The release of Bluetooth 5.2 has everyone in wireless communications – from analysts to consumers – excited about its game changing characteristics.

Bluetooth 5.2 promises to push us into the next level of high fi wireless audio as well as advanced  methods of communication, entertainment and interconnectivity. 

One important development is the Bluetooth Low Energy (LE) power control. Low energy was introduced with Bluetooth 4, but it was not sophisticated enough to be used with most practical applications, like streaming music.

With Bluetooth 5.2, larger amounts of information can finally be transmitted over lower bandwidth and at lower power. Essentially, this is achieved through the new LC3 codec, which results in information being more compressed on the input side, but being decompressed on the output side much more efficiently.

This is big news for those who want high quality Bluetooth audio, as that fidelity is going to be able to be much greater. The audio information is able to compress much smaller – which saves time and energy – but not lose any quality due to the efficiency and speed of the decode on the other side.

This revolutionary audio advancement is also due to a new feature called Isochronous Channels (ISOC). Isochronous (occurring at the same time) Channels support data transmissions that are time-sensitive and synchronized rendering of these data streams across multiple receivers.

The Bluetooth BLE Isochronous Physical Channel (ISOC) can be used on any of the LE PHYs: the 1M, 2M PHY and LE Coded PHY (including both s=2 and s=8 configurations).

Consequently, ISOC supports both connection-oriented and connectionless communication. In BLE terminology, this allows both connections and broadcasts to be supported.

The Bluetooth 5.2 version has also made giant strides with its 5 Enhanced Attribute protocol, which allows parallel transactions between two Bluetooth devices to occur simultaneously.

For instance, this would be useful if many apps on your smartphone are using a Bluetooth device at the same time. Instead of one being blocked while the others are in progress, these can all operate concurrently.
