10 interesting facts about Bluetooth technology

Almost every device currently available on the market supports Bluetooth technology. But what is Bluetooth? Simply put, Bluetooth is a way for two interconnected modules to transfer data to each other.

Make Make Use of the app get curious about Bluetooth technology. From this we learn about the difference between Bluetooth technology and other common wireless technologies such as Wi-Fi or NFC, what are the advantages and disadvantages of the technology where the name comes from, and so on.

What is Bluetooth?

Bluetooth is a standard wireless technology to offer the ability to connect between these devices without a cable. The Bluetooth module is a small part of the chip on your device and allows you to wirelessly communicate with Bluetooth devices on other devices. In general, Bluetooth is used to transfer a small amount of data to prevent the use of too many batteries and maintain a stable connection over short distances.

Who invented Bluetooth technology?

Bluetooth technology was developed by a team of engineers working for Ericsson. Ericsson's electronics technician, Jaar Haartensen, is considered to be the inventor of Bluetooth technology. Haardsen said he had developed the standard in 1994, but for a long time he did not know how to baptize him.

Why is technology called Bluetooth technology?

Even though Ericsson invented this technology, it also needed other companies to accept Bluetooth and use it on their devices. The name actually comes from Intel, a Ericsson partner whose employee Jim Krädach offers.

This technology is named after one of the kings of Denmark and Norway, Harald Bludut. It is known for bringing together the Danish tribes in the kingdom, similar to Bluetooth communication protocols.

Who owns the Bluetooth standard?

Nobody "owns" Bluetooth, but its use and procedure is controlled by someone else. In order to ensure that Bluetooth becomes a universal communication protocol, a group of companies, which is a non-profit Bluetooth Special Interest Group (SIG), joined in 1998.

Today, Bluetooth SIG is engaged in developing new Bluetooth standards, such as Bluetooth 5 and partnering partner technology. At present, Bluetooth SIG has more than 30,000 members.

How does Bluetooth work?

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

The resolution of Bluetooth from other wireless standards is using a technique called "frequency broadcasting". It's sophisticated technology, but it's just an explanation. Bluetooth uses 79 radio frequency bands at the above 2.4 GHz frequency. When sending data, Bluetooth divides this data into smaller packages. These packets are sent separately through these 79 bands and Bluetooth can quickly change the bands, so no line is clogged.

With this intelligent "jump", Bluetooth can simultaneously connect up to eight devices and enable them to communicate with each other.

Does Bluetooth use data?

No! Bluetooth does not use any data. When Bluetooth connects two devices, it creates something called the Personal Area Network (PAN). PAN does not require internet or mobile file transfer service or anything else.

Bluetooth specifications

You may have heard that Bluetooth technology is divided into basic Speed ​​/ Speed ​​Enhanced Speed ​​(BR / EDR) and Low Energy (LE). This is in the past, and you should no longer have to deal with this division. Most devices in the market for the past five years have Bluetooth 4.0, 4.1 or 4.2, all of which have low priority.

This process of dragging data into smaller packages and sending them separately is also the reason why Bluetooth is primarily used for small data transfers that may not be fast. If you need to quickly transfer large amounts of data, there are better Bluetooth wireless protocols. Specifically, Bluetooth 4.2 can send data up to 1Mbps which will increase to 2Mbps using Bluetooth 5. The distance between devices is approximately 10-15m for Bluetooth 4.2 but reaches up to 40m with Bluetooth 5.

What is the difference between Bluetooth and Wi-Fi?

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

My computer or laptop support Bluetooth technology?

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

Is Bluetooth Technology Safe?

Over the years, security experts have discovered several Bluetooth security flaws. The last vulnerability, called BlueBorne, was opened in 2017. The Bluetooth SIG ensures that it fixes it in time. However, there are a few steps you can take to ensure additional security:

1. Change the four-digit PIN for your Bluetooth. Typically, this is a simple procedure that varies by device devices. The most common default PIN is 0000 and hackers know it, so you need to change it as soon as you have done so.

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