New Bluetooth spec boosts throughput, cuts power
A new Bluetooth standard is entering the prototype specification phase promising higher throughput with lower power consumption. Dubbed Bluetooth Enhanced Data Rate (EDR), the new spec increases throughput by compressing more data into each packet rather than sending more packets. The Bluetooth Special Interest Group claims that EDR's data throughput will peak at 2.1Mbps while potentially consuming half the power of traditional Bluetooth units.
Perhaps the mourning of Bluetooth's demise was a little premature. However, the wireless standard still faces stiff competition from existing 802.11x Wi-Fi and an emerging Wireless USB technology that Intel has thrown its considerable weight behind.
