What Is Bluetooth wireless technology?

Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400�2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security.

Created by telecom vendor Ericsson in 1994, Bluetooth was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.

Today, Bluetooth is applied in many areas including:

• Wireless control of and communication between a mobile phone and a handsfree headset. This was one of the earliest applications to become popular.
• Wireless control of and communication between a mobile phone and a Bluetooth compatible car stereo system.
• Wireless Bluetooth headset and Intercom.
• Wireless networking between PCs in a confined space and where little bandwidth is required.
• Wireless communication with PC input and output devices, the most common being the mouse, keyboard and printer.
• Transfer of files, contact details, calendar appointments, and reminders between devices with OBEX.
