Bluetooth Core Specification Version 5.2 released

Feature Overview (2/3)

LE Power Control

The new LE Power Control makes it possible for devices to dynamically optimize the transmission power used in communication between connected devices. Bluetooth LE receivers may now monitor signal strength and request transmission power-level changes in connected devices, typically to maintain an optimal signal strength from both a signal quality and low- power-use perspective. 

Benefits of the LE Power Control feature include: 1. The reduction of overall power consumption by transmitters through dynamic power management conducted between connected devices. 2. Improvements in reliability through the active maintenance of receiver signal strength so that it stays within the optimal range supported by the receiver. 3. Improvements relating to coexistence with other wireless devices that are in the environment and are using the 2.4 GHz frequency range. This benefit applies to all such devices, not just those that are using Bluetooth.
