Bluetooth Technology: Changes That Occurred through History



At some point or the other, we have all used gadgets or devices that depend on Bluetooth services. Whether it is a headset or fitness gadget, Bluetooth has always been beneficial when it comes to ease-of-use. In the past few years, the technology that defines Bluetooth services has significantly evolved. Today, it is a part of almost every electronic gadget, which includes speakers, smartphones, headphones, computers, smartwatches, and so on.

Let’s take a look at the changes that have occurred with Bluetooth technology over the years.

1-Bluetooth 2.0 + EDR:

While the very first cellphone with Bluetooth functionality entered the market back in 2000, this technology gained prominence in the year 2004. This was because the 2004 version was easier for users to understand and incorporate within their daily activities. The 2.0 version brought in the EDR or Enhanced Data Rate technology with a maximum transfer rate of 3Mbit/s. However, in reality, this version allowed a maximum of 2.1 Mbit/s.

The 2.0 version reduced power consumption by half, which lead to its popularity.

2-Bluetooth 2.1:

Released in the year 2007, this particular version was updated with SSP or Secure Simple Pairing. As obvious from the name, this particular Bluetooth variant made the process for pairing simpler & secure. The SSP protocol needed encryption for any connections made within twocellphones. This made any potential attacks rather difficult which came from 3rd parties that relayed or intercepted messages exchanged between two different parties. This variant was released to bring down the battery consumption in devices such as headsets and keyboards that remain inactive mostly.

3-Bluetooth 3.0 + HS:

Bluetooth 3.0 + HS brought in key features such as high-speed for data transfer, Wi-Fi radio use, efficient power use, and so much more. Plus, the UCD or Unicast Connectionless Data introduction allowed the Bluetooth to be highly responsive. It also permitted the use of NFC or Near-Field Communication.

4-Bluetooth 4.0:

With improved range & connectivity followed by low-energy consumption, the Bluetooth 4.0 was primarily designed for frequent data transmission to smart devices. This allowed the implementation of batteries that looked like coins. With Bluetooth 4.0, gather data became easy from gadgets such as thermometers, heart monitors, fitness gadgets, and so on.

5-Bluetooth 4.1:

Introduced in the year 2013, the Bluetooth 4.1 version brought in changes for speed, hardware, as well as range. There were significant improvements in the software section as well. The prime focus for 4.1 version was laying down the groundwork for IoT devices.

6-Bluetooth 4.2:

Introduced in the year 2014, this particular version helped remove the range barriers completely. This allowed the devices to make use of the IPv6 or the Internet Protocol version 6 that enables direct access for the internet.

7-Bluetooth 5:

Latest in the lot, the Bluetooth 5 version is a steroid-packed version of all the past releases. It includes the best of all elements such as speed, range, IoT, as well as data capacity. Bluetooth 5 version is the fastest of all with the highest transfer speed for data transfer & software updates.
