Initially named as “short-link”, Bluetooth is wireless technology to connect two devices placed at a short distance from each other. The idea to create Bluetooth technology was to discard cables or wires and still have communication between devices placed next to each other.

Name and Logo


Jim Kardach of Intel has proposed the name Bluetooth in 1997. He got the inspiration for the name from the novel “The Long Ships” written by Frans G. Bengtsson. The novel was about Vikings and King Herald Bluetooth.

The name “Bluetooth” is derived from Harald Bluetooth as he united dissonant Danish tribes into a single kingdom. In the same manner, Bluetooth technology was developed to unite different electronic devices.


The Bluetooth logo Bluetooth FM Color.png is a  bind rune merging the Youger Futhark runes Runic letter ior.svg (ᚼ, Hagall) and Runic letter berkanan.svg (ᛒ, Bjarkan), Harald’s initials.

Features of Latest Bluetooth Version 5.2

While December 6, 2016, marks the announcement of Bluetooth 5.0, still experts have been working on to make technology more advanced and user friendly and faster for end-user.

With the rise of the new decade, Bluetooth Special Interest Group(SIG) published an advanced version of Bluetooth known as Bluetooth LE Audio. Bluetooth Version 5.2 was issued on January 7, 2020.

With LE Audio, multiple devices will be capable to share data. As of now, the limit is two devices which can share music from a tablet, computer or phone.

The humans with hearing difficulties will get better audio experience.

The Technical specifications of Latest Bluetooth Version 5.2 over Bluetooth is to add new features viz:

1. Enhanced Attribute Protocol(EATT), an improved version of Attribute Protocol(ATT).
2. LE Power Control
3. LE Isochronous Channels.

Enhanced Attribute Protocol (EATT)

An upgraded version of ATT and enhancements to Generic Attribute profile has been announced as Enhanced Attribute Protocol(EATT).

With the new protocol, end-user can experience a reduction in end-to-end latency and improvement in the responsiveness of applications.

EATT can be used over an encrypted connection only so EATT has security advantage over existing ATT.

LE Power Control

To optimize the used transmission power between connected devices, LE Power control plays a major role. Bluetooth LE receivers will now be able to monitor the strength of the signal and can dynamically request transmission power level changes so that there is always a trade-off for signal quality and low power use.

Some advantages of LE Power control are as follows:

  1. Decrease in power consumption by sources.
  2. Enhancements in the dependability of receiver signal.
  3. Developments related to the existing and upcoming wireless devices.

LE Isochronous Channels

With Low Energy Isochronous Channels, there will be an improvement in the sound quality of hearing aids. Connection and broadcasting of sound to multiple devices are possible only because of Isochronous Channels.

Also, the day is not far when we can have multi-language audio systems as a result of this technology.

LE Audio

On January 7, 2020, at CES 2020, Bluetooth Special Interest Group announced new specifications which might be coming within the Bluetooth world. The new set of features will be rolled out with name LE Audio.

LE Audio may be made possible handiest after the feature of LE Isochronous Channels introduced in Bluetooth 5.2. This feature adds Isochronous data transport on the Bluetooth LE Radio.

LE stands for “Low Energy”. As the name suggests, LE will transmit data (sound) across devices on the low-energy spectrum. So to maintain the quality of Bluetooth, it will use the new compression algorithm.

The new Wireless merchandise can be predicted to be designed with discount in battery size which further reduces the size of the overall product.

The brand new devices in order to be compatible with this new set of specification might have playtime that is almost double the modern playtime.

Mark Powell, CEO of Bluetooth SIG remarked: “With close to one billion Bluetooth audio products shipped last year, wireless audio is the largest Bluetooth market.”

He further added, “The launch of LE Audio is a prime example of how the Bluetooth community is driving technology and product innovation and enabling delivery of even better and more capable Bluetooth audio products.”

LC3 – Low Complexity Communication Codec

  • LE Audio is comprised of recent codec LC3. It is low power and high-quality audio codec.
  • Developers can have huge flexibility and they are able to design the new wireless merchandise with better audio high-quality and less power consumption.

“Extensive listening tests have shown that LC3 will provide improvements in audio quality over the SBC codec included with Classic Audio, even at a 50% lower bit rate,” said Manfred Lutzky, Head of Audio for Communications at Fraunhofer IIS.
“Developers will be able to leverage these power savings to create products that can provide longer battery life or, in cases where current battery life is enough, reduce the form factor by using a smaller battery.”

Latest Bluetooth Version 5.2

Multi-Stream Audio

With the new feature of LE Audio, the data will be transmitted between multiple synchronized devices which may be independent of each other.

This new feature will enhance Bluetooth enabled devices to another level and will also demand innovation to a huge number of new merchandise of this category.

Have you faced a situation that when your kid’s favourite song is getting played in the car and at the same time you receive a call on your mobile which is also connected to a car stereo device through Bluetooth?

Now while you are on call instead of music you hear your baby’s crying voice because once your phone audio is connected, the music mutes completely and your baby does not like that.

So with the new multi Stream audio feature audio from both will be heard simultaneously.

Improvement in Hearing Aid

With Bluetooth technology, a large number of people have been benefited. No doubt wireless calling have made driving safer.

People have become more productive as many people take calls while driving to home or office. The advantages can also be counted as more people are entertained.

The other set of people that will be benefited from the new feature of LE Audio are the ones using hearing aids.

As per Stefen Zimmer, the Secretary-General of EHIMA( European Hearing Instrument Manufacturing Association), soon new phones and TVs will be easily manageable to people who have hearing loss.
