BY now we all know what Bluetooth is. Many gadgets and cell phones use Bluetooth 2.0 to transfer and receive data. So what's new about Bluetooth 3.0? Well, it would feature an increased data transfer speed to transfer large audio and video files. The transfer speed has dramatically increased from 3 Mbps to 24 Mbps. It also includes a new feature known as the Enhanced Power Control that would reduce disconnects if the device is moved to a pocket or briefcase during data transfer. It also uses Generic Alternate MAC/PHY (AMP) which allows it to operate at Wi-Fi speeds. The only disadvantage is that if a device has a different version of Bluetooth, it wouldn't be able to establish a connection with a device having Bluetooth 3.0. So if one has a multiple device supporting Bluetooth 2.0, he would definitely have second thoughts of purchasing a device supporting Bluetooth 3.0.
