Difference between Bluetooth versions

What is Bluetooth? And what the differences between the Bluetooth versions such as 1.0, 2.0, 3.0, 4.0, 4.1, 4.2 and 5.0?

 

Bluetooth is a global communication standard that allows exchanging the data over certain distance. At one time Bluetooth technology was integrated into the earpiece that can communicate to your phone. But now it can do so much more in our daily life than before. It can connect to your device wirelessly which means no more cables.

Bluetooth 1.0 data transfer speed was just 1 Mbps, Bluetooth 2.0 data transfer speed is 3 Mbps, Bluetooth 3.0 data transfer speed increased up to 24 Mbps, Bluetooth 4.0 is upgraded in terms of other features, Bluetooth 4.1 was also upgraded in terms of other features whereas Bluetooth 4.2 increased its data transfer to 2.6x speed which is more faster than the previous version.

   For a surprisingly large number of smartphone and tablet users, Bluetooth is nothing more than the annoying logo displayed in the status bar and associated with an increase in battery consumption. What these users don’t see is the entire world of Bluetooth devices that can make a person’s life a lot easier and certainly more enjoyable.

Bluetooth 1.0

Bluetooth v1.0 was plagued with problems, compatibility issues, and, by today’s standards, a very slow maximum data of 1 Mbps. Only devices that belong to the museum use the first generation of Bluetooth, so there’s no chance of you actually encountering one in your local electronics store.

Bluetooth 2.0

After a few additional revisions of the first generation of Bluetooth, the Bluetooth Special Interest Group released Bluetooth v2.0 in 2004. It featured an Enhanced Data Rate (EDR) for faster data transfer speeds of up to 3 Mbit/s.

Bluetooth 3.0

Bluetooth 3.0 also known as a high-speed Bluetooth version is significantly faster than Bluetooth 2.0. Many budget wireless headphones/earphones come with the Bluetooth 3.0 technology. Bluetooth 3.0 also uses Enhanced Power Control (which means Smartphone can adjust at minimum power level needed for a quality connection while still increasing power when moving further from a paired device).

Bluetooth 4.0

Bluetooth 4.0 comes with additional benefits like increase in connectivity and better range. It is integrated with Bluetooth Low Energy protocol also known as Bluetooth SMART allows smart devices to be connected for a longer period of time without draining the battery. This new feature was aimed specifically at the healthcare, fitness, beacons, security, and home entertainment industries, and its impact is all around us. This is the major advantage in Bluetooth 4.0 over Bluetooth 3.0.

Bluetooth 4.1

Bluetooth 4.1 technology, which is currently featured in headphones like the MEE x7 Plus earbuds and others, can better manage their power and that of the device they are paired to by automatically powering up and down based on a power plan. Older versions of Bluetooth technology often interfered with other wireless technology, like 4G LTE communication.

Bluetooth 4.2

The latest iteration of Bluetooth is 4.2 technology. According to CSR, point two upgrades is said to dramatically increase speed 2.6x faster which means super speedy downloads that compared to older Bluetooth versions. In addition, privacy upgrades have been included in Bluetooth 4.1

Bluetooth 5.0

Global wireless technology continues to advance the IoT (Internet Of Things) experiences with the launch of Bluetooth 5. It doubles the speed, boosts broadcast messaging capacity by 800%, and increase range 4 times.
