How does energy consumption impact performance in Bluetooth?

In this paper we investigate the power characteristics of the Bluetooth technology when supporting low-power modes. We provide accurate power consumption measurements for different Bluetooth operating modes. Such information could be used to drive technical decisions on battery type and design of Bluetooth-based end systems. Finally, we examine the trade-off between power consumption and performance for a commercial off-the-shelf Bluetooth device. We find that the use of the sniff mode could be quite compatible with the use of multi-slot data packets. However, when the channel conditions require selecting single slot data packets, the sniff mode highly impact performance, and so the power/delay trade-off must be taken into consideration.
