Bluetooth 5.3: more efficient, less interference and greater security

Bluetooth 5.3: more efficient, less interference and greater security

23 years have passed since the launch of Bluetooth 1.0 in 1999, and although it had many connectivity and security problems. It was the first stone of a technology that, today, is present in almost every home in the world. Today the most recent Bluetooth 5.3.

Yes ok, the new version 5.3 was announced in July 2021just now, almost a year after the news, it has begun to be integrated into some devices. There are several novelties and advantages that this improvement brings, and now I will detail each one of them.

Consumption, performance and safety

Unlike other versions, Bluetooth 5.3 can be considered as an evolution rather than a revolutionwhich mainly focuses its advances on three key points:

  1. Consumption: new technology will make compatible devices, have lower energy consumptionthus achieving greater efficiency, and consequently, can function for longer periods of time.
  2. Performance: At this level, now the peripherals will also be able to give their list of preferred channels. Not everything depends on a single central device, such as the cell phone. From now on, the Bluetooth connection will determine the channel preference of the two parties, achieving less interference and optimizing data transfer performance..
  3. Security: in this section, increases the control you have over the size of the encrypted keythat is, the driver will be able to set a minimum size that the encryption key must have to connect with another device. In this way, if the device to which you intend to connect is not considered secure, the connection will not be established..

In addition, this new jump in numbering adds Intelligent Dual Bluetooth function. The one that allows simultaneous connections to be established to the same device. As an example: two cell phones may be connected to the same speaker, both being able to control playback.

Bluetooth 5.3 Compatible Devices

Although the new technology is not yet widespread, there are a few devices that already implement it. In fact, the first announcement was made by Qualcomm, noting that Bluetooth 5.3 would be integrated into its FastConnect 7800 chipset. he himself did MediaTek in its Dimensity series, with its 8000 and 8100 models.

As for devices, the OPPO Reno 8 Pro or Redmi K50 and the Redmi Buds 4 Pro are compatible with the new version.

It is expected that during the second half of this year more manufacturers will include Bluetooth 5.3 in their devices.

How much use do you think you will be able to get out of this technology when you have a compatible team?
