Bluetooth 3.0 will be unveiled on April 21 which is expected to be 10 times faster than USB 2.0. with new specification achieves faster speeds with Wi-Fi (802.11n) technology. Bluetooth is not just merely a way to wireless pair a cell phone with a headset, but the technology is capable of transferring files, and even can be used by advertisers.
By utilizing Wi-Fi via an 802.11 Protocol Adaption Layer a Bluetooth 3.0 device will be able to pair with another device, and use Wi-Fi for the data transfer. If there's no Wi-Fi present, Bluetooth will be used. The new version also will have Enhanced Power Control, which is meant to reduce the number of disconnects that are caused by things like putting the cell phone in a pocket. Users won't have to connect to a Wi-Fi network to implement high-speed file transfers via Bluetooth.
On the technical side it is a Generic Alternate MAC/PHY (AMP) that will enable Bluetooth profiles to take advantage of 802.11 speeds. The 802.11 Protocol Adaption Layer (PAL) will enable the Generic AMP feature to be used with an 802.11 radio.
In other words, if it takes 10 minutes today to load up an Apple iPod with a wide selection of multimedia tracks, it would only take 60 seconds over a USB 3.0 connection, according to Intel. VIA
