743040_bluetooth_headset_4.jpgThe short range communication in wireless technology is Bluetooth. This wireless range works without any wires and can be connected to fixed devices while maintaining maximum security The main factors of Bluetooth are low cost and low power. It is the devise which is used to communicate and connect one another. The whole world today is using Bluetooth and they have become popular the world over.

The Piconets which are short range and networks can be connected via Bluetooth. A single Piconet can connect and communicate up to seven other devices

The fundamental to Bluetooth is its ability to handle both the data and voice communications at a time. This enables the user to enjoy variety of solutions like hands free talk, printing and fax and other such applications.

Specifications

The specifications of the Bluetooth helps support the data and voice applications.

Spectrum

The Bluetooth technology operates in the industrial and scientific band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping signal.

Interference

The adaptive frequency hopping of Bluetooth technology is designed to reduce interference between wireless technologies that share the 2.4 GHz spectrum. (AFH) Adaptive frequency hopping works well within the spectrum to take full advantage of the frequency available.

AFH hopping allows for more efficient transmission within the spectrum, which provides users with greater performance even if they are using other technologies along with Bluetooth.
