The Specs for new version of bluetooth are out. The specification are now known as Bluetooth 3.0 High Speed and for a good reason - it promises up to 8 times the speed of version 2.0 + EDR (Enhanced data rate) for a theoretical maximum of 24Mbps. Isn’t that great. The increase in speed is achieved thanks to the 802.11 radio protocol. Note that 802.11 is not Wi-Fi, Wi-Fi is just an implementation of the 802.11 standard. Despite this, the new Bluetooth version aims to help Bluetooth do a lot of the things that Wi-Fi was better at.
