Bluetooth Is More Than a Wireless Communication Protocol

As you can see, Bluetooth is not just a protocol used to exchange data between devices. The use of profiles further delineates the different kinds of applications that can be used with Bluetooth radio transmitters and thus makes it easier for manufacturers to produce portable devices that have applications built in and ready for use. You can contrast this with Wi-Fi, which simply provides the communications link just as traditional LAN or WAN protocols provide. Bluetooth provides both the radio frequency transport mechanisms and application-specific solutions that make interoperability between devices easy to implement.
