Bluetooth 3.0 – A combination of Wi-Fi speeds, efficient power usage and more security .
The Bluetooth 3.0 specification was adopted by the Bluetooth SIG on April 21st, 2009.
Bluetooth is a standard for wireless communications between devices in a personal area network (PAN) using radio frequency for a short range (around 10 meters). earlier we have many version with different range and Data-tansfer Rate .
Bluetooth 3.0’s main benefit over its predecessor is its enhanced transfer speed. Whereas Bluetooth 2.1+EDR offered maximum speeds of around 3Mbps, the new version of the technology takes that up to around 24Mbps, through its use of the 802.11 radio protocol — better known as the basis for Wi-Fi.
Bluetooth 3.0 gets its speed from the 802.11 radio protocol. The inclusion of
the 802.11 Protocol Adaptation Layer (PAL) provides increased throughput of data
transfers at the approximate rate of 24 Mbps. In addition, mobile devices
including Bluetooth 3.0 will realize increased power savings due to enhanced
power control built in.
Now Users won’t have to connect to a Wi-Fi for high-speed file transfers .Transferring an entire music library, a complete DVD, a vacation’s worth of photos, all within seconds at the touch of a button and wirelessly will now be possible through only the Bluetooth 3.0 .
Improved Security
The Generic Alternate MAC/PHY in Bluetooth high speed enables the radio to discover other high speed devices only when they are needed to transfer your music, pictures or other data. Not only does this optimize power, but it also aides in the security of the radios.
