Bluetooth 5.3 vs 5.2, 5.1 and 5.0: how are these technologies different?

The new version was announced in July 2021 and it was only released in May of this year. Bluetooth 5.3 seeks to reduce energy consumption in activities or jobs that are not necessary, as well as improve the security of connections

Bluetooth It is the wireless communication protocol between two devices, through a secure radio frequency in the 2.4 GHz ISM band. In this way, computers, smartphones, smartwatches, tablets and others can be connected to each other.

According to Yúbal Fernández, a Spanish journalist from Xataka, the Bluetooth 5.0 it is the basis of the new family of versions of this protocol. “This is the last big update that revolutionized Bluetooth 4, doubling the speed of file transfers and quadrupling the rangewhich is the distance at which they can transfer data between each other”, he pointed out.

In 2016, the version appeared 5.0 and changed the way devices were connected. “It continued with a low consumption thought of the IoT (Internet of Things) and allowed a greater amount of data in each transferred message”, added the journalist. Even in numbers it was better, arriving at a transfer rate of up to 50 Mb/s, and a distance of up to 240 meters.

Three years later the version came out Bluetooth 5.1. This focused on the location of devices, as well as the direction of the signals being searched for. The 5.2 arrived in 2020 and is also known as Bluetooth LE Audio. In it, it improvessound quality and energy efficiency across all devices that connect for audio features”. By using the new Low Complexity Communication Codec (LC3) it allows more efficient compression and decompression of data, and also the transfer of audio to multiple devices at the same time.

Bluetooth 5.3 adds to all of the above a lower consumption during use. “To improve performance by reducing power consumption, this version has added a filter for regular advertising process updates”, says Fernandez. This filter is used to discard the data that is repeated, thus saving energy.

It also improves by having less interference and more secure connections. “Peripherals can give their list of preferred channels so that the device that connects to them takes them into account and uses them over others. A) Yes, performance is improved and connection interference will be reduced”, adds the Spanish journalist.

Regarding security, the size of the encryption key has an increase in control. “If you are going to connect to a device that is not very secure due to using an encryption key that is too short, then the connection will not be established to protect you”, says Fernández, explaining that the driver can now tell the minimum size of the key.

Finally, the Bluetooth 5.3 It has a better quality based on the necessary bandwidth, so the devices will be able to choose these modes. “This means that if we’re using Bluetooth in a way that suddenly needs more bandwidth, like going from listening to music to making a call, this transition will be more effective”, he concluded.

However, it is the responsibility of the users in check that the devices used have this versionbecause if you connect, for example, a smartphone with Bluetooth 5.3 to a speaker with version 5.2, you will not see the improvements of the first one and you will only keep the one of the second.
