communications Corporation, which evolved into Netscape Communications Corporation, the company that created Netscape Navigator.

Netscape was essentially a new and improved version of Mosaic, but since the University of Illinois owned the rights to Mosaic, Andreessen’s new company couldn’t actually use any of the original code.

Netscape became a nearly instant success, and as a result, Mosaic’s market share began to fall. By the late 90s, Netscape had captured 89% of the web browser market.

Web browser% Share (April 1996)
Netscape88.9%
Mosaic7.2%
Internet Explorer3.9%

Netscape dominated the market for a few more years. However, in the new millennium, a new tech giant started to take over—Internet Explorer.

The 2000s: Internet Explorer Enters the Chat, Followed by Firefox

In 1995, Microsoft launched Internet Explorer as part of an add-on package for its operating system, Microsoft Windows 95.

Given the popularity of the Windows franchise at the time, Internet Explorer was quickly adopted. By the early 2000s, it had captured over 90% of the market, reflecting Microsoft’s hold on the personal computing market.

Web browser% Share (January 2000)
Internet Explorer76.6%
Netscape18.4%
Opera0.7%
Other4.3%

Netscape was mostly phased out of the market by then, which meant Internet Explorer didn’t have much competition until Mozilla entered the arena.

Founded by members of Netscape, Mozilla began in 1998 as a project for fostering innovation in the web browser market. They shared Netscape’s source code with the public, and over time built a community of programmers around the world that helped make the product even better.

By 2004, Mozilla launched Firefox, and by 2006, the free, open-source browser had captured nearly 30% of the market. Firefox and Internet Explorer battled it out for a few more years, but by the mid-2010s, both browsers started to get leapfrogged by Google Chrome.

Present Day: Google Chrome is King of the Web Browsers

When Google’s co-founders Larry Page and Sergey Brin pitched the idea of starting a Google web browser to CEO Larry Schmidt in 2003, he was worried that they couldn’t keep up with the fierce competition. Eventually, the co-founders convinced Schmidt, and in 2008, Google Chrome was released to the public.
