History of Bluetooth Technology

 




How many in this class have a wireless keyboard? How many have wireless headphones or a JBL speaker? If you have any of these wireless accessories you can thank Bluetooth technology. Bluetooth technology is a wireless system that connects devices together. It is responsible for connecting your computer to your wireless keyboard and your iPhones to your air pods or your wireless speaker. 

Bluetooth technology was invented by Dr. Jaap Haarsen in 1994. It uses radio waves. However, Bluetooth technology would not have been possible if it had not been for a few very important men back in the 1800s. A man named James Clerk Maxwell believed that was an electric magnetic spectrum. He believed that electric magnetic waves could be transmitted through the air rather than through a wire. A man named Heinrich Hertz proved that Maxwell was correct. Hertz was the first person who was able to move electricity without wires. In the early 1900s, Reginald Fessenden created a device that allowed people to transmit their voices. On December 24, 1906, the first voice was sent across the radio waves. Reginald Fessenden wished everyone a Merry Christmas. These men are responsible for the beginning of wireless technology. 

Fast forward to 1994, Haatrsen was working for Ericsson’s Mobile Terminal Division. "He was asked to find a way to enrich the functionality of the mobile phones." The History of Bluetooth He did exactly that! He invented Bluetooth technology by using UHF radio waves. This technology allows devices to be connected and to communicate with each other without wires. This technology relies on short-range radio frequency. Haatsen encountered a problem with WIFI which operated on the same frequency as his new technology. In order to overcome this challenge Haartsen figured out a way "to use frequency hopping techniques to ensure that Bluetooth connections were reliable and tolerant to interference."  The History of Bluetooth 

At this point, you maybe wondering how they came up with the name Bluetooth. It is an interesting story. It started out as just a code name for the project. In 1966, executives from Intel, Ericsson, and Nokia met to discuss this new technology to see if they could make it work with different products and industries. The code name Bluetooth was chosen by an employee who was reading about Vikings at the time. He chose the nickname of a famous Viking king, Harald Gormsson, who happened to have a rotten tooth that looked blue in color. He chose him because he was known for uniting Denmark and Norway. This name was supposed to only be the codename for the project while they were working on it. However, when the time came to actually name it, they were told that the name "Bluetooth" had been used on the licenses and patents so therefore they could not use any other name. That is how the technology came to be known as Bluetooth. 

The History of Bluetooth

Bluetooth technology has transformed how we communicate and share data. This technology has had 5 different versions. It went from Bluetooth1.0 which had basic data transfer capabilities to today's version, Bluetooth 5.0 which has increased speed, and data broadcasting capabilities. The Evolution and Impact of Bluetooth Technology 

The benefits of Bluetooth today include being able to transfer data between devices without using the internet. Large files can transferred quickly. Information is more secure because Bluetooth technology requires a code in order to share information between devices. This makes it difficult for anyone to intercept the information. 

Does Bluetooth have any negative effects? 

Some people are concerned as to whether Bluetooth headphones and other accessories are safe. The concern is that Bluetooth devices emit radiation. The company has stated that Bluetooth devices emit only non-ionizing radiation which is considered safe for human exposure. Therefore, Bluetooth devices should not cause cancer because they do not have the ionizing radiation that X-rays have. 

There are some security concerns. The first concern is if you have a less secure password someone could access your Bluetooth device. Once they have access the person could corrupt your data or steal information off of your Bluetooth device. Another security concern could be if they were able to get access to your device they could put a virus. There are several ways that you can protect your device:

 (1) create a very secure password, (2) disable Bluetooth when you are not using it, (3) use Bluetooth in hidden mode, and (4) do not use public wireless hot spots. Understanding Bluetooth Technology

How has Bluetooth technology changed communications? 

Bluetooth technology has changed not only the way we communicate but also how we live. We now send data between devices without using the internet. We also transfer large files very quickly. Bluetooth technology has changed the way we communicate with others. We can connect our phones to our cars and speak hands-free while driving. Bluetooth technology enables us to wear devices that track and monitor our health and fitness. Bluetooth technology enables us to connect our smart home devices which enables us to control lights, thermostats, and security systems when we are away from our homes.  It has completely transformed our way of life.

 Our world has changed positively and negatively, over the past twenty-five years since scientists at CERN created the World Wide Web. (https://home.cern) The positive changes include how the internet transformed how the world does business. The Internet made doing business, easier, faster, and more efficient. For example, before the Internet, documents such as contracts or invoices, had to be sent through the US Post office, or by courier, or faxed. All of which took time. Thanks to the Internet, these documents can be sent and received immediately through email or text. Another positive is how websites such as Facebook, Instagram, and TikTok enable us to keep in touch with friends and family who may live far away. We can keep them updated with pictures of what we have been up to. However, as wonderful as all of these positives have been, they have come at a cost. The cost has been our privacy. Before the internet existed, we determined who saw our pictures, who we told about our vaca

News Sources-Blog #1

I get my news from several different sources because I like to hear multiple points of view. I want to understand all sides of an issue. I want to hear other perspectives, so I can decide where I stand on any particular issue. Here are five of my favorite news sources.  1. Fox News: To be honest, I started watching Fox News with my parents when I was young. They made me and my siblings watch Fox News, CNN, and BBC every weekend. They instilled in us the belief that it is important to know all the different views so we can make our own decisions. Now that I am old enough to vote I realize that this was really good advice. So now, I watch Fox News because I want to hear the conservative point of view. It is important to get the conservative point of view because it is a Presidential election year. I want to make sure I hear both sides before I vote in November. I would recommend this news source because it will give you the conservative view that you will not get on any of the other main

Values of Free Expression

The Values of Free Expression   After more than a century of religious oppression under European and colonial rule, the framers of the US Constitution sought to create a more enlightened society where fundamental freedoms would be protected and thereby create a stronger country and society. The founding Fathers came up with the Bill of Rights and one of the amendments was the First Amendment which protected the freedom of speech, religion, and the right to assemble from government oppression. Many of these ideas were articulated in the Federalist Papers and were derived from philosophers and economists such as John Locke and John Milton. James Madison, who was one of the authors of the Federalist Papers, "introduced 12 amendments to the First Congress in 1789. Ten of these would go on to become what we now consider the Bill of Rights."  The Constitution In 1859 John Stuart Mill published On Liberty. "Is thought to be the origin of translating market competition into a th
