What is Bluetooth?

bluetooth name

This technology was named in honor of Harald Blatand.

Bluetooth is a tool that has popularly been used to connect the mobile phone to the car or a speaker.

advantages and disadvantages

How does it work?

The Bluetooth specification defines a maximum communication channel of 720Kb/s (1Mbps raw capacity) with an optimal range of 10 meters (optionally 100m with repeaters).

Why is it called that?

After the joint effort of several companies, in 1999 the first version was published, named after Harald Blåtand, alias Bluetooth, the king of Denmark and Norway. Who, thanks to his reputation as a good communicator, achieved the unification of the Viking tribes under Christianity in the 10th century.

As proof of this tribute, the Bluetooth logo is composed of the juxtaposition of the runes equivalent to the king's initials.

What is bluetooth?

It is a wireless communication technology that can be used for short-range data transmission from one digital device to another. Bluetooth is essentially a one-to-one wireless connection that uses 2.4 GHz band radio waves

What is the function?

Bluetooth has a very well defined north and is based on being a technology that:– Establishes connections with little energy expenditure.– Establishes links that are generally short-lived.– Provides security through various forms of data encryption, in addition to requiring the use of a PIN to establish connections between devices.– Supports voice and data– It has a low production and implementation cost, it was proposed that it would not exceed US$5 per device..

Bluetooth was developed to replace cables and wires (Wireless), currently used to link or connect electronic devices, such as mobile phones, computers (personal computers), printers and a wide variety of portable devices.

How was Bluetooth developed?

The history of Bluetooth dates back to 1994, when the company Ericsson was developing a technology that allowed short-range communications with the benefit of using very little energy in devices (mainly mobile).The Dutch Jaap Haartsen and Mattisson Sven were the main developers.

it works like this...

The Bluetooth specification defines a maximum communication channel of 720Kb/s (1Mbps raw capacity) with an optimal range of 10 meters (optionally 100m with repeaters).The radio frequency with which it works is in the range of 2.4 to 2.48 Ghz with wide spectrum and frequency jumps with the possibility of transmitting in Full Duplex with a maximum of 1600 hops/sec. The frequency jumps occur between a total of 79 frequencies with intervals of 1Mhz; This allows for security and robustness.The output power to transmit at a maximum distance of 10 meters is 0 dBm (1 mW), while the long range version between 20 and 30 dBm (between 100 mW and 1 W).

Advantages of Bluetooth

• Eliminates all types of cables because the protocol is radio frequency.
• No type of connector is used as another great advantage.
• It is very easy to create a wireless network between several devices to be able to synchronize and exchange information.
• If one does not know much about technology, it is not difficult to learn how to use this protocol for the first time.
• It is completely free to use the service.
• It does not take away too much autonomy from devices that use Bluetooth because a few milli Watts are handled. This means that it is not an important factor for the wear of an electronic device battery.

• The speeds of the last two versions (3.0 and 4.0) are high (both 24MB/s).
• Another great advantage is also that it is popular worldwide. If one travels to Europe, for example, this technology is also used.

Disadvantages of Bluetooth:

• Security is a disadvantage of Bluetooth. Nowadays there have been improvements, especially in cell phones, but a few years ago, the protocol could be insecure because, if it was not configured correctly, it was vulnerable to the loss of information.
• The reduced scope of the protocol to exchange information is due to the low power it handles.
• The speeds of the first versions of Bluetooth that were released (1.2 and 2.0) are low (1MB/s and 3MB/s respectively).
• Limited range on most devices.
• Data transfer rate (24 Mbits/s)
• Incompatible linking protocols between devices.
• Requires data to be recorded locally to ensure uninterrupted availability.
