Bluetooth is a network technology that connects mobile devices wirelessly over a short range to form a personal area network (PAN). They use short-wavelength, ultra-high frequency (UHF) radio waves within the range of 2.400 to 2.485 GHz, instead of RS-232 data cables of wired PANs.
Features of Bluetooth
Bluetooth technology was released in 1999 as Bluetooth 1.0, by the Special Interest Group (SIG) which continues to manage it.
It was initially standardized as IEEE 802.15.1.
Mobile computing devices and accessories are connected wirelessly by Bluetooth using short-range, low-power, inexpensive radiOS.
UHF radio waves within the range of 2.400 to 2.485 GHz are using for data communications.
A PAN or a piconet can be created by Bluetooth within a 10 m radius.
