Performance and Trade-offs of the new PHY Modes of BLE 5
Michael Spörk, Carlo Alberto Boano, Kay Römer · 2019
With the release of Bluetooth Low Energy (BLE) version 5, the Bluetooth Special Interest Group introduced three additional physical (PHY) modes for BLE communication. These PHY modes enable an application to either double its throughput, or significantly improve its reliability, making BLE applicable to an even wider range of application domains. Unfortunately, no experimental study has yet investigated the actual performance of BLE 5's PHY modes in BLE connections or shown their trade-offs between energy efficiency, reliability, and throughput. Thus, how to use BLE 5's PHY modes to achieve specific application requirements is still an open question.
