Abstract:
This paper is investigating the energy saving potential of Bluetooth. Using the asynchronous connectionless link (ACL) for data transmission, Bluetooth provides different packet types, namely DM and DH packets. Each packet has a different payload size and in the actual implementation the packet selection is based on the channel conditions. In this paper we present and discuss results of a measurements campaign that we have made on commercial mobile phones. We show that energy savings can be achieved by selecting the appropriate packet type in an energy aware manner, by forcing the phone to use a specific packet type.
