Why Bluetooth Is Named After This Famous King

Why bluetooth is named after this famous king

Bluetooth is one of the most useful wireless transmission technology today, which is great for file transfer and connecting. Portable Speaker, Headphones, wireless mice and keyboards. But what is Bluetooth? Where did its unique name come from?

In short, it is a short-range wireless communication technology that uses radio waves to transmit information, much like Wi-Fi. But where this wireless standard operates semi-permanent networks and can do so over a vast distance, Bluetooth is generally more limited and personal than that.

The term Bluetooth comes from an episode of the Danish king of the 10th century Harald “Bluetooth” Gormsson, Who, through non-violent discussion, gathered the tribes of Denmark into a single state, unified Denmark and Norway, and was noted as a great communicator. No one knows the true origin of King Harald’s rule, but historians speculate that he had a decayed or diseased tooth that darkened it in color.

When the founders of Bluetooth decided on a name for technology designed to unify wireless devices, it was named after the person responsible for integrating Scandinavia. They also scored the Bluetooth logo for their initial H (H) and ᛒ (B) combined Yunger Futhark runs.

Bluetooth story origin

The year is 1996. Nirvana is the king of the airwaves, Pokémon is everywhere, Bill Clinton has won re-election, and the Yankees have won the World Series (to the great Charigin of Red Sox fans). Along with these cultural events, Lund, Sweden was being met with a cocks from Sweden, in which a new technology was developed, to develop new short-range wireless technology. The group includes Intel, Nokia, Ericsson and many more An account written by Jim Kardach, A retired chief electrical architect at Intel.

According to Kardach’s account, he and Sven Matheson from Ericsson made a presentation on an earlier business trip from Toronto and set out on a winter pub crawl that evening.

“Being a big history fan, I trade history stories with Sven. Now, Sven knew a lot about radio, but not much about history, but he did read this book (which at a later date he gave me a copy of) Companions By Francis G. Bengtsson and through this story will be related to history, ”wrote Kardach. “In this book, a couple of Danish warriors traveled the world in search of adventure, and during this time King Harald was Bluetooth.”

Kardach dug up the bizarre name and later discovered that Bluetooth united Denmark and Christianized the Danes. It was an ideal codename for a technology that would integrate devices through short-distance radio transmissions. But codenames have codenames, and product names are usually boring. The group eventually settled on the PAN or individual area network.

“About a week later, an emergency meeting was called,” Kardach continues. “Other member companies did a trademark search on the word PAN and ensured that it would be a poor candidate for a trademark: an internet search produced tens of thousands of hits. It turned out that no trademark search was done on the backup name (Radio Wire) and only the name we could go on to launch with any other information. “

How does Bluetooth work?

Bluetooth works by sending information over ultra-high-frequency radio waves and works within industrial, scientific and medical (ISM) radio bands. It operates between 2.4 and 2.485GHz frequencies, as many Wi-Fi devices do, which can cause problems with disruption when both technologies run concurrently or multiple devices are run in the same region.

Wi-Fi operates asymmetrically (with one access point and multiple devices), while Bluetooth works symmetrically, with one Bluetooth device connected to another. Users can connect up to eight devices over a Personal Area Network (PAN) – in the case of smartphones, this usually means connecting two handsets for file transfer, Bluetooth speakers to smartphones, etc.

Unlike Wi-Fi, Bluetooth connections do not use your cellular data package because they are not transmitting data over the airwaves in the same way. Bluetooth is exclusively device-to-device transmission with no intermediary.

Bluetooth usually works over short distances to conserve power. Although Bluetooth can operate within a range of 200 meters, which is very uncommon, most devices typically run within 10 meters of each other.

To make your radio transmission more difficult, Bluetooth uses An adaptive frequency-hopping spread spectrum, Which automatically changes the radio frequency 1,600 times per second. The transmitted data is split into packets and then sent across randomly selected channels, avoiding any incredibly busy ones. Said that the anti-snooping feature is just one area that has improved through successive generations of Bluetooth technology.

What does Bluetooth use?

Although initially designed with a specific use in mind, today Bluetooth is used to send data over short distances across many devices. Your wireless speaker and Wireless headphones Communicate with your smartphone or home hub using Bluetooth technology. If your car is only a few years old, it is likely that its sound system has Bluetooth connectivity – although It is also easy to add to older cars.

Most laptops are equipped with Bluetooth, making it easy to connect wireless peripherals such as keyboards, mice, and in some cases, printers and scanners. Desktop PCs also sometimes have this, but you’ll often see them connecting to Bluetooth via a USB dongle.

Most game consoles use Bluetooth in some way for wireless connections, but only PlayStation 4 natively supports third-party Bluetooth devices. Is here How to connect your PS4.

Recently, devices featuring the Internet of Things (IoT) have begun to support Bluetooth technology. This can be a low-power way to connect them to a central hub or mobile device. However, they are also likely to be connected via your Wi-Fi network, especially if it operates through an outlet.

Bluetooth version

Bluetooth was first conceived in its abstract form in the late 1980s but was not realized in actual technology until 1994.

Bluetooth 1.0 was broadcast as 1.0a and 1.0b in 1999 to fix some minor issues, and again in 2000 as version 1.0b + CE. In the same year, the first Bluetooth-equipped mobile phones, PC cards, and laptops were released. More products, including the long-desired Bluetooth headset, will follow in the coming years, which helped kick-start the development of the standard in the first place.

In 2004 the Bluetooth 2.0 standard was introduced and enhanced data rates were introduced, which improved the transfer speed to 3Mbit per second. It also reduced power needs, which would be a frequent goal of Bluetooth developers in the coming years.

Speed ​​was again improved by Bluetooth 3.0 in 2009, raising theoretical data rates to 24Mbit per second. However, both it and its successor, Bluetooth 4.0, took advantage of the 802.11 standard (typically used in Wi-Fi) for the fastest transfer.

Probably the most significant upgrade with fourth-generation Bluetooth came with version 4.2: Bluetooth Low Energy. Today, most smartphones worldwide support the standard, and it allows for the same coverage and the same bandwidth, depending on individual usage, significantly cutting power requirements for data transmission. Said innovation not only reduced the demand for Bluetooth on user-controlled devices, but also made it easier for portable speakers, fitness trackers and IoT devices to work longer between charges.

The 2016 release of Bluetooth 5 offered users greater speed and range, as well as enhanced security. Devices can optimize connections for greater speed or by prioritizing up to four times if necessary.

In January 2019, Bluetooth 5.1 introduced Bluetooth tags, a feature that helps people find a car key, purse or remove without any hassle. It can also alert smartphones about information and relevant content at museums, galleries and other public places.

In January 2020, Bluetooth launched version 5.2. It includes LE audio that plays on Bluetooth LBE, LE Isochronous Channels, Power Controls and an enhanced feature protocol.

Bluetooth is all backward compatible, meaning you don’t need to update accessories to match the new technology, making Bluetooth a great feature for all your devices. No matter what, you will not have to worry about the aging of your product due to a system update.
