What is Bluetooth, and how does it work? Bluetooth is a widely spoken topic, especially in the early 2000s. Before Spotify, we had to buy songs on our phones that could then be transferred to a friend's phone via Bluetooth. That was a fantastic way to share music before we could share our tunes on social media.

So what exactly is Bluetooth?

What is Bluetooth, and how does it work? Bluetooth is a widely spoken topic, especially in the early 2000s. Before Spotify, we had to buy songs on our phones that could transfer to a friend’s phone via Bluetooth. That was a fantastic way to share music before we could share our tunes on social media.

Bluetooth is a wireless technology that uses frequencies similar to a radio to share data over a short distance. Most Bluetooth devices connect at a maximum range of around 30 feet, but this distance gets reduced when obstacles like walls, for example, are in the way. For example, when sharing songs or pictures, you would need the two recipients standing next to each other for it to work. According to nature.co.uk, Bluetooth was publicly announced in May 1999 and released in July 1999. The launch of the first Bluetooth product, the wireless voice headset, followed. Nowadays, Bluetooth connects our phones to cars, headphones or even your smart fridge. According to statista.com, the leading actual wireless trending vendor is Apple. They also state that the Global Bluetooth audio and entertainment device shipments between 2015-2025 will be 1.7 Billion. 

What are the advantages?

Wireless Bluetooth headphones are used in the fitness industry due to their capability. A significant advantage of Bluetooth is that it doesn’t require wires. That allows athletes and gym goers to freely workout without worrying about cables.

Another great advantage to using Bluetooth technology is its simplicity. This technology is easy to use even if you have no previous knowledge. To use Bluetooth, you turn on your Bluetooth on both devices and make them discoverable to each other. The only possible issue is that both parties must be close to each other for the devices to connect. Some devices require a pin for quick and easy authentication. As long as the two parties are nearby and their Bluetooth is on. 

What are the disadvantages?

There are minor setbacks to technology. Bluetooth is very different from WiFi, as WiFi has a faster transfer rate. Bluetooth 3.0 and Bluetooth 4.0 both have a transmission rate of 25Mbps. Bluetooth is not ideal for transferring massive files like videos and would work best with documents. 

Another disadvantage to using Bluetooth is related to security risks. As much as Bluetooth has taken certain precautions to reduce various hackers, these problems still occur. Hackers can very quickly gain access to all your personal information using Bluetooth. The only way to reduce this happening to you is to turn off your Bluetooth when it’s not in use. That is one great example of why you should never transfer necessary documentation to others via Bluetooth. 

We now know how to use Bluetooth and reduce security risks. Bluetooth is a great invention. We all enjoy using Bluetooth. Will Bluetooth continue being used in the future?
