10 curious facts about Bluetooth technology

Nearly all devices currently available on the market support Bluetooth technology. But what is Bluetooth? Simply put, Bluetooth is a way for two nearby gadgets to transfer data to each other.

From Use Use of has picked up curious information about Bluetooth technology. From that we learn about the difference between Bluetooth and other common wireless technologies like Wi-Fi or NFC, which are the disadvantages of technology, where the name comes from and so on.

What is Bluetooth?

Bluetooth is a wireless technology standard that aims to offer the ability to connect gadgets between them without a cable. The Bluetooth module is a small part of the chip on your device, enabling wireless communication with Bluetooth devices on other devices. Generally, Bluetooth is used to transmit small amounts of data to avoid using too much battery and maintaining a stable connection at a short distance.

Who invented Bluetooth technology?

Bluetooth technology has been developed by a team of engineers working for Ericsson. Ericsson's Dutch engineer, Jaar Haartensen, is recognized as the inventor of Bluetooth. Haardsen said he had developed the standard in 1994, but for a long time he did not know how to baptize him.

Why is Bluetooth called Bluetooth?

Although Ericsson has invented the technology, they also needed other companies to accept Bluetooth and use it in their devices. The name actually comes from Intel, an Ericsson partner whose employee Jim Krädach offers it.

The technique is named after one of the kings of Denmark and Norway, Harald Bludut. He is famous for joining the Danish tribes in a kingdom, similar to Bluetooth technology that combines communication protocols.

Who owns the Bluetooth standard?

No "does not own" Bluetooth, but its use and progress is handled by someone else. In order to ensure that Bluetooth will become a universal communication protocol, 1998 joined a group of companies to form the Bluetooth Special Interests Group (SIG), an ideal group.

Today, Bluetooth SIG is committed to developing new Bluetooth standards like Bluetooth 5 and licensing technology and membership. Currently, Bluetooth SIG has over 30,000 members.

How does Bluetooth work?

Bluetooth transmits data using low-power radio waves, mostly in the 2.4 GHz spectrum. This short-term frequency is often used by most devices that need a wireless connection, including Wi-Fi routers.

What distinguishes Bluetooth from other wireless standards is the use of a technology called frequency hopping. It's a sophisticated technique, but that's just an explanation. Bluetooth uses 79 radio frequency bands at the above 2.4 GHz frequency. When you send data, Bluetooth is first shared in smaller packages. These packages are sent separately via these 79 bands, and Bluetooth can swap bands quickly so no line is clogged.

Thanks to this intelligent "jump" of data, Bluetooth can simultaneously connect up to eight devices and let them communicate with each other.

Uses bluetooth data

No! Bluetooth does not use data. When Bluetooth connects two devices, it forms something called the PAN network. PAN does not require an internet or mobile file transfer service or anything else.

Bluetooth specifications

You may have heard that Bluetooth is divided into Basic Rate / Enhanced Data Rate (BR / EDR) and Low Energy (LE). This is before, and you should no longer handle this breakdown. Most devices on the market in the last five years have Bluetooth 4.0, 4.1 or 4.2 – all of which have low energy priority.

This process of breaking data into smaller packages and sending them separately is also the reason that Bluetooth is mainly used for small data transfers that do not need to happen quickly. If you need to quickly transfer large amounts of data, there are better wireless Bluetooth protocols. Specifically, Bluetooth 4.2 can send data up to 1 Mbps, which increases to 2 Mbps with Bluetooth 5. The distance between devices is about 10-15 m for Bluetooth 4.2, but comes up to 40 m with Bluetooth 5.

What is the difference between Bluetooth and Wi-Fi?

Technically, Wi-Fi and Bluetooth wireless protocols allow two devices to communicate with each other without cables. But the benefits and uses of each of these techniques are different. Wi-Fi is a stronger and faster connection, so it consumes more battery. Bluetooth focus is on battery performance.

My computer or laptop supports Bluetooth?

Bluetooth is a common and widely used technology supported by most smartphones, tablets, laptops and other wireless user devices. On desktop computers, however, the technology is not common. If your computer does not support Bluetooth, you can use a motherboard with built-in Bluetooth.

Is Bluetooth technology safe?

Over the years, security experts have discovered several Bluetooth vulnerabilities. The latest major vulnerability, called BlueBorne, was opened in 2017. Bluetooth SIG ensures that they have settled it in good time. However, there are some steps you can take to ensure extra security:

1. Change the four-digit PIN for your Bluetooth. Usually this is a simple procedure that varies from unit to unit. The most common default PIN is 0000 and hackers know it, so change it as soon as possible if you have not already.

2. Turn off Bluetooth when you are not using it. This is the best thing you can do to ensure the security of your data.
