Bluetooth 3.0 Specification Is Almost Ready

The Bluetooth Special Interest Group will announce the Bluetooth 3.0 specification on April 21st, according to PhoneScoop. The new specification will drastically increase speeds making video and audio transfers 'within seconds'.

The spec also includes a new ability called Enhanced Power Control. EPC will reduce the occurrence of disconnects that can be caused by actions such as putting a phone in a pocket, backpack, briefcase or purse. Bluetooth 3.0 uses Generic Alternate MAC/PHY (AMP). This is what lets Bluetooth profiles operate at Wi-Fi speeds.

The 802.11 Protocol Adaption Layer (PAL) will enable the Generic AMP feature to be used with an 802.11 radio. Bluetooth is used to create the pairing between two devices, but the data transfer itself is handed off to Wi-Fi. In order to take advantage of the higher transfer speeds, both devices need Bluetooth and Wi-Fi. If Wi-Fi isn't present on one of the devices, the spec reverts to Bluetooth for data transfer.
