There are many diverse uses of Bluetooth devices, and with many novel and emerging technologies enabling users to connect with various devices with the help of Bluetooth technology the market for such products is growing rapidly, worldwide. A person could have Bluetooth headsets, earphones, USB dongles, and USB dongles with built-in antennas as well as Bluetooth GPS receivers. Bluetooth wireless technology is primarily a short-range communications technology developed to replace the cable connecting many devices in use today, and maintain high levels of security that is a hallmark of wired technology.

Inexpensive devices requiring low power with robust performance

Bluetooth devices are usually robust, consume very little power and are relatively inexpensive due to the technology used. To connect as well as communicate with one another using a Bluetooth device, there is a stack of protocols comprising Bluetooth specification that encompasses a wide range of such devices.

Bluetooth devices are rapidly being adopted by customers and they being used in many parts of the world. They can be connected to other Bluetooth enabled devices in close proximity. Such devices are able to connect as well as communicate without the need of wires through short-range, ad hoc networks that are called Pico nets. Each such device can simultaneously communicate with a maximum of seven other devices with just one Pico net, and a device may also be a part of several Pico nets simultaneously.
