Bluetooth connectivity is essential in mobile telephony and today the vast majority of options on the market offer it. Were it not for it, we would not be able to connect our wireless headphones or smart watch and we would even lose the ability to transfer files to another mobile, although this last ability is hardly used due to the appearance of other channels.
This characteristic of current smartphones has evolved over time to give way to new standards that offer more and better advantages. The last of them is called Bluetooth 5.3, which offers the possibility of knowing the location of other connected devices while showing a transfer speed of 50 MB/S. However, it also guarantees another positive property that you should be aware of and that is worth taking a close look at.
The importance of the appearance of Bluetooth 4.0
To delve into the issue that this publication deals with, it is important to go back several years, specifically, to the emergence of the Bluetooth 4.0 standard back in 2010. This version of connectivity marked a before and after for mobile phones, since , in addition to maintaining a speed of 24 MB / s, reduced the battery consumption that this occasion produced.
However, the differentiating factor of Bluetooth 4.0 is that it prevented other users from connecting to the device without permission . This quality meant the end of malicious practices by cybercriminals who took advantage of this security gap when this function remained activated.
In short, anyone could establish a connection to your terminal without you noticing , since no warning arose. So, if you have a mobile phone that is several years old, it is a good idea to check if it has the Bluetooth 4.0 standard at least. Otherwise, it is advisable that you start looking for a substitute.
Likewise, it is important that you know in advance that Bluetooth is not updated as if it were the operating system, but rather it is an external technology that is developed over time. This means that only the most current releases boast the most advanced version, so it’s time to checkout if you want to get the most out of all its benefits.
What standard should you look for
The reality is that today there are practically no smartphones with Bluetooth version 4.0 or lower, so you have nothing to worry about, especially if you have in mind a phone from 2 or 3 years ago. In this sense, it is important that you know what Bluetooth standard your next purchase should have.
The ideal would be to look for a model that has at least Bluetooth 5.2 connectivity for several simple reasons: the first is because it improves the audio quality of connected devices, as well as its energy efficiency and the possibility of connecting to more than one device at a time. time. This coupled with the speed of 50 MB / s and the option to locate other connected devices in a specific range. Bluetooth 5.3 connectivity is also not decisive and is only available on high-end smartphones, so you don’t miss much.
