Bluetooth 3.0 introduced an Enhanced Data Rate mode which allowed higher throughput for faster file transfers between devices. Using a technique called AMP, compatible Bluetooth 3.0 radios could establish device-to-device 802.11 Wi-Fi connections for transfer speeds up to 24 Mbps. The basic rate for Bluetooth file transfers is only 721.2 Kbps.

Bluetooth 4.0 adds another layer to Bluetooth functionality and introduces low energy (LE) mode, which consumes only a fraction of the power that classic Bluetooth does, enabling a lifespan for devices comparable to active RFID. The Bluetooth Special Interest Group says devices powered by single button-cell batteries can operate for more than a year without recharging.
