By now we all know what Blue-tooth is. Many gadget and cellphone use Blue-tooth 2.0 to transfer and receive data. So what’s new about Blue-tooth 3.0? Well, it would feature an increased data transfer speed to transfer larger 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 use 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 Blue-tooth, it wouldn’t be able to establish a connection with a device having Blue-tooth 3.0. So if one has a multiple device supporting Blue-tooth 2.0, he would definitely have second thoughts of purchasing a device supporting Blue-tooth 3.0.
