In today's world, it's hard to imagine life without wireless technologies that connect our devices into a single network. We turn them on every day. Bluetooth on a smartphone to listen to music and connect a laptop to WiFi router for internet access. However, few people realize that these familiar names have deep historical roots and are not simply a random set of letters.
The origins of these terms are shrouded in legends about Scandinavian kings and marketing ploys of the 1990s. Understanding the context of these standards' creation helps us better understand how engineers and marketers shaped the digital future. In this article, we'll take a detailed look at who coined these terms and why they've become so popular.
The history of the naming of technical standards is often surprising. The name Bluetooth comes from the nickname of the Danish king Harald I, who united disparate tribes, just as technology unites devices. This is not just a beautiful metaphor, but a conscious choice by Intel engineers who were looking for a universal code for the new technology.
The Legend of King Harald Blacktooth
In the 10th century, King Harald I ruled Denmark and Norway. His nickname, "Blåtand" (in Danish) or "Bluetooth" (in English), translates as "Blue Tooth." There are several theories about the origin of this strange name. Some historians believe that the king loved to eat blueberries, which stained his teeth blue.
Other sources claim the monarch had a dead tooth, which had turned black and stood out from the rest. Be that as it may, Harald Blacktooth went down in history not for the color of his teeth, but for his political successes. He managed to unite the warring Danish tribes and parts of Norwegian territories into a single kingdom.
It was this ability to unite disparate elements that became a key metaphor for the technology's developers. In 1997, Jim Kardach of Intel was searching for a code name for a new project to unify various communication protocols. He was reading Franz Gunnar Bengtsson's book "The Long Ships," which tells the story of the Vikings and King Harald.
⚠️ Please note: Do not confuse the historical king with mythical figures. Harald I is a real historical figure whose legacy has become a global brand.
Kardakh suggested using the king's name as a temporary code name for the project, expecting the marketing department to come up with something more catchy later. However, the name Bluetooth took root within the company and became so popular among employees that they decided to keep it.
Logo creation and unification of standards
Once the name was approved, the question of visual design arose. The technology's logo had to reflect the essence of the association. Designers at Ericsson, which also played an active role in developing the standard, combined two runes from the Scandinavian Futhark alphabet.
The first rune is - ᚼ (Hagalaz), meaning "hail" or "destruction," but in this context it is the first letter of the name Harald. The second rune is ᛒ (Berkana), meaning "birch" or "birth," is the first letter of the word Björn (the king's middle name). When superimposed, these symbols create the familiar blue icon.
This symbol has become an international standard and is recognized anywhere on the planet. It is important to understand that Bluetooth It was created as a replacement for cables used to connect peripheral devices. Before its introduction, each manufacturer used its own connectors and protocols, which created chaos.
- 🔵 The logo is a stylized combination of the runic letters H and B.
- 🔵 The logo color chosen is blue, which refers to the "blue" tooth of the king and the cold tone of the technology.
- 🔵 The symbol is intended to signify versatility and compatibility across different devices.
Today, we use this technology everywhere, from wireless headphones to smart watches and smart home systems. Bluetooth Low Energy (BLE) revolutionized energy consumption, allowing devices to operate for years on a single battery.
The Myth of Wireless Fidelity and the Reality of IEEE 802.11
If the situation with Bluetooth is relatively clear, then with WiFi There's real confusion. For a long time, it was believed that the acronym WiFi came from the term "Wireless Fidelity," analogous to Hi-Fi in audio technology. However, this is a common misconception.
In fact, the term was coined by the marketing company Interbrand in 1999. The organization Wi-Fi Alliance (then WECA) wanted to create a brand that would be short, catchy, and easy for consumers to remember. The technical name of the standard IEEE 802.11b Direct Sequence was too long and complicated for the mass market.
Phil Belin, one of the alliance's founders, claimed that "Wireless Fidelity" was never the official name. The phrase emerged later, as an attempt to decipher the obscure word "Wi-Fi" and make it sound more technologically advanced. Advertising materials at the time even used the slogan "The Standard for Wireless Fidelity."
⚠️ Please note: The official position of the Wi-Fi Alliance is that WiFi is simply a brand name and is not an acronym or shortening of anything.
Interestingly, the creators didn't even intend for the word to become a household word. They were simply looking for a replacement for a complex technical term. WiFi is associated with high-speed Internet and the ability to work wirelessly anywhere in the home or office.
Marketing Genius: Why WiFi Was Chosen
The choice of the name "Wi-Fi" turned out to be a brilliant marketing ploy. The short, sonorous two-syllable word is easy to pronounce in any language. It's not tied to a specific technology or frequency, which allowed the standard to evolve from 802.11b to modern standards. WiFi 6 And WiFi 7.
Marketers understood that the average user doesn't care about 2.4 GHz or 5 GHz frequencies. They simply need to know that a device "has WiFi." This simplified the technology's adoption. If the standard had been called "IEEE 802.11," its adoption might have taken much longer.
Unlike Bluetooth, which has a specific historical connection, WiFi is purely a branding term. The name has become synonymous with wireless network access. Unlike Bluetooth, the name WiFi has no historical or technical significance beyond a 1990s marketing strategy.
Today, the WiFi logo (a series of arcs radiating from a dot) is also a universal symbol of connectivity. It can be found in cafes, airports, and hotels around the world. It is one of the most successful brands in the history of the IT industry.
The Hidden History of the WiFi Logo
The WiFi logo was developed by Interbrand, the same company that created the name. The design symbolizes radio waves radiating from a signal source. Interestingly, other designs were initially considered, but this one proved to be the most recognizable and easiest to reproduce on device screens.
Comparative table of technology characteristics
To better understand the differences between these two technologies, which are often confused or conflated, it's worth examining their key parameters. Despite their shared purpose—wireless data transmission—they solve different problems.
Bluetooth is designed for low-power personal area networks (PANs), while WiFi is designed for high-throughput local area networks (LANs). Below is a table comparing the key aspects of these standards.
| Parameter | Bluetooth | WiFi |
|---|---|---|
| Origin of the name | King Harald Blezub | Marketing brand (Interbrand) |
| Year of appearance | 1994 (development), 1999 (standard) | 1997 (first 802.11 standard) |
| Range | Up to 10-100 meters (depending on class) | Up to 50-100 meters (indoors) |
| Transfer speed | up to 2-3 Mbit/s (Classic), higher (LE) | up to 9.6 Gbps (WiFi 7) |
| Main purpose | Peripherals, audio, IoT | Internet, streaming, large files |
As the table shows, the technologies don't compete, but rather complement each other. In a modern smartphone, both modules operate simultaneously, providing a comfortable user experience. Bluetooth connects the phone to the watch, and WiFi downloads a movie from the internet.

Evolution of standards and the future of wireless communications
Both technologies have come a long way since their inception. Bluetooth from version 1.0 has reached version 5.4, offering improved sound quality and connection stability. Technology Mesh made it possible to create networks where each device retransmits a signal, increasing coverage.
WiFi is also evolving. The transition to the 6 GHz frequency in WiFi 6E and 7 has reduced airtime congestion and enabled gigabit speeds. However, the naming conventions remain the same: simple numbers for WiFi and versions for Bluetooth.
The future lies in their integration. Devices are learning to automatically switch between technologies depending on the task. For example, a smart lock might use Bluetooth to open the door with a phone, but send break-in reports via WiFi.
⚠️ Please note: Communication standards and protocols are constantly being updated. Speed and range characteristics may vary depending on the specific manufacturer's implementation and environmental conditions.
Engineers continue to work on reducing latency and power consumption. This is critical for the development of virtual reality and the Internet of Things. The names given to these technologies in the late 1990s became the foundation of the digital age.
