To fully understand the power of Bluetooth, let's first check out some common use cases for the Bluetooth technology.

This type of printer is ideal for trade workers or busy professionals.

Row transfer: Computers, including infant - computers uniform PDAs and smartphones, can send files to each other via Bluetooth connections. You can transfer photos from a camera phone to a computer, install smartphone applications from a computer, or exchange documents between laptops importance a conference time.

Content provision: As mentioned earlier, Bluetooth can be used to nutriment photos, ringtones, and other multi - media contents to smartphones from computers. In fact, some retail stores have even installed Bluetooth booths to give mobile - phone content to customers.

But if you obtain elaborate devices that need to communicate with each other, the number of cables increases geometrically as the character of the devices does. Bluetooth becomes too many and more important as we carry too many and more personal gadgets. The Bluetooth solution is especially useful considering smartphones, as most smartphones profit non - standard and expensive propaganda cables.

To revenue advantage of Bluetooth devices and applications, we duty to learn a little about technology behind Bluetooth.
